Agentic Coding Flywheel Setup (ACFS)

🌐 agent-flywheel.com — Interactive setup wizard for beginners

From zero to fully-configured agentic coding VPS in 30 minutes. A complete bootstrapping system that transforms a fresh Ubuntu or Arch-based machine into a professional AI-powered development environment.

Quick Install

{ acfs_installer="$(curl -fsSL "https://raw.githubusercontent.com/Dicklesworthstone/agentic_coding_flywheel_setup/main/install.sh")" || acfs_installer="$(curl -fsSL "https://cdn.jsdelivr.net/gh/Dicklesworthstone/agentic_coding_flywheel_setup@main/install.sh")"; } && printf '%s\n' "$acfs_installer" | bash -s -- --yes --mode vibe

The installer is idempotent—if interrupted, simply re-run it. It will automatically resume from the last completed phase without prompts.

Production environments: For stable, reproducible installs, pin to a tagged release or specific commit:

# Preferred: use a tagged release (e.g., v0.9.0)
curl -fsSL "https://raw.githubusercontent.com/Dicklesworthstone/agentic_coding_flywheel_setup/v0.9.0/install.sh" | bash -s -- --yes --mode vibe --ref v0.9.0

# Alternative: pin to a specific commit SHA
curl -fsSL "https://raw.githubusercontent.com/Dicklesworthstone/agentic_coding_flywheel_setup/abc1234/install.sh" | bash -s -- --yes --mode vibe --ref abc1234

Tagged releases are tested and stable. Passing --ref ensures all fetched scripts use the same version.

TL;DR

ACFS is a complete system for bootstrapping agentic coding environments:

Why you'd care:

• Zero to Hero: Takes complete beginners from "I have a laptop" to "I have Claude/Codex/Antigravity agents writing code for me on a VPS"
• One-Liner Magic: A single curl | bash command installs 30+ tools, configures everything, and sets up three AI coding agents
• Vibe Mode: Pre-configured for maximum velocity—passwordless sudo, dangerous agent flags enabled, optimized shell environment
• Battle-Tested Stack: Includes the complete Agent Flywheel stack (core tools + utilities) for agent orchestration, coordination, and safety

What you get:

• Modern shell (zsh + oh-my-zsh + powerlevel10k)
• All language runtimes (bun, uv/Python, Rust, Go)
• Agent coordination tools (NTM, MCP Agent Mail, SLB)
• Cloud CLIs (Vault, Wrangler, Supabase, Vercel)
• And 20+ more developer tools

Coding agents: 7 modules — 3 installed by default (Antigravity CLI, Claude Code, Codex CLI); 3 optional (Grok CLI, oh-my-pi, OpenCode); 1 legacy, off by default (Gemini CLI). Full roster in Compatible AI Coding Agents.

For Beginners

ACFS includes a step-by-step wizard website at agent-flywheel.com that guides complete beginners through:

1. Installing a terminal on their local machine
2. Generating SSH keys (for secure access later)
3. Renting a VPS from providers like OVH or Contabo
4. Connecting via SSH with a password (initial setup)
5. Running the installer (which sets up key-based access)
6. Reconnecting securely with your SSH key
7. Starting to code with AI agents

For Developers

ACFS is a one-liner that transforms any fresh Ubuntu or Arch-based machine into a fully-configured development environment with modern tooling and three AI coding agents ready to go.

For Teams

ACFS provides a reproducible, idempotent setup that ensures every team member's VPS environment is identical—eliminating "works on my machine" for agentic workflows.

Architecture & Design

ACFS centers its tool inventory and generated module metadata on the manifest. Generated installer libraries and doctor checks derive from it, while install.sh and several orchestration libraries retain explicit authored handoffs. Drift checks cover the seam between those two layers.

Why This Architecture?

Single Source of Truth: The manifest file (acfs.manifest.yaml) defines every tool—its name, description, install commands, and verification logic. When you add or edit a tool in the manifest, the generator automatically updates the generated scripts and manifest-derived checks. The production one-liner installer (install.sh) is still hand-written today, so behavior changes may also require updating install.sh until full migration.

TypeScript + Zod Validation: The manifest parser uses Zod schemas to validate the YAML at parse time. Typos, missing fields, and structural errors are caught immediately during generation—not at runtime on a user's VPS when the installer fails halfway through.

Generated Scripts: Rather than hand-maintaining one installer script per manifest category and keeping them synchronized, the generator produces them from the manifest. This means:

• A consistent, auditable view of manifest-defined install logic (some modules intentionally emit TODOs)
• Consistent error handling and logging across all modules
• A clear path toward future installer integration

Components

The Manifest System

acfs.manifest.yaml is the canonical inventory for generated ACFS modules. It defines their installation and verification metadata; authored orchestration remains responsible for bootstrap, lifecycle, and registered non-generated handoffs.

Manifest Structure

version: 2
name: agentic_coding_flywheel_setup
id: acfs
defaults:
  user: ubuntu
  workspace_root: /data/projects
  mode: vibe

modules:
  - id: base.system
    description: Base packages and sane defaults
    category: base
    run_as: root
    optional: false
    enabled_by_default: true
    generated: true
    phase: 1
    install:
      - apt-get update -y
      - apt-get install -y curl git ca-certificates unzip tar xz-utils jq build-essential
    verify:
      - curl --version
      - git --version
      - jq --version

Each module specifies:

• description: Human-readable name
• category: One of the canonical groups: base, users, filesystem, shell, cli, network, lang, tools, db, cloud, agents, stack, acfs
• install: Commands to run (or descriptions that become TODOs)
• verify: Commands that must succeed to confirm installation

The Generator Pipeline

The TypeScript generator (packages/manifest/src/generate.ts) reads the manifest and produces:

1. Category Libraries (scripts/generated/install_base.sh, install_agents.sh, etc.)

   • One source-only file per category with private module functions
   • Consistent logging and error handling
   • Verification checks after each module
   • Direct execution fails closed because a single category cannot satisfy cross-category dependencies

2. Doctor Checks (scripts/generated/doctor_checks.sh)

   • All verify commands extracted into a runnable health check
   • Tab-delimited format (to safely handle || in shell commands)
   • Reports pass/fail/skip for each module

3. Generated Harness (scripts/generated/install_all.sh)

   • Sources all category libraries
   • Invokes private module functions in global dependency order
   • Sourceable generated-module harness; direct execution refuses because it omits orchestration-owned modules and production dispatcher semantics

4. Runtime Data (scripts/generated/manifest_index.sh, internal_checksums.sh)

   • Deterministic module/category/generated-ownership metadata
   • Closed-grammar schema-1 digests for checksum-controlled runtime scripts

Note: Production install.sh is the only supported installation entry point. It sources the category libraries and dispatches their private functions through its phase runner; it does not call install_all.sh.

To regenerate after manifest changes:

cd packages/manifest
bun run generate        # Generate scripts
bun run generate:dry    # Preview without writing

Why TypeScript for Code Generation?

Shell can parse YAML with yq, but TypeScript + Zod offers:

• Type safety: The parser knows the exact shape of a manifest
• Validation: Zod catches malformed YAML with descriptive errors
• Transformation: Complex logic (sorting by dependencies, escaping) is natural in TypeScript
• Consistency: All generated code follows the same patterns

The generator centralizes the substantially larger Bash output in one reviewed TypeScript implementation. Exact line and file counts are intentionally derived from the current manifest rather than frozen in this document.

Security Verification

ACFS downloads and executes installer scripts from the internet. This is inherently risky—a compromised upstream could inject malicious code. The security verification system mitigates this risk.

How It Works

The checksums.yaml file contains SHA256 hashes for all upstream installer scripts:

# checksums.yaml
installers:
  bun:
    url: "https://bun.sh/install"
    sha256: "a1b2c3d4..."

  rust:
    url: "https://sh.rustup.rs"
    sha256: "e5f6a7b8..."

The security library (scripts/lib/security.sh) provides:

1. HTTPS Enforcement: All installer URLs must use HTTPS. Non-HTTPS URLs fail immediately.

2. Checksum Verification: Before executing a downloaded script, the system:

   • Downloads the content to memory
   • Calculates the SHA256 hash
   • Compares against the stored hash
   • Only executes if they match

3. Verification Modes:

   ./scripts/lib/security.sh --print              # List all upstream URLs
   ./scripts/lib/security.sh --verify             # Verify all against saved checksums
   ./scripts/lib/security.sh --update-checksums   # Generate new checksums.yaml
   ./scripts/lib/security.sh --checksum URL       # Calculate SHA256 of any URL
   

When Checksums Fail

A checksum mismatch can mean:

1. Normal update: The upstream maintainer released a new version
2. Potential compromise: Someone modified the script maliciously

The verification report distinguishes these cases:

• If multiple checksums fail simultaneously, investigate before updating
• If a single checksum fails after a known release, update is likely safe

To update after verifying a legitimate upstream change:

# Write to a candidate file first: redirecting straight onto checksums.yaml
# truncates it before the script runs, so a single fetch error would leave
# it empty and every verified installer would fail closed.
./scripts/lib/security.sh --update-checksums > /tmp/acfs-checksums.candidate.yaml
diff -u checksums.yaml /tmp/acfs-checksums.candidate.yaml   # Review what changed
cp /tmp/acfs-checksums.candidate.yaml checksums.yaml
git commit -m "chore: update upstream checksums"

Why This Approach?

The curl | bash pattern is controversial but practical. ACFS makes it safer by:

• Verifying content before execution (not just transport via HTTPS)
• Making checksums auditable in version control
• Providing tools to detect and investigate changes
• Failing closed (no execution on mismatch)

This is defense in depth—HTTPS protects transport, checksums protect content.

Omarchy (Arch) support

Omarchy (and Arch Linux generally) is supported by the same one-liner — no separate command required. The installer auto-detects your distribution and adapts:

• pacman instead of apt: system packages and CLI tools install via pacman.
• Your existing starship config is preserved: if you already have a customized starship.toml, ACFS leaves it alone rather than overwriting it.
• No oh-my-zsh / powerlevel10k on Arch: Arch users typically have an opinionated shell setup already, so the installer skips the oh-my-zsh + powerlevel10k phase instead of clobbering your prompt.

Everything else — language runtimes, AI agents, and the flywheel tool stack — installs identically to Ubuntu.

The Installer

The installer is the heart of ACFS—a modular Bash script that transforms a fresh Ubuntu or Arch-based machine into a fully-configured development environment.

Usage

Full vibe mode (recommended for throwaway VPS):

{ acfs_installer="$(curl -fsSL "https://raw.githubusercontent.com/Dicklesworthstone/agentic_coding_flywheel_setup/main/install.sh")" || acfs_installer="$(curl -fsSL "https://cdn.jsdelivr.net/gh/Dicklesworthstone/agentic_coding_flywheel_setup@main/install.sh")"; } && printf '%s\n' "$acfs_installer" | bash -s -- --yes --mode vibe

Interactive mode (asks for confirmation):

curl -fsSL "https://raw.githubusercontent.com/Dicklesworthstone/agentic_coding_flywheel_setup/main/install.sh" | bash

Safe mode (no passwordless sudo, agent confirmations enabled):

curl -fsSL "https://raw.githubusercontent.com/Dicklesworthstone/agentic_coding_flywheel_setup/main/install.sh" | bash -s -- --mode safe

Key Properties

Claude Code Settings Written at Install

The installer provisions a few keys in ~/.claude/settings.json, always merging non-destructively (a value you have already set is never overridden):

Resume Capability

The installer tracks progress in ~/.acfs/state.json. If interrupted:

• Re-run the same command—it resumes from the last completed phase
• No prompts or confirmations needed (with --yes)
• Already-installed tools are detected and skipped

To force a fresh reinstall of all tools:

curl -fsSL "https://raw.githubusercontent.com/Dicklesworthstone/agentic_coding_flywheel_setup/main/install.sh" | bash -s -- --yes --mode vibe --force-reinstall

Pre-Flight Check

Before running the full installer, validate your system:

curl -fsSL "https://raw.githubusercontent.com/Dicklesworthstone/agentic_coding_flywheel_setup/main/scripts/preflight.sh" | bash
curl -fsSL "https://raw.githubusercontent.com/Dicklesworthstone/agentic_coding_flywheel_setup/main/scripts/preflight.sh" | bash -s -- --json
curl -fsSL "https://raw.githubusercontent.com/Dicklesworthstone/agentic_coding_flywheel_setup/main/scripts/preflight.sh" | bash -s -- --format toon
curl -fsSL "https://raw.githubusercontent.com/Dicklesworthstone/agentic_coding_flywheel_setup/main/scripts/preflight.sh" | bash -s -- --network=skip

This checks:

• OS compatibility (Ubuntu 22.04+ or Arch-family: Arch, Omarchy; installer upgrades Ubuntu to 25.10)
• Architecture (x86_64 or ARM64)
• Memory and disk space (warns below 4GB RAM; fails below 20GB free disk)
• Network connectivity to required URLs
• Cached checksums.yaml availability for verified upstream installers
• APT lock status
• Potential conflicts (nvm, pyenv, existing ACFS)

Network checks performed:

For checksum-refresh review, compare a generated candidate without changing checksums.yaml:

candidate="/tmp/acfs-checksums.$$.candidate.yaml"
./scripts/lib/security.sh --update-checksums > "$candidate"
./scripts/preflight.sh --checksum-candidate "$candidate"

Common preflight failures:

Console Output

The installer uses semantic colors for progress visibility:

[1/8] Installing essential packages...     # Blue: progress steps
    Installing zsh, git, curl...           # Gray: details
⚠️  May take a few minutes                 # Yellow: warnings
✖ Failed to install package               # Red: errors
✔ Shell setup complete                    # Green: success

Automatic Ubuntu Upgrade

ACFS automatically upgrades Ubuntu to version 25.10 before installation when running on older versions. This ensures compatibility with the latest packages and optimal performance.

How it works:

1. Detects your current Ubuntu version
2. Calculates the upgrade path (e.g., 24.04 → 25.04 → 25.10)
3. Performs sequential do-release-upgrade operations
4. Reboots after each upgrade (handled automatically)
5. Resumes via systemd service after reboot
6. Continues ACFS installation once at target version

Expected timeline:

• Each version hop takes 30-60 minutes
• Full chain from 24.04 → 25.10 takes 1.5-3 hours
• SSH sessions disconnect during reboots (reconnect to monitor)

To skip automatic upgrade:

curl -fsSL "https://raw.githubusercontent.com/Dicklesworthstone/agentic_coding_flywheel_setup/main/install.sh" | bash -s -- --yes --mode vibe --skip-ubuntu-upgrade

To specify a different target version:

curl -fsSL "https://raw.githubusercontent.com/Dicklesworthstone/agentic_coding_flywheel_setup/main/install.sh" | bash -s -- --yes --mode vibe --target-ubuntu=25.04

Monitoring upgrade progress:

# Check current status
/var/lib/acfs/check_status.sh

# View upgrade logs
journalctl -u acfs-upgrade-resume -f

# View detailed logs
tail -f /var/log/acfs/upgrade_resume.log

Important notes:

• Create a VM snapshot before upgrading (recommended but not required)
• Upgrades cannot be undone without restoring from snapshot
• The system will reboot multiple times automatically
• EOL interim releases (like 24.10) may be skipped automatically if they are no longer offered by do-release-upgrade
• Reconnect via SSH after each reboot to monitor progress

The Update Command

After installation, keeping tools current is handled by acfs-update. It provides a unified interface for updating all installed components.

Usage

acfs-update                  # Update apt, runtimes, shell, agents, cloud CLIs, and stack tools
acfs-update --agents-only    # Only update coding agents
acfs-update --runtime-only   # Only update runtimes (bun, rust, uv, go)
acfs-update --dry-run        # Preview changes without making them
acfs-update --yes --quiet --no-self-update
                             # Automated mode that avoids changing the ACFS tree itself
acfs-update --bootstrap-self-update
                             # Explicitly convert a non-git or incomplete install into a git checkout

--bootstrap-self-update replaces ACFS repository files with origin/main. Copy local files elsewhere or commit local edits before opting in. Routine updates leave non-git and incomplete Git installs untouched.

The control-plane boundary: with --no-self-update (the shipped nightly timer's default), automated runs update your stack tools but never ACFS itself -- neither the git checkout nor the deployed runtime copies under ~/.acfs (bin/acfs, bin/acfs-update, scripts/lib/*.sh). The control plane therefore needs its own periodic refresh: run acfs-update without --no-self-update from time to time, or git pull --rebase the checkout and then run acfs-update --shell-only to redeploy the runtime copies. acfs doctor warns (updates.runtime_skew) when the checkout and the deployed runtime disagree, so a stack kept current by the nightly cannot silently outrun a stale dispatcher.

What Gets Updated

Options

Category Selection:

--apt-only       Only update system packages
--agents-only    Only update coding agents
--cloud-only     Only update cloud CLIs
--shell-only     Only update shell tools (OMZ, P10K, plugins, Atuin, Zoxide)
--runtime-only   Only update runtimes (bun, rust, uv, go)
--stack          Include Agent Flywheel stack tools (enabled by default)

Skip Categories:

--no-apt         Skip apt updates
--no-agents      Skip agent updates
--no-cloud       Skip cloud CLI updates
--no-shell       Skip shell tool updates
--no-runtime     Skip runtime updates (bun, rust, uv, go)

Behavior:

--force            Install missing tools (not just update existing)
--dry-run          Preview changes without making them
--yes, -y          Non-interactive mode (skip prompts)
--quiet, -q        Minimal output (only errors and summary)
--verbose, -v      Show detailed command output
--abort-on-failure Stop on first failure (default: continue)

Per-Tool Version Holds

When a single tool ships a regression, hold just that tool instead of pausing the whole nightly. Every hold records an owner, a reason, and an optional expiry, so a hold is a visible decision rather than silent version drift:

acfs hold br --version 0.4.1 --reason "0.5.2 cannot read existing beads DBs" --expiry 2026-09-15
acfs holds        # list holds (also surfaced by `acfs doctor` and every update summary)
acfs unhold br    # release the hold

Held tools are skipped by every update run with the owner/reason/expiry named in the log. Expired holds warn and are ignored. Holds live in ~/.acfs/holds.yaml.

Post-Install Verification and Rollback

Before a verified installer replaces a tool binary, the previous binary is retained at <binary>.prev. After the install, a smoke check probes the fresh binary with a per-tool argument (update_tool_smoke_probe in scripts/lib/update.sh: fsfs version, mdwb --help, pfr --help) or, for tools without an entry, the chain --version → --help → version. Every probe is headless-safe and runs with stdin detached under a 20 s ceiling. Verdicts:

• healthy — a probe exited 0.
• unsupported — every probe was rejected as an unknown argument (usage error). The binary ran, so it is kept and logged as POST-INSTALL VERIFICATION UNAVAILABLE; no rollback, no backoff.
• broken — a probe timed out, could not execute, died by signal, or failed without a usage-style rejection (crash, traceback, missing runtime). The previous binary is restored atomically and the failure is recorded in ~/.local/state/acfs/update-rollback.state so nightly runs back off instead of reinstalling the same broken release every night.

acfs doctor reports rolled back tools; acfs-update --force retries immediately.

acfs-update exit codes distinguish partial from total failure: 0 all succeeded, 1 total failure (nothing updated), 2 partial failure (some tools updated, some failed).

Logs

Update logs are automatically saved to ~/.acfs/logs/updates/ with timestamps:

# View most recent log
cat ~/.acfs/logs/updates/$(ls -1t ~/.acfs/logs/updates | head -1)

# Follow a running update
tail -f ~/.acfs/logs/updates/$(ls -1t ~/.acfs/logs/updates | head -1)

Why Separate from the Installer?

The installer transforms a fresh VPS. The update command maintains an existing installation. Separating them allows:

• Focused updates: Update just agents without touching system packages
• Dry-run previews: See what would change before committing
• Skip flags: Temporarily exclude categories that are working fine
• Stack control: Stack updates are included by default; skip with --no-stack
• Automated updates: Run via cron with --yes --quiet

ACFS CLI Commands

After installation, the acfs command provides a unified interface for managing your environment. Each subcommand is designed to be fast, informative, and scriptable.

Quick Reference

acfs info                    # Lightning-fast system overview
acfs cheatsheet              # Discover installed aliases
acfs dashboard generate      # Generate HTML status page
acfs doctor                  # Health checks
acfs newproj                 # Create a new project (TUI or CLI)
acfs agents update           # Regenerate the flywheel agent guide (ACFS-owned)
acfs agents install --help   # Explicitly deploy the guide (never overwrites)
acfs update                  # Update all tools
acfs holds                   # List per-tool version holds (acfs hold/unhold to manage)
acfs services status         # Check Agent Mail, CM, and CASS daemons
acfs services-setup          # Configure agent credentials
acfs continue                # View upgrade progress after reboot
acfs installer-cache build   # Cache checksum-pinned installer entrypoints

acfs installer-cache build — Verified Installer Entrypoint Cache

Build a portable acfs-installer-cache/ directory containing the checksum-pinned upstream installer scripts selected from acfs.manifest.yaml. On Ubuntu, pass either that directory or its parent to a later installation:

acfs installer-cache build --output /mnt/acfs-cache
./install.sh --yes --verified-installer-cache /mnt/acfs-cache

Explicit cache selection is fail-closed: if a required cached entrypoint is missing, stale, malformed, for another Ubuntu/architecture target, or does not match the current manifest and checksums.yaml, ACFS refuses it instead of fetching that entrypoint live.

This is not a complete offline installer. The cached entrypoint scripts still need network access for release archives, package registries, Git repositories, APT packages, and other transitive payloads. The initial ACFS bootstrap is also separate; use --bootstrap-archive for that layer. The roadmap below retains full pre-downloaded package bundles as future work.

acfs newproj — New Project Wizard

Create a new project directory with ACFS defaults (git init, optional br/beads, Claude settings, AGENTS.md). The interactive wizard is recommended for beginners.

Interactive wizard (recommended):

acfs newproj --interactive
acfs newproj -i
acfs newproj -i myapp         # Prefill project name

The wizard guides you through:

• Project naming and location
• Tech stack detection/selection
• Feature selection (br/beads, Claude settings, AGENTS.md, UBS ignore)
• AGENTS.md customization preview

• Minimum terminal size: 60x15.
• CLI mode skips existing AGENTS.md; the wizard overwrites it, so move it aside if you want to keep the old one.

acfs agents — Flywheel Agent Guide

ACFS generates a machine-wide agent guide (installed tools with live versions, workflows, safety rules). The guide lives only in ACFS-owned storage, and ACFS refreshes it there on install/update:

~/.acfs/docs/flywheel-agent-guide.md    # canonical, freely regenerated by ACFS
~/.acfs/docs/AGENTS.workspace.md        # workspace AGENTS.md template (canonical copy)

ACFS never automatically writes /AGENTS.md, ~/.codex/AGENTS.md, or a project's AGENTS.md — those files can contain user-authored rules and belong to you. (/data/projects/AGENTS.md is seeded once on a fresh install only when absent, and is never overwritten afterward.) Deploying the guide into a real instruction surface is an explicit step:

acfs agents update                       # regenerate the canonical guide
acfs agents path                         # print the canonical path
acfs agents install --codex-global       # deploy to ~/.codex/AGENTS.md (Codex global scope)
acfs agents install --project DIR        # deploy to DIR/AGENTS.md (project scope)
acfs agents install --workspace          # deploy to /data/projects/AGENTS.md
acfs agents install --root               # deploy to /AGENTS.md (legacy; not auto-discovered)
acfs agents install --to PATH            # deploy anywhere else

Deployment creates the destination only when it is absent. If the destination already exists with different content, the deploy refuses, leaves your file untouched, and writes a merge candidate next to it (<dest>.acfs-new) so you can diff and merge manually. Redeploying identical content is an idempotent no-op.

Discovery scopes worth knowing: Codex reads global guidance from ~/.codex/AGENTS.md and project guidance from the project root down to the working directory; filesystem-root /AGENTS.md is not automatically read by any major harness, which is exactly why ACFS no longer writes it.

Tool detection always runs in the target user's context (including under sudo, resolved via SUDO_USER with ~/.local/bin, ~/go/bin, etc. on PATH), so user-local tools are reported accurately.

acfs info — System Overview

Displays installation status in under 1 second by reading cached state (no verification).

acfs info                # Terminal output (default)
acfs info --json         # JSON output for scripting
acfs info --html         # Self-contained HTML page

Design Philosophy:

• Speed: Must complete in <1 second
• Read-only: Never verifies or tests (that's doctor's job). The one write it makes is benign: successful IP lookups are cached for an hour at ~/.acfs/cache/ip_address so repeat runs stay fast
• Offline: No network calls; IP discovery reads local interfaces and routing tables only
• Fallback: Graceful degradation if data missing

acfs dashboard — HTML Status Page

Generates a self-contained HTML dashboard and optionally serves it.

acfs dashboard generate              # Generate ~/.acfs/dashboard/index.html
acfs dashboard generate --force      # Force regeneration
acfs dashboard serve                 # Serve on localhost:8080
acfs dashboard serve --port 3000     # Custom port
acfs dashboard serve --public        # Bind to 0.0.0.0

The dashboard provides:

• System health at a glance
• Tool versions and status
• Quick command reference
• Recent activity summary

acfs services — Background Daemon Management

Start, stop, restart, inspect, or follow logs for the local coordination daemons:

acfs services start
acfs services status
acfs services logs agent-mail
acfs services restart cass     # restart one service; the others keep running
acfs services drift            # is the live process on the installed binary?
acfs services stop

Agent Mail keeps its ACFS-reserved 127.0.0.1:8765 endpoint and reuses the native user service when one is already healthy. CM runs on 127.0.0.1:8766, and CM plus the CASS watch indexer run in the acfs-svc tmux session. start and status return nonzero if any daemon fails its runtime readiness check.

Lifecycle contract (the tmux tradeoff chosen in #196, made explicit per #360):

• The installer does not start this service group; run acfs services start yourself after install (and after every reboot).
• start is a one-shot launcher, not a foreground supervisor: it brings the daemons up, reports readiness, and exits.
• Only Agent Mail is normally boot-persistent, via its native systemd user service. CM and the CASS watch indexer live in the acfs-svc tmux session, which does not survive a reboot and does not restart crashed processes -- after a reboot or crash, rerun acfs services start.
• CM's HTTP server is optional if you only use cm context / cm reflect from the CLI; those read the store directly.
• Leaving the CASS watcher off can be deliberate (for example while diagnosing indexing or resource problems); acfs services status reporting it "not running" is not necessarily a fault.

Converging a partly-down group (#383): when the acfs-svc session already exists, start repairs it instead of reporting and exiting. It relaunches only the services that are not running -- a pane whose process is alive is never touched, which matters when the tmux server also hosts long-lived agent panes. acfs services repair is the same operation under its own name.

Preflight before teardown (#382): restart resolves and validates every binary it will need before it stops anything. Validation is the post-install smoke check from #378 -- the binary must exist, be executable, and answer a probe; a broken verdict (timeout, wrong architecture, missing loader, crash) aborts the restart with no service-state change, while an unsupported verdict (the CLI rejects --version/--help/version as unknown arguments) is accepted. Managed binaries are resolved from the ACFS install directories as well as PATH, so a noninteractive SSH shell without ~/.local/bin on PATH no longer takes the group down. restart also accepts service names (acfs services restart cass) to restart one service without interrupting the others.

Running-binary drift (#381): updating a tool replaces the file on disk, but a service keeps executing the inode it started with -- cass --version then reports the new release while the live watcher still runs the old code. ACFS compares what each service executes (/proc/<pid>/exe, which is not the same thing as what PATH resolves) against the installed binary, and warns with both paths and hashes from acfs services status, acfs doctor, and the end of acfs update. Nothing is restarted automatically: the warning names the exact per-service restart command so you can pick a quiescent moment. acfs services drift runs the check on demand (--robot for one service|state|detail line per service). The comparison needs procfs, so it reports unknown on platforms without one.

This lifecycle command is distinct from acfs services-setup, which configures credentials and integrations rather than background processes.

acfs services-setup — Credential Configuration

Interactive wizard for configuring AI agent credentials and cloud service logins.

acfs services-setup          # Run full setup wizard

Guides you through:

• Claude Code: API key configuration
• Codex CLI: ChatGPT account login
• Antigravity CLI: Google account authentication
• GitHub CLI: gh auth login
• Cloud CLIs: Wrangler, Supabase, Vercel authentication

Also offers to install DCG (Destructive Command Guard), a Claude Code hook that blocks destructive commands like rm -rf /.

acfs continue — Upgrade Progress

After an Ubuntu upgrade reboot, view installation progress:

acfs continue                # Show current upgrade status

Learning Hub (Web)

In addition to the terminal-based onboarding, ACFS provides a comprehensive web-based Learning Hub at agent-flywheel.com/learn.

Web Lessons

The Learning Hub provides interactive lessons with progress tracking:

These are the core lessons; the hub ships 65 lessons in total (the core track plus per-tool deep dives such as UBS, Agent Mail, CASS, Beads, SLB, RCH and the case studies below), all defined in apps/web/lib/lessons.ts.

Features:

• Progress tracking in localStorage
• Code blocks with copy buttons
• Expandable deep-dive sections
• Practical exercises

Command Reference

The Command Reference documents every installed tool:

Technical Glossary

The Glossary defines 100+ technical terms with:

• One-liner: Quick tooltip definition
• Full explanation: Plain language description
• Analogy: "Think of it like..."
• Why we use it: Problem it solves
• Related terms: For context

Example entry:

RAM (Random Access Memory)
├── Short: Fast temporary storage your computer uses while working
├── Long: RAM is your computer's short-term memory...
├── Analogy: Like your desk space while working
├── Why: More RAM = run more programs simultaneously
└── Related: vCPU, VPS, NVMe

Flywheel Visualization

The Flywheel page visualizes tool interactions:

Plan (Beads) ──> Coordinate (Agent Mail) ──> Execute (NTM + Agents)
      ^                                              │
      │                                              v
      └──── Remember (CASS Memory) <──── Scan (UBS) ┘

Workflow Scenarios:

The scenarios are defined in apps/web/lib/flywheel.ts; the page renders whatever that file contains.

Tool Catalog (TL;DR page)

The TL;DR page is the searchable catalog of installed tools (the old /tools page was folded into it and now redirects there):

• Search & Filter: A search box (press / to focus) filters tools by name, CLI command, or description
• Tool Details: Each card shows the tool's tagline, its CLI command as a chip, and a copyable example invocation
• Synergy Diagram: An interactive diagram shows how the flywheel tools feed each other
• Live Data: Cards are generated from acfs.manifest.yaml — manifest tools without a hand-curated entry are auto-appended so the page can never silently omit a tool

This page helps users discover tools they may not know about and understand how each fits into the agentic coding workflow.

Interactive Website Components

The wizard website includes specialized components for guiding beginners:

ConnectionCheck Component: A prominent visual that helps users verify they're connected to their VPS before running commands:

• Side-by-side comparison: "Wrong (laptop)" vs "Right (VPS)"
• Terminal prompt examples for Windows, Mac, and Linux
• Clear "STOP!" warning with color-coded styling

CommandCard Component: CLI instruction cards with:

• Syntax-highlighted code blocks
• One-click copy button
• Platform-specific variations (bash/zsh/PowerShell)
• Expandable explanations

Jargon Component (Responsive Technical Terms): A tooltip system (apps/web/components/jargon.tsx) that adapts to the pointer type:

Desktop behavior:

• Hover or keyboard focus reveals a floating definition card, rendered through a portal so it escapes stacking contexts
• Viewport-aware positioning (auto-flips when near edges)
• A short close delay so the pointer can travel into the card

Mobile behavior:

• Tap opens a bottom sheet (apps/web/components/ui/bottom-sheet.tsx, framer-motion) with the full definition
• Swipe-to-dismiss from the handle, Escape and backdrop dismissal, focus returned to the term
• Body scroll locked while open and restored on close

Visual features:

• Dotted primary-colored underline marks a term as interactive
• Reduced-motion users get fades instead of slides
• Colors come from the OKLCH design tokens

Content structure per term:

{
  term: "VPS",
  short: "Virtual Private Server - a remote computer you rent",
  long: "A VPS is your own slice of a powerful computer...",
  analogy: "Think of it like renting an apartment in a building",
  whyWeUseIt: "You get root access, dedicated resources...",
  relatedTerms: ["SSH", "Ubuntu", "RAM"]
}

Confetti Celebration: On lesson completion:

• Burst of celebratory confetti particles
• Randomized encouraging messages
• Special celebration for completing all lessons
• Respects prefers-reduced-motion setting

Stepper Component: Multi-step progress indicator:

• Visual step-by-step progress
• Clickable navigation
• Completion checkmarks
• Mobile-responsive design

Expanded Lesson Library

The Learning Hub includes specialized lessons for each tool in the Agent Flywheel stack:

Each lesson includes:

• Conceptual introduction
• Practical commands with examples
• Interactive exercises
• Common pitfalls to avoid
• Links to tool documentation

Interactive Onboarding (TUI)

After installation, users can learn the ACFS workflow through an interactive terminal-based tutorial. The onboarding TUI discovers lesson markdown files dynamically from acfs/onboard/lessons, so the curriculum can grow as new tools and workflows are added without changing the launcher.

Running Onboarding

onboard                # Launch interactive menu
onboard status         # Show completion status
onboard --list         # Alias for status
onboard 3              # Jump to lesson 3
onboard reset          # Reset progress and start fresh
onboard --reset        # Alias for reset

Lessons

Run onboard --help to see the currently discovered lesson list. The curriculum currently spans Linux basics, SSH, tmux, agent login, NTM, the flywheel workflow, updating, Beads, RCH, and other ACFS tools. Because lessons are discovered by filename, adding a new NN_name.md file automatically extends the tutorial.

Progress Tracking

Progress is saved in ~/.acfs/onboard_progress.json:

{
  "completed": [0, 1, 2],
  "current": 3,
  "started_at": "2024-12-20T10:30:00-05:00"
}

The TUI shows completion status for each lesson and suggests the next one to take. Users can jump to any lesson or re-take completed ones.

Enhanced UX with Gum

If Charmbracelet Gum is installed, the onboarding system uses it for enhanced terminal UI—selection menus, styled prompts, and better formatting. Without Gum, it falls back to simple numbered menus that work everywhere.

Tools Installed

ACFS installs a comprehensive suite of 30+ tools organized into categories:

Shell & Terminal UX

Languages & Package Managers

Dev Tools

Networking

Tailscale provides secure, encrypted networking between your devices without complex firewall configuration:

# Authenticate and join your tailnet
tailscale up

# Check connection status
tailscale status

# Get your Tailscale IP
tailscale ip

# SSH over Tailscale (bypasses firewalls)
ssh ubuntu@your-vps.tailnet-name.ts.net

Benefits for agentic workflows:

• Firewall-free access: Connect even when behind NAT or restrictive firewalls
• MagicDNS: Access your VPS by hostname instead of IP
• SSH keys over Tailscale: Use tailscale ssh for key-free authentication
• ACLs: Fine-grained access control for team environments

Compatible AI Coding Agents

ACFS ships 7 coding-agent modules; 3 of them install by default.

Turn any of them on or off at install time with the Module column above: --only <module> installs that agent plus its dependencies, --skip <module> leaves it out — for example --only agents.grok or --skip agents.codex. --list-modules prints every module id and --print-plan shows what a given selection would run.

What each one is for:

• Antigravity CLI — Google's successor to the Gemini CLI; ACFS pins its model and permissions via agy-locked.
• Claude Code — Long autonomous runs with deep tool use; the ACFS default driver.
• Codex CLI — Runs on a ChatGPT plan; --device-auth is the login path on a headless VPS.
• Grok CLI — xAI's terminal agent; also accepts GROK_DEPLOYMENT_KEY for headless use.
• oh-my-pi — Community fork of the Pi agent with its own model roster and credential broker.
• OpenCode — Multi-provider harness; drives Claude, GPT, and Gemini models from one TUI.
• Gemini CLI — Retired upstream on 2026-06-18; kept installable for existing setups, use Antigravity instead.

Vibe Mode Aliases:

# Claude Code with max memory (background tasks enabled by default)
alias cc='NODE_OPTIONS="--max-old-space-size=32768" claude --dangerously-skip-permissions'

# Codex with bypass and dangerous filesystem access
alias cod='codex --dangerously-bypass-approvals-and-sandbox --search -m gpt-6-astra -c model_reasoning_effort=xhigh -c model_reasoning_summary_format=experimental'

# Antigravity CLI, model/settings/DCG locked by the ACFS launcher
alias agy='$HOME/.local/bin/agy-locked'
alias gmi='$HOME/.local/bin/agy-locked'

Installation & Updates: Claude Code should be installed and updated using its native mechanisms:

• Install: ACFS uses the official native installer (claude.ai/install.sh), checksum-verified via checksums.yaml (installs to ~/.local/bin/claude)
• Update: Use claude update --channel latest (built-in) or run acfs update --agents-only

This ensures proper authentication handling and avoids issues with alternative package manager builds. ACFS updates Codex with Bun global package updates, Antigravity with its native agy update path, oh-my-pi with its native omp update path, and Grok CLI by re-running its checksum-verified installer.

Cloud & Database

Vault is installed by default (skip with --skip-vault). ACFS installs the Vault CLI so you have a real secrets tool available early; it does not automatically configure a Vault server for you.

Supabase networking note: some Supabase projects expose the direct Postgres host over IPv6-only (often on free tiers). If your VPS/network is IPv4-only, use the Supabase pooler connection string instead (or upgrade/configure networking for direct IPv4).

Generated Doctor Checks

Doctor checks are generated from the manifest (scripts/generated/doctor_checks.sh) to keep verification logic close to acfs.manifest.yaml. The acfs doctor command automatically sources these generated checks to verify all manifest-defined tools.

How it works:

1. The manifest generator creates doctor_checks.sh with verify commands for each module
2. acfs doctor sources this file and runs each verification check
3. Failed checks display a fix suggestion with the exact command to reinstall

Example output with fix suggestion:

  ✗ tools.lazygit - Lazygit terminal UI not found
    Fix: curl -fsSL https://agent-flywheel.com/install | bash -s -- --yes --force-reinstall --only tools.lazygit

This architecture ensures doctor checks stay in sync with the installer—if a tool is in the manifest, it will be verified.

Options

acfs doctor              # Interactive colorful output
acfs doctor --json       # Machine-readable JSON output
acfs doctor --quiet      # Exit code only (0=healthy, 1=issues)
acfs doctor --deep       # Run functional tests (auth, connections)
acfs doctor --fix        # Apply safe fixes for failed checks
acfs doctor --dry-run    # Preview fixes without applying
acfs doctor --no-cache   # Skip cache, run all checks fresh

Deep Checks (--deep)

The --deep flag runs functional tests beyond binary existence:

Deep checks use 15-second timeouts to avoid hanging on network issues. Successful results are cached for 5 minutes to speed up repeated runs.

Example output:

Deep Checks
  ✔ Claude auth configured
  ✔ PostgreSQL connection working
  ⚠ Codex not authenticated (run: codex login)
  ✔ GitHub CLI authenticated

8/9 functional tests passed in 3.2s

Auto-Fix Mode (--fix)

The --fix flag automatically applies safe, deterministic fixes for common issues:

acfs doctor --fix             # Apply safe fixes
acfs doctor --fix --dry-run   # Preview fixes without applying

Safe Auto-Fixers

These fixes are applied when --fix is used. Failed checks are fixed right away; warning-level checks (which most of these are) additionally need --yes, so the usual invocation is acfs doctor --fix --yes:

Safety Guarantees

• Never deletes user files — Only creates, modifies, or symlinks
• Backups before modify — SHA256-verified backups of all modified files
• Idempotent — Safe to run multiple times
• Logged — All changes recorded to ~/.local/share/acfs/doctor.log
• Reversible — Configuration-level fixes (PATH, sourcing, config copies, symlinks, plugin clones) record an undo command; tool installs are not auto-reverted

Example Dry-Run Output

DRY-RUN: acfs doctor --fix

Would apply the following fixes:

  [fix.path.ordering]
    Action: Prepend PATH directories to ~/.zshrc
    File: ~/.zshrc
    Backup: Yes (SHA256 verified)

  [fix.acfs.sourcing]
    Action: Add ACFS sourcing to .zshrc
    File: ~/.zshrc
    Backup: Yes (SHA256 verified)

Fixes that require manual action:
  [shell.ohmyzsh]
    Status: FAIL
    Suggestion: curl -fsSL https://install.ohmyz.sh/ | bash

Summary: 2 auto-fixes, 0 prompted, 1 manual

Manual-Only Fixes

Some operations are never auto-fixed and instead provide suggestions:

• Package manager operations (apt install ...)
• Anything requiring sudo
• File deletions
• Complex shell configuration changes

Undoing Changes

All changes made by --fix can be undone:

acfs undo --list      # List all changes
acfs undo chg_0001    # Undo specific change
acfs undo --all       # Undo all changes from the most recent fix session
acfs undo --everything  # Undo every recorded change across all sessions

Wizard Steps

Key Features

• OS Detection: Auto-detects Mac vs Windows for tailored instructions
• Copy-to-Clipboard: One-click copy for all commands
• Handoff Runbook: Downloadable JSON/Markdown artifact for the installer command and recovery steps
• Progress Tracking: localStorage persistence across browser sessions
• Confirmation Checkboxes: "I ran this command" acknowledgments
• Troubleshooting: Expandable help for common issues

Wizard Handoff Runbook

Step 9 can download a local handoff runbook in JSON or Markdown. The runbook is meant for the user and support loop when an SSH session drops, an install is interrupted, or the user needs to remember the exact command they ran.

Schema: acfs.handoff-runbook.v1

Host addresses are not written into the runbook. The installer command stays exact so a user can paste it back into the VPS session, and the artifact points to support-report.md and manifest.json for support-bundle review.

Technology Stack

Next.js 16 (App Router)
├── React 19
├── Tailwind CSS 4 (OKLCH colors)
├── shadcn/ui components
├── Radix UI primitives
└── Lucide icons

No backend required. All state is stored in:

• URL query parameters
• localStorage (agent-flywheel-user-os, agent-flywheel-vps-ip, agent-flywheel-wizard-completed-steps)

Wizard State Management

The wizard uses TanStack Query for state management with optimistic updates and cross-tab synchronization:

Architecture:

// Query-based state with localStorage persistence
const { data: steps } = useQuery({
  queryKey: ['wizardSteps', 'completed'],
  queryFn: getCompletedSteps,  // Reads from localStorage
  staleTime: 0,                // Always check for updates
  gcTime: Infinity,            // Never garbage collect
});

Optimistic Updates with Rollback:

const mutation = useMutation({
  mutationFn: async (stepId) => {
    const newSteps = addCompletedStep(currentSteps, stepId);
    setCompletedSteps(newSteps);  // Persist to localStorage
    return newSteps;
  },
  onMutate: (stepId) => {
    // Optimistically update cache immediately
    const previousSteps = queryClient.getQueryData(queryKey);
    queryClient.setQueryData(queryKey, addCompletedStep(baseSteps, stepId));
    return { previousSteps };  // For rollback
  },
  onError: (_err, _stepId, context) => {
    // Rollback on failure
    queryClient.setQueryData(queryKey, context.previousSteps);
  },
});

Cross-Tab Synchronization: The wizard maintains sync across browser tabs via two mechanisms:

1. Custom DOM events for same-tab coordination between components
2. Storage events for cross-tab updates when localStorage changes

// Same-tab: custom event dispatch
window.dispatchEvent(new CustomEvent('acfs:wizard:completed-steps-changed', {
  detail: { steps }
}));

// Cross-tab: storage event listener
window.addEventListener('storage', (event) => {
  if (event.key === COMPLETED_STEPS_KEY) {
    queryClient.setQueryData(queryKey, getCompletedSteps());
  }
});

Safe localStorage Utilities: All localStorage access is wrapped in safe utilities that handle SSR, private browsing, and quota exceeded errors:

// Safe read (returns null on any error)
export function safeGetJSON<T>(key: string): T | null;

// Safe write (returns boolean success)
export function safeSetJSON(key: string, value: unknown): boolean;

// URL preservation for state fallback
export function withCurrentSearch(path: string): string;

This architecture ensures the wizard progress survives browser refreshes, works across tabs, and degrades gracefully when localStorage is unavailable.

Configuration Files

ACFS deploys optimized configuration files to ~/.acfs/ on the target VPS.

~/.acfs/zsh/acfs.zshrc

A comprehensive zsh configuration that's sourced by ~/.zshrc:

Oh-My-Zsh Plugins (14 total):

Note: zsh-autosuggestions and zsh-syntax-highlighting are custom plugins installed from GitHub. They must be listed last for optimal performance.

Path Configuration:

export PATH="$HOME/.local/bin:$PATH"
export PATH="$HOME/.cargo/bin:$PATH"
export PATH="$HOME/go/bin:$PATH"
export PATH="$HOME/.bun/bin:$PATH"

Atuin is still installed, but ACFS keeps it behind the guarded ~/.local/bin/atuin shim instead of putting ~/.atuin/bin at the front of interactive shell PATH.

Modern CLI Aliases:

alias ls='lsd --inode --long --all'
alias ll='lsd -l'
alias tree='lsd --tree'
alias cat='bat'
alias grep='rg'
alias vim='nvim'
alias lg='lazygit'

Tool Integrations:

# Zoxide (smarter cd)
eval "$(zoxide init zsh)"

# direnv (directory env vars)
eval "$(direnv hook zsh)"

# fzf (fuzzy finder)
source /usr/share/doc/fzf/examples/key-bindings.zsh

Shell Keybindings (Quality of Life):

Atuin History Bindings: ACFS intentionally does not enable Atuin's zsh preexec/precmd integration by default. Atuin's searchable CLI remains available as atuin search, but the automatic shell hook can record every coding-agent command and grow the Atuin database fast enough to make shells laggy.

~/.acfs/tmux/tmux.conf

A tmux configuration specifically optimized for NTM and multi-agent workflows:

Key Bindings:

Prefix: Ctrl+a (not Ctrl+b - more ergonomic)
Split horizontal: |  (preserves working directory)
Split vertical: -    (preserves working directory)
Navigate panes: h/j/k/l (vim-style)
Resize panes: H/J/K/L (repeatable with -r flag)
Reload config: r
New window: c (preserves working directory)

Copy Mode (vim-style):

Enter copy mode: prefix + [
Begin selection: v
Rectangle selection: r
Copy and exit: y

Agent Workflow Optimizations:

Catppuccin-Inspired Theme:

# Status bar (top position, less intrusive)
status-style: bg=#1e1e2e, fg=#cdd6f4

# Session indicator (blue accent)
status-left: #[fg=#89b4fa,bold] #S

# Active window highlight (pink accent)
window-status-current-format: #[fg=#f5c2e7,bold] #I:#W

# Pane borders
pane-border-style: fg=#313244
pane-active-border-style: fg=#89b4fa  # Blue highlight

Local Overrides: The config sources ~/.tmux.conf.local if it exists, allowing personal customizations without modifying ACFS defaults.

Library Modules

The installer is organized into modular Bash libraries in scripts/lib/:

logging.sh

Colored console output utilities:

log_step "1/8" "Installing packages..."  # Blue step indicator
log_detail "Installing zsh..."           # Gray indented detail
log_success "Complete"                    # Green checkmark
log_warn "May take a while"              # Yellow warning
log_error "Failed"                        # Red error
log_fatal "Cannot continue"              # Red error + exit 1

security.sh

HTTPS enforcement and checksum verification:

enforce_https "$url"                     # Fail if not HTTPS
verify_checksum "$url" "$sha256" "$name" # Verify before execute
fetch_and_run "$url" "$sha256" "$name"   # Verify + execute in one

os_detect.sh

OS detection and validation:

detect_os()      # Sets OS_ID, OS_VERSION, OS_CODENAME
validate_os()    # Checks for Ubuntu 25.10 (or upgrade path)

# Features:
# - Automatic logging to ~/.acfs/logs/updates/
# - Version tracking (before/after for each tool)
# - APT lock detection and warning
# - Reboot-required detection for kernel updates
# - Dry-run mode with --dry-run flag

gum_ui.sh

Enhanced terminal UI using Charmbracelet Gum:

print_banner()           # ASCII art ACFS banner
gum_step/gum_detail      # Styled output
gum_success/warn/error   # Colored messages
gum_spin                 # Spinner for long operations
gum_confirm              # Yes/No prompt
gum_choose               # Selection menu

Falls back to basic echo if Gum is not installed.

error_tracking.sh

Sophisticated error collection and reporting:

track_error "phase" "step" "error_message"
track_warning "phase" "step" "warning_message"
get_error_report                    # Generate structured error report
get_error_count                     # Count of tracked errors
has_errors                          # Boolean check for any errors

Features:

• Collects errors without aborting execution
• Associates errors with phase and step context
• Generates end-of-run summary reports
• Distinguishes warnings from errors

state.sh

State machine management for installation progress (v3 schema):

state_init                          # Initialize state file
state_get_phase                     # Current phase
state_set_phase "phase_name"        # Set current phase
state_mark_complete "phase_name"    # Mark phase complete
state_has_completed "phase_name"    # Check if phase done
state_save                          # Persist to disk (atomic)
state_load                          # Load from disk

The state file (~/.acfs/state.json) uses atomic writes to prevent corruption.

contract.sh

Runtime contract validation for generated scripts:

acfs_require_contract "module:${module_id}"  # Assert module environment is ready
acfs_check_contract                 # Non-fatal contract check

Validates that required environment variables and functions exist before execution:

• TARGET_USER, TARGET_HOME, MODE
• ACFS_BOOTSTRAP_DIR, ACFS_LIB_DIR
• Logging functions: log_detail, log_success, etc.

smoke_test.sh

Post-install verification that runs automatically after installation:

run_smoke_test                      # Execute all smoke tests

Critical Checks (must pass):

• Running as ubuntu user
• Passwordless sudo enabled
• Zsh is default shell
• Core tools accessible (bun, uv, cargo)

Non-Critical Checks (warnings only):

• Agent authentication configured
• Cloud CLIs authenticated
• Optional tools installed

Example output:

[Smoke Test]
  ✅ Running as ubuntu user
  ✅ Passwordless sudo enabled
  ✅ Zsh is default shell
  ✅ bun --version works
  ⚠️  Codex not authenticated (run: codex login)
  ✅ 8/9 checks passed

session.sh

Agent session export functionality for sharing and replay:

session_export "claude-code" "session_id" "/output/path"
session_list                        # List exportable sessions
session_validate "/export/file.json"

Implements the Session Export Schema for cross-agent sharing:

interface SessionExport {
  schema_version: 1;
  exported_at: string;              // ISO8601
  session_id: string;
  agent: "claude-code" | "codex" | "agy";
  model: string;
  summary: string;
  duration_minutes: number;
  stats: {
    turns: number;
    files_created: number;
    files_modified: number;
    commands_run: number;
  };
  outcomes: Array<{
    type: "file_created" | "file_modified" | "command_run";
    path?: string;
    description: string;
  }>;
  key_prompts: string[];            // Notable prompts for learning
  sanitized_transcript: Array<{
    role: "user" | "assistant";
    content: string;
    timestamp: string;
  }>;
}

tailscale.sh

Zero-config VPN setup for secure remote access:

install_tailscale                   # Install via official APT repo
verify_tailscale                    # Check installation
tailscale_status                    # Get connection status

Tailscale provides:

• Secure mesh networking between your devices
• SSH over Tailscale for firewall-free access
• MagicDNS for hostname-based addressing
• ACL-based access control

After installation, run tailscale up to authenticate and join your tailnet.

ubuntu_upgrade.sh

Multi-reboot Ubuntu version upgrade automation:

start_ubuntu_upgrade                # Begin upgrade chain
check_upgrade_status                # Current upgrade state
resume_upgrade_after_reboot         # Continue after reboot

Handles the complex multi-step Ubuntu upgrade process:

1. Detects current version
2. Calculates upgrade path (e.g., 24.04 → 25.04 → 25.10)
3. Performs sequential do-release-upgrade operations
4. Installs systemd service for post-reboot resume
5. Continues ACFS installation after reaching target

MCP Agent Mail Integration

ACFS includes integration with MCP Agent Mail for multi-agent coordination:

What Agent Mail Provides

• Identities: Each agent registers with a unique name
• Inbox/Outbox: Message-based communication between agents
• File Reservations: Advisory leases to prevent agents from clobbering each other's work
• Searchable Threads: Full-text search across all messages
• Git Persistence: All artifacts stored in git for human auditability

Port 8765 is reserved for Agent Mail

ACFS runs Agent Mail as a user service bound to 127.0.0.1:8765 and health-checks it there. cm serve (CASS Memory's MCP HTTP server) defaults to the same address, so on an ACFS machine start it on another port (cm serve --port 8766, or MCP_HTTP_PORT=8766 cm serve); otherwise whichever process starts second fails to bind and MCP clients can end up talking to the wrong server. If Agent Mail cannot start, the installer reports which process is holding the port.

Core Patterns

1. Register Identity:

# In your agent, call:
mcp.ensure_project(project_key="/data/projects/my-project")
mcp.register_agent(project_key=..., program="claude-code", model="opus-4.5")

2. Reserve Files Before Editing:

mcp.file_reservation_paths(
    project_key=...,
    agent_name="BlueLake",
    paths=["src/**"],
    ttl_seconds=3600,
    exclusive=true
)

3. Communicate:

mcp.send_message(
    project_key=...,
    sender_name="BlueLake",
    to=["GreenCastle"],
    subject="Review needed",
    body_md="Please review the auth changes..."
)

Macros for Speed

When speed matters more than fine-grained control:

mcp.macro_start_session(...)      # Ensure project + register + fetch inbox
mcp.macro_prepare_thread(...)     # Align with existing thread
mcp.macro_file_reservation_cycle(...)  # Reserve + work + release
mcp.macro_contact_handshake(...)  # Request contact permissions

Destructive Command Guard (dcg)

dcg is a high-performance Claude Code hook that blocks dangerous git and filesystem commands before they execute. Built in Rust for sub-millisecond latency, it provides mechanical enforcement of safety rules that instructions alone cannot guarantee.

Why dcg Exists

On December 17, 2025, an AI agent ran git checkout -- on files containing hours of uncommitted work from a parallel coding session. The files were recovered via git fsck --lost-found, but the incident made one thing clear: instructions in AGENTS.md don't prevent execution. dcg provides mechanical enforcement.

What Gets Blocked

What Gets Allowed

Safe variants are allowlisted:

• git checkout -b <branch> — Creates branch, doesn't touch files
• git restore --staged — Only unstages, doesn't discard
• git clean -n — Dry-run preview
• Temp directory cleanup still requires explicit human approval when an agent would delete files

Installation

acfs update --stack-only

Claude Code Configuration

Add to ~/.claude/settings.json:

{
  "hooks": {
    "PreToolUse": [
      {
        "matcher": "Bash",
        "hooks": [{"type": "command", "command": "dcg"}]
      }
    ]
  }
}

Modular Pack System

dcg uses a modular pack system for extensibility. Enable additional packs in ~/.config/dcg/config.toml:

[packs]
enabled = [
    "database.postgresql",
    "containers.docker",
    "kubernetes",
]

Available packs: database.*, containers.*, kubernetes.*, cloud.*, infrastructure.*, system.*, package_managers.

Repo Updater (ru)

ru is a production-grade CLI tool for synchronizing collections of GitHub repositories and automating commit workflows across dirty repos with AI assistance.

Core Features

• Multi-repo sync: Clone missing repos, pull updates, detect conflicts
• Commit sweep: groups uncommitted changes across repositories into logical conventional commits (plan first, --execute to apply)
• AI code review: Orchestrate Claude Code review sessions for open issues/PRs
• Work-stealing queue: Parallel execution with load-balanced workers
• NTM integration: Session management via Named Tmux Manager

Quick Start

{ curl -fsSL "https://cdn.jsdelivr.net/gh/Dicklesworthstone/repo_updater@main/install.sh" || curl -fsSL "https://raw.githubusercontent.com/Dicklesworthstone/repo_updater/main/install.sh"; } | bash

Initialize configuration:

# Initialize configuration
ru init --example

# Sync all repositories
ru sync

# Check status without changes
ru status

Commit Sweep Workflow

The commit-sweep command groups the changes in your dirty worktrees into logical conventional commits:

# Preview the commit plan (dry run is the default)
ru commit-sweep

# Execute the planned commits
ru commit-sweep --execute

# Keep manually staged files as their own group; limit to matching repos
ru commit-sweep --respect-staging --repos='*_rust' --execute

Two-Step Workflow:

1. Plan: Inspects every dirty worktree and prints the commits it would make
2. Execute: With --execute, makes those commits with deterministic git commands (never pushes)

Configuration

# ~/.config/ru/config
PROJECTS_DIR=/data/projects
LAYOUT=flat                   # flat|owner-repo|full
UPDATE_STRATEGY=ff-only       # ff-only|rebase|merge
PARALLEL=4

Repo list format (~/.config/ru/repos.d/public.txt):

owner/repo
owner/repo@develop            # Pin to branch
owner/repo as custom-name     # Custom directory name

CI/CD

ACFS does not use GitHub Actions: every workflow under .github/workflows/ is disabled, and the checks below run locally or on the maintainer's own machines (scripts/release-doctor.sh, scripts/checksum-monitor-local.sh on a systemd timer, the Docker and QEMU factory harnesses, and dsr for releases). The workflow descriptions that follow document what each disabled workflow used to do and what replaced it.

Installer Testing (installer.yml)

# Runs on every push and PR
jobs:
  shellcheck:
    - Lints all bash scripts with ShellCheck

  integration:
    - Matrix tests across Ubuntu 24.04, 25.04, 25.10
    - Runs full installation in Docker
    - Verifies all tools installed correctly
    - Runs acfs doctor to confirm health

  factory-e2e:
    - Runs the literal public curl|bash installer on QEMU/KVM or a fresh real Ubuntu host
    - Requires systemd, SSH, and a disposable factory VM/VPS semantics
    - Verifies ubuntu user creation, SSH key merge, user services, tool health, and idempotency

Docker catches shell and package regressions early. The factory E2E is the authoritative release gate for the real beginner VPS path because it exercises systemd, SSH, login/user-service behavior, and provider image defaults that containers cannot model. A Docker pass is not sufficient release proof by itself.

Local Release Doctor (scripts/release-doctor.sh)

Run the local release gate before tagging or publishing a release candidate:

bash scripts/release-doctor.sh --full --network=check
bash scripts/release-doctor.sh --json --full --network=check > release-doctor.json

For a fast local readiness check while developing:

bash scripts/release-doctor.sh --json

The release doctor composes the maintainer checks that are easy to forget:

• branch policy and clean worktree status
• shellcheck install.sh scripts/**/*.sh
• manifest/generated/checksum drift via scripts/check-manifest-drift.sh --json --quiet
• verified-installer checksum candidate review with --network=check
• website type-check, lint, and production build when apps/web changed or --full is set

The checksum candidate check uses the canonical updater output. If the generated body differs from checksums.yaml, review the diff before release; if only the timestamp header differs, leave checksums.yaml unchanged. The default --network=skip keeps routine runs offline, and --web=auto runs website checks only when web files changed unless --full or --web=always is provided.

Stack Provenance Report (scripts/stack-provenance-report.sh)

Use the stack provenance report when reviewing Agent Flywheel stack tool freshness before release:

bash scripts/stack-provenance-report.sh --json
bash scripts/stack-provenance-report.sh --network=check --json

Offline mode reports local manifest/checksum consistency for stack tools. Network mode also checks GitHub latest release metadata and generates a checksum candidate without writing checksums.yaml. Changed stack installer hashes fail the report, unrelated checksum diffs are called out separately, and rch release changes are flagged as mandatory checksum-refresh review items.

Agent Readiness Audit (scripts/agent-readiness-audit.sh)

Run the local agent readiness audit before launching a swarm on a freshly installed VPS:

bash scripts/agent-readiness-audit.sh
bash scripts/agent-readiness-audit.sh --json

The audit checks Claude Code, Codex CLI, Antigravity CLI, and caam without printing token values or auth file contents. It reports CLI presence, version availability, parseable auth/config files, CAAM default profile consistency, and stale CAAM defaults that point at missing profiles.

Useful options:

bash scripts/agent-readiness-audit.sh --no-version  # Skip CLI --version probes
bash scripts/agent-readiness-audit.sh --home /home/ubuntu --path "$PATH"

Treat failures as launch blockers. Warnings usually mean the CLI is installed but needs a user sign-in or CAAM default profile selection.

Website Deployment (website.yml)

# Builds and deploys the Next.js wizard
jobs:
  build:
    - Type-check TypeScript
    - Run ESLint
    - Build production bundle

  deploy:
    - Deploy to Vercel (production)

Automated Checksum + Drift Repair (scripts/checksum-monitor-local.sh)

ACFS monitors upstream installers for changes and repairs generated-artifact checksum drift from a local systemd timer (every 15 minutes, in a dedicated clone on a maintainer box), not from GitHub Actions; the retired checksum-monitor.yml did the same job and is kept only for reference.

scripts/checksum-monitor-local.sh      # the monitor
scripts/systemd/acfs-checksum-monitor.* # timer + service templates

How It Works:

1. Verify Generated Artifact Drift: Runs scripts/check-manifest-drift.sh --json to detect:
   • ACFS_MANIFEST_SHA256 mismatches
   • internal script checksum drift (scripts/generated/internal_checksums.sh)
   • generated installer and web metadata drift via bun run generate:diff
   • semantic manifest contract drift across scripts/generated/doctor_checks.sh, apps/web/lib/generated, acfs/onboard/lessons, README snippets, and checksums.yaml

The internal ledger is inert data: exactly ACFS_INTERNAL_CHECKSUMS_SCHEMA=1, one associative checksum map, and its exact entry count. The installer parses that closed grammar without sourcing the ledger, enforces its checksum-controlled membership, and verifies regular non-symlink files before sourcing them. This is an internal consistency boundary, not an independent signature or archive provenance claim. 2. Auto-Repair Drift: If drift is detected, runs --fix (regenerate + commit + push) 3. Verify Current Upstream Checksums: Downloads all upstream installers, calculates SHA256 4. Detect Upstream Changes: Compares against checksums.yaml 5. Categorize Tools: Separates "trusted" tools (can auto-update) from others 6. Auto-Update Upstream Checksums: Commits updated checksums.yaml when safe 7. Alert: For non-trusted tool changes, creates GitHub issue for manual review

The monitor fails closed when verification returns fetch errors or skipped entries; it will not emit partial/placeholder checksum updates.

What gets auto-updated: every changed installer hash — first-party and third-party alike — is regenerated with the canonical updater, committed, and pushed. The monitor fails closed (no partial update) if any fetch fails or any entry is skipped.

What gets flagged for review: when the changed set includes a third-party installer (anything whose URL is not under the Dicklesworthstone GitHub org: bun, uv, rustup, oh-my-zsh, atuin, zoxide, nvm, claude, antigravity, opencode, omp, grok), the monitor opens a GitHub issue with the diff after the update lands, so a human reviews the new upstream script post-hoc. First-party tool changes are committed without an issue.

This gives:

• Velocity: a fresh install is never broken by a stale hash for long
• Auditability: every hash change is a git commit, and third-party changes get an issue for review
• Fail-closed behavior: on fetch errors nothing is committed

Upstream Repo Dispatch (Fast Path):

• ACFS-owned tool repos emit a repository_dispatch event (upstream-changed) when their install.sh changes or a release is published.
• Requires a PAT secret named ACFS_REPO_DISPATCH_TOKEN in each tool repo (repo scope for this org/user).
• If dispatch fails, the 15-minute scheduled monitor still catches drift (but slower).

Production Smoke Tests (production-smoke.yml)

Validates deployments on real environments:

# Runs after deployment
jobs:
  smoke:
    - Fetches install.sh from production URL
    - Verifies checksum matches repository
    - Validates shell syntax
    - Confirms no uncommitted drift

Installer Canary (Docker) (installer-canary.yml)

Runs the installer inside fresh Ubuntu containers on a daily schedule. This is a fast regression canary, not the final proof of the factory VPS path.

schedule: "30 7 * * *" # daily
jobs:
  canary:
    - Run tests/vm/test_install_ubuntu.sh (vibe mode)
    - Defaults to Ubuntu 25.10; --all covers 24.04, 25.04, and 25.10
    - Uses ACFS_CHECKSUMS_REF=main for freshest hashes

Factory Installer E2E (installer-factory-e2e.yml)

Runs the literal public installer through the authoritative factory harness. The QEMU/KVM backend uses the official Ubuntu cloud image and requires a runner with /dev/kvm; set the repository variable ACFS_FACTORY_RUNNER, the manual runner input, or client_payload.runner to a KVM-capable larger/self-hosted runner. The real-host backend runs against a disposable Ubuntu VPS over SSH and is intended for provider-specific sentinel runs.

schedule: "0 8 * * 0" # weekly QEMU/KVM factory canary when ACFS_FACTORY_RUNNER has /dev/kvm
workflow_dispatch:
  inputs:
    backend: qemu|real-host
    runner: "" # optional override; blank uses ACFS_FACTORY_RUNNER or ubuntu-latest
    ref: main
    mode: vibe
    expect_ubuntu: "25.10"
    expect_final_ubuntu: "25.10"
repository_dispatch:
  types: [acfs-factory-host-ready]
real-host secrets:
  ACFS_FACTORY_SSH_PRIVATE_KEY: private key for real-host backend
  ACFS_FACTORY_SSH_TARGET: optional fallback root@fresh-host for real-host backend

Standard GitHub-hosted runners do not provide a contractual nested-virtualization environment. If the QEMU backend runs without /dev/kvm, the workflow fails at the KVM preflight with an environment-specific error before invoking the installer.

Reusable workflow callers may use the QEMU backend without passing SSH secrets. The real-host backend still needs a private key plus either client_payload.ssh_target for dispatch runs or ACFS_FACTORY_SSH_TARGET as a fallback.

If backend=real-host is requested without those SSH credentials, the workflow fails during configuration resolution. It must never report a green canary when no disposable host was tested.

Workflow artifact directories and uploads include only the current GitHub run id and attempt. That keeps repeated scheduled/manual runs from reusing or uploading old QEMU overlay disks on KVM-capable self-hosted runners with persistent workspaces. The QEMU backend writes its generated private SSH key outside the repository checkout, so upload-artifact and future Git commits never package guest login credentials. Factory diagnostics are redacted before local upload, including installer logs and the remote diagnostic archive.

The target host must be freshly provisioned. By default the harness fails if the ubuntu user already exists before install, because the real beginner path must prove ACFS creates that user automatically. The harness also requires acfs doctor --json to report zero failures and zero warnings, then separately verifies Agent Mail liveness/systemd service state and the ACFS nightly user timer.

For the slower upgrade/resume gate, provision a fresh Ubuntu 24.04 host and run the same workflow or script with --expect-ubuntu 24.04 --expect-final-ubuntu 25.10 --allow-install-reboot.

For provider-specific real VPS sentinels, use an external provisioning job to create a disposable server, wait for root SSH, dispatch acfs-factory-host-ready, and destroy the server after artifact collection. The dispatch payload should include the fresh host address so the repository does not store a stale long-lived VPS as ACFS_FACTORY_SSH_TARGET:

{
  "event_type": "acfs-factory-host-ready",
  "client_payload": {
    "backend": "real-host",
    "ssh_target": "root@203.0.113.10",
    "ref": "main",
    "mode": "vibe",
    "expect_ubuntu": "25.10",
    "expect_final_ubuntu": "25.10"
  }
}

Local QEMU Factory E2E (test_factory_install_qemu.sh)

Runs the same factory-host harness inside a real local VM instead of a Docker container. The wrapper downloads and verifies the official Ubuntu cloud image, boots it with QEMU/KVM and cloud-init, exposes root SSH on a local forwarded port, then delegates to tests/vm/test_factory_install_ubuntu.sh. Generated private SSH keys are kept outside the repository checkout; use --key-dir with a path under /tmp or another non-repo directory when you need a specific local key location for debugging.

sudo apt-get install -y qemu-system-x86 qemu-utils cloud-image-utils openssh-client
./tests/vm/test_factory_install_qemu.sh

Use this when Docker passes but you need local proof for systemd, sshd, cloud-init, kernel, filesystem, and login behavior before spending time on a disposable provider VPS.

VPS Providers

ACFS works on any Ubuntu VPS with SSH access and either root password login or a provider console that lets you become root for the first install. Here are recommended providers optimized for multi-agent workloads.

Why 48-64GB RAM? Each AI coding agent uses ~2GB RAM. To run 10-20+ agents simultaneously, you need 48GB+ RAM. Don't bottleneck a $400+/month AI investment to save $20 on hosting.

After installation, run acfs capacity --profile 25-agents --recommend-ntm on the VPS for a local RAM/CPU/disk sizing report with recommended agent counts and copyable NTM launch profiles.

Plan names, specs, and prices below were verified against the provider sites in 2026-08 (PRICING_LAST_UPDATED in apps/web/lib/vpsProviders.ts, the single source the wizard renders from).

Contabo (Best Value — Top Pick)

• Best specs-to-price ratio on the market
• Contabo lists EUR prices (24-month introductory rate, incl. VAT); the USD figures are approximate conversions
• Month-to-month terms are available; US datacenters may add a location fee (checkout shows the final price)

OVH (Small Plans Only)

• OVH's VPS range now tops out at VPS-4 (24GB); pick Contabo for the 48-64GB hosts this guide recommends
• Anti-DDoS included; polished control panel and fast activation
• "From" prices assume a 12-month term; month-to-month costs more

Requirements

| Requirement | Minimum | Recommended | | OS | Ubuntu 22.04+ (auto-upgraded) or Arch-family (Arch, Omarchy) | Ubuntu 25.10 | | RAM | 32GB (tight) | 48-64GB | | Storage | 250GB NVMe SSD | 300GB+ NVMe SSD | | CPU | 12 vCPU | 16 vCPU | | Price | ~$29/mo (48GB) | ~$43/mo (64GB) |

Other Providers

Any provider with an Ubuntu VPS, SSH access, and a first-login root password or root console works. The wizard at agent-flywheel.com has step-by-step guides.

# After reviewing and accepting the diff:
cp /tmp/acfs-checksums.candidate.yaml checksums.yaml

Manifest Validation

The manifest parser includes comprehensive validation beyond basic schema checking:

Validation Error Codes:

Running Validation:

cd packages/manifest
bun run validate              # Full validation
bun run validate --verbose    # Show all checks

Cycle Detection Algorithm:

Tarjan's strongly connected components (SCC):
1. DFS with discovery/low-link tracking
2. Identify SCCs with size > 1 as cycles
3. Report cycle path for human debugging

Test Harness

ACFS includes a comprehensive test harness (tests/vm/lib/test_harness.sh) for integration testing:

# Source the harness
source tests/vm/lib/test_harness.sh

# Initialize test suite
harness_init "ACFS Installation Tests"

# Create test sections
harness_section "Phase 1: Base Packages"

# Run commands with automatic logging
harness_run "Installing curl" apt install -y curl

# Assert results
harness_pass "curl installed successfully"
harness_fail "curl installation failed"
harness_skip "Skipping optional test"

# Generate summary
harness_summary  # Outputs: 15 passed, 0 failed, 2 skipped

Sync Scripts

Sync scripts keep ACFS documentation aligned with upstream projects:

# Sync NTM command palette from upstream
./scripts/sync/sync_ntm_palette.sh

# Check if update available (without downloading)
./scripts/sync/sync_ntm_palette.sh --check

Current Sync Sources:

All sync scripts use the security library for HTTPS enforcement and content hashing.

Website Design System

The website uses a comprehensive design system (apps/web/lib/design-tokens.ts):

Color Tokens (OKLCH Color Space):

// Perceptually uniform colors
colors: {
  cyan:    "oklch(0.75 0.18 195)",   // Primary accent
  pink:    "oklch(0.7 0.2 330)",     // Secondary accent
  purple:  "oklch(0.65 0.18 290)",   // Tertiary
  success: "oklch(0.72 0.19 145)",   // Green
  warning: "oklch(0.78 0.16 75)",    // Yellow
  error:   "oklch(0.65 0.22 25)",    // Red
}

Shadow Tokens:

shadows: {
  cardHover: "0 20px 40px -12px oklch(0.75 0.18 195 / 0.15)",
  cardLifted: "0 25px 50px -12px oklch(0.75 0.18 195 / 0.2)",
  primaryGlow: "0 0 40px -8px oklch(0.75 0.18 195 / 0.3)",
}

Animation Presets:

animations: {
  hover: { scale: 1.02, transition: { duration: 0.2 } },
  tap: { scale: 0.98 },
  fadeIn: { opacity: [0, 1], transition: { duration: 0.3 } },
}

Accessibility:

• Reduced motion support via useReducedMotion hook
• Semantic HTML structure

FAQ

Why "Vibe Mode"?

Vibe mode is designed for throwaway VPS environments where velocity matters more than safety:

• Passwordless sudo eliminates friction
• Agent dangerous flags skip confirmation dialogs
• Pre-configured aliases for maximum speed

Never use vibe mode on production or shared systems.

Can I use this on my local machine?

ACFS is designed for fresh Ubuntu VPS instances. While you could run it locally:

• It may conflict with existing configurations
• It assumes root/sudo access
• It's not designed for macOS or Windows

For local development, use the individual tools directly.

What if the installer fails?

The installer is checkpointed. Simply re-run it:

{ acfs_installer="$(curl -fsSL "https://raw.githubusercontent.com/Dicklesworthstone/agentic_coding_flywheel_setup/main/install.sh")" || acfs_installer="$(curl -fsSL "https://cdn.jsdelivr.net/gh/Dicklesworthstone/agentic_coding_flywheel_setup@main/install.sh")"; } && printf '%s\n' "$acfs_installer" | bash -s -- --yes --mode vibe

It will skip already-completed phases and resume where it left off.

How do I update tools?

Use the built-in update command:

acfs update                  # Update all standard components
acfs update --stack          # Include Agent Flywheel stack
acfs update --agents-only    # Just update AI agents

How do I uninstall?

There's no uninstall script. To reset:

1. Delete the VPS instance
2. Create a new one
3. Run the installer fresh

This is intentional—ACFS is designed for ephemeral VPS environments.

Can I customize which tools are installed?

Currently, ACFS installs the full suite. Future versions will support:

• Manifest-based tool selection
• Interactive mode for choosing components
• Modular installation scripts

Why ACFS Exists

The Problem: The Agentic Coding Barrier

The rise of AI coding agents (Claude Code, Codex CLI, Antigravity CLI) has created a new paradigm in software development. These agents can write code, debug issues, and even architect solutions—but only if they have the right environment.

The barrier isn't the agents themselves. It's the hours of setup required to create an environment where agents can actually be productive:

└────────────────────────────────────────────────────────────────────────────┘

ACFS eliminates this barrier entirely. One command, 30 minutes, fully configured.

The Deeper Problem: Beginners Can't Start

For experienced developers, the setup is tedious but doable. For beginners—the people who would benefit most from AI coding assistance—it's an insurmountable wall:

• What's SSH? How do I generate keys?
• What's a VPS? How do I rent one?
• What's a terminal? Which one should I use?
• How do I connect to a remote server?
• What are all these tools and why do I need them?

The wizard website at agent-flywheel.com solves this by providing:

1. Absolute beginner guidance — Explains every concept in plain English
2. OS-specific instructions — Detects Mac vs Windows, shows the right commands
3. Visual confirmations — Checkboxes for each step, copy buttons for commands
4. Troubleshooting help — Expandable sections for common problems
5. Progress persistence — Resume where you left off across browser sessions

The 10x Multiplier Effect

ACFS isn't just a collection of tools—it's a carefully curated system where each component amplifies the others. The value isn't additive; it's multiplicative.

Why These Specific Tools?

Every tool in ACFS earns its place through concrete productivity gains:

The Compounding Effect

A single agent with basic tooling is useful. Three agents with:

• A shared project structure
• Coordination via Agent Mail
• Orchestration via NTM
• Safety guardrails via SLB
• DCG guard hook (blocks destructive commands before execution)
• Task visibility via Beads

...can accomplish in one day what would take a solo developer a week.

Tip: run acfs services-setup to configure logins, and enable DCG for destructive-command protection.

This is the flywheel effect in action. Better tools → more capable agents → more code shipped → better understanding of what tools are needed → better tools.

Design Algorithms & Decisions

ACFS implements several algorithmic patterns that ensure reliability and maintainability.

Idempotency Algorithm

Every installation function follows the check-before-install pattern:

install_tool() {
    if command_exists "tool"; then
        log_success "tool already installed"
        return 0
    fi

    # ... installation logic ...

    if command_exists "tool"; then
        log_success "tool installed successfully"
        return 0
    else
        log_error "tool installation failed"
        return 1
    fi
}

This guarantees:

1. Safe re-runs — Running the installer twice doesn't break anything
2. Resume capability — Failures don't require starting over
3. Declarative intent — The end state is defined, not the transition

Checksum Verification Algorithm

The security system uses content-addressable verification:

┌─────────────────────────────────────────────────────────────────────────┐
│  VERIFICATION FLOW                                                       │
│                                                                          │
│  1. Download script to memory (not disk)                                 │
│  2. Calculate SHA256 of downloaded content                               │
│  3. Compare against stored hash in checksums.yaml                        │
│  4. If match → execute                                                   │
│  5. If mismatch → refuse execution, report discrepancy                   │
│                                                                          │
│  Key insight: We verify CONTENT, not just transport                      │
│  (HTTPS only protects the channel, not the content at source)            │
└─────────────────────────────────────────────────────────────────────────┘

Manifest-Driven Generation

The generator uses a template expansion pattern:

1. Parse — Read YAML manifest, validate with Zod schemas
2. Transform — Convert manifest entries to installation functions
3. Group — Organize by category (base, shell, cli, lang, agents, etc.)
4. Generate — Emit Bash scripts with consistent structure
5. Verify — Generate doctor checks from verification commands

The manifest is the source of truth for generated modules and their verification metadata. Explicitly authored orchestration handoffs remain in install.sh and the installer libraries, so generator drift checks and integration tests are still required across that boundary.

Code Generator Architecture

The manifest generator (packages/manifest/src/generate.ts) is a sophisticated TypeScript program that transforms YAML into bash:

Input Processing:

// 1. Parse YAML with validation
const manifest = parseManifestFile(MANIFEST_PATH);  // Zod-validated

// 2. Load checksums for verified installers
const checksums = parseYaml(readFileSync(CHECKSUMS_PATH));

// 3. Topological sort for dependency order
const sorted = sortModulesByInstallOrder(manifest.modules);

Security-First Code Generation:

// Shell-safe quoting (prevents command injection)
function shellQuote(s: string): string {
  return `'${s.replace(/'/g, "'\\''")}'`;
}

// Allowlisted runners only (belt-and-suspenders)
const ALLOWED_RUNNERS = ['bash', 'sh'] as const;

// Verified installer file-backed execution
function buildVerifiedInstallerFileCommand(module: Module): string {
  // Runs the interpreter only after the complete script is checksum-verified
  // and staged in a read-only file.
}

bun run generate           # Full regeneration
bun run generate:dry       # Preview without writing

Generated Manifest Index

The generator produces manifest_index.sh, a comprehensive bash metadata file that provides programmatic access to manifest data at runtime:

Associative Arrays:

# Module metadata lookup
declare -gA ACFS_MODULE_DESC
ACFS_MODULE_DESC["lang.bun"]="Bun JavaScript/TypeScript runtime"
ACFS_MODULE_DESC["agents.claude"]="Claude Code CLI agent"

# Phase mapping (determines install order)
declare -gA ACFS_MODULE_PHASE
ACFS_MODULE_PHASE["base.system"]="1"
ACFS_MODULE_PHASE["lang.bun"]="6"
ACFS_MODULE_PHASE["agents.claude"]="7"

# Dependency relationships (comma-separated)
declare -gA ACFS_MODULE_DEPS
ACFS_MODULE_DEPS["agents.codex"]="lang.bun"
ACFS_MODULE_DEPS["stack.mcp_agent_mail"]="lang.bun,lang.uv"

# Generated function name mapping
declare -gA ACFS_MODULE_FUNC
ACFS_MODULE_FUNC["lang.bun"]="acfs_generated_install_lang_bun"
# generated:false modules deliberately have no ACFS_MODULE_FUNC entry

# Canonical category order and per-module generation ownership
declare -a ACFS_CATEGORIES_IN_ORDER=(base users filesystem shell cli network lang tools db cloud agents stack acfs)
declare -gA ACFS_MODULE_GENERATED
ACFS_MODULE_GENERATED["lang.bun"]="1"
ACFS_MODULE_GENERATED["users.ubuntu"]="0"

# Category grouping
declare -gA ACFS_MODULE_CATEGORY
ACFS_MODULE_CATEGORY["lang.bun"]="lang"

# Default inclusion in install
declare -gA ACFS_MODULE_DEFAULT
ACFS_MODULE_DEFAULT["lang.bun"]="1"
ACFS_MODULE_DEFAULT["db.postgres18"]="1"

Runtime Access Pattern:

# Iterate modules in deterministic install order
for module in "${ACFS_MODULES_IN_ORDER[@]}"; do
  [[ "${ACFS_MODULE_CATEGORY[$module]}" == "agents" ]] || continue
  printf '%s\n' "$module"
done

# Check if module is default-installed
[[ "${ACFS_MODULE_DEFAULT[tools.vault]:-1}" == "1" ]]

# Get installation phase
printf '%s\n' "${ACFS_MODULE_PHASE[stack.ntm]}"  # 9

Use Cases:

• acfs doctor queries module metadata for health checks
• install.sh --list-modules displays available modules
• --skip <module> validates module existence before skipping
• --only-phase <n|name> uses phase mapping for selective installs

The manifest index bridges the TypeScript generator with bash runtime, enabling sophisticated module selection logic while keeping the bash scripts simple.
