👋 What is Bob's Brain?

Bob's Brain is an ADK/Vertex compliance department that coordinates specialist AI agents for ADK standards enforcement, code quality, and documentation. Built on Google's ADK and Vertex AI Agent Engine, it features enterprise-grade infrastructure (risk tiers, policy gates, evidence bundles, workflow-as-code) that can power any domain-specific agent department.

Key Capabilities:

Enterprise Controls: Risk tiers (R0-R4), policy gates, tool allowlists
Audit Trails: Evidence bundles with manifest + hashing
Workflow-as-Code: Mission Spec v1 declarative YAML
Multi-Agent Orchestration: Foreman → specialist delegation

Bob's Multi-Department Architecture

Bob is the global orchestrator that coordinates multiple specialist departments. This repo contains Bob's first specialist team – the iam- department* (Intent Agent Model) – focused exclusively on ADK/Vertex compliance:

This repo = Bob's first specialist department, not Bob's entire brain.

Why This Team Exists

Building with Google ADK and Vertex AI requires strict architectural patterns. Most teams drift over time:

❌ Mix LangChain with ADK code
❌ Self-host runners instead of using Agent Engine
❌ Scatter docs across wikis and random files
❌ Skip memory wiring or do it incorrectly
❌ Violate Google's recommended patterns

This team prevents that drift. It audits your repos, detects violations, constructs fixes, and keeps you aligned with Google's ADK/Vertex standards.

What Makes It "Hard Mode"

We enforce 8 architectural rules (R1-R8) that prevent the usual agent chaos:

✅ ADK-only - No mixing LangChain, CrewAI, or other frameworks
✅ Managed runtime - Vertex AI Agent Engine, not self-hosted containers
✅ CI-enforced - Automated checks block bad patterns before they merge
✅ Memory that works - Dual Session + Memory Bank for real continuity
✅ Clean separation - Cloud Run proxies, not franken-servers with embedded agents
✅ One docs folder - All docs in 000-docs/, no scattered README files
✅ Immutable identity - SPIFFE IDs everywhere for clean tracing
✅ Drift detection - CI fails if you try to sneak in forbidden imports

Tl;dr: Production-grade multi-agent system with enforced architectural standards and compliance automation.

Key principle: Cloud Run services are proxies only. They forward requests to Agent Engine via REST. No Runner imports allowed in gateways.

⚡️ Hard Mode Explained

"Hard Mode" means we enforce strict rules that keep this agent system maintainable as it scales. This repository follows the ADK/Agent Engine Specification as its guiding architectural standard. Here's what that looks like:

The 8 Rules (R1-R8)

Every rule is enforced in CI. Violations fail the build automatically.

R1: Agent Implementation

✅ Use google-adk LlmAgent
❌ No LangChain, CrewAI, AutoGen, or custom frameworks

Why: Mixing frameworks creates integration nightmares. Pick one, stick with it.

R2: Deployed Runtime

✅ Deploy to Vertex AI Agent Engine
❌ No self-hosted runners or Cloud Run with embedded Runner

Why: Let Google manage the runtime. Focus on agent logic, not infrastructure.

R3: Gateway Separation

✅ Cloud Run as HTTP proxy to Agent Engine
❌ No Runner imports in gateway code

Why: Clean separation means gateways can restart without touching agents.

R4: CI-Only Deployments

✅ All deploys via GitHub Actions + Workload Identity Federation
❌ No manual gcloud deploy or service account keys

Why: Reproducible deployments. No "works on my machine" excuses.

R5: Dual Memory Wiring

✅ VertexAiSessionService + VertexAiMemoryBankService
✅ after_agent_callback to persist sessions

Why: Actual conversation continuity, not just storing embeddings.

R6: Single Docs Folder

✅ All docs in 000-docs/ with NNN-CC-ABCD-name.md format
❌ No scattered docs, multiple doc folders, or random READMEs

Why: Predictable structure. Easy to find things. Easy to copy to new repos.

R7: SPIFFE Identity

✅ spiffe://intent.solutions/agent/bobs-brain/<env>/<region>/<version>
✅ Propagated in AgentCard, logs, HTTP headers

Why: Immutable identity makes tracing and security audits straightforward.

R8: Drift Detection

✅ scripts/ci/check_nodrift.sh runs first in CI
❌ Blocks alternative frameworks, Runner in gateways, local creds

Why: Prevent architectural decay before it gets committed.

Enforcement

The drift check script (scripts/ci/check_nodrift.sh) runs before anything else in CI:

# .github/workflows/ci.yml
jobs:
  drift-check:
    runs-on: ubuntu-latest
    steps:
      - name: Check for drift violations
        run: bash scripts/ci/check_nodrift.sh
        # Fails build if violations found

If drift check fails, the entire pipeline stops. No tests run. No deployment happens. Fix the violations first.

🚀 Quick Start

Prerequisites

Python 3.12+
Google Cloud account with Vertex AI enabled
(Optional) Slack workspace for integration
(Optional) GitHub account for CI/CD

1. Clone & Setup

# Get the code
git clone https://github.com/intent-solutions-io/bobs-brain.git
cd bobs-brain

# Set up Python environment
python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

# Configure your environment
cp .env.example .env
# Edit .env with your GCP project details

2. Verify Everything Works

# Check all imports are valid
python3 -c "
from google.adk.agents import LlmAgent
from google.adk import Runner
from google.adk.sessions import VertexAiSessionService
from google.adk.memory import VertexAiMemoryBankService
from a2a.types import AgentCard
print('✅ All ADK imports working')
"

# Run drift detection locally
bash scripts/ci/check_nodrift.sh

3. Deploy (CI Recommended)

Option A: Via GitHub Actions (Recommended)

# Push to main triggers automatic deployment
git add .
git commit -m "feat: your feature description"
git push origin main

# GitHub Actions handles:
# 1. Drift detection
# 2. Tests
# 3. Docker build
# 4. Deploy to Agent Engine
# 5. Deploy gateways

Option B: Manual (Local Testing Only)

# This is for local development only
# Production deployments MUST go through CI
cd agents/bob
python3 -c "from agent import create_agent; a = create_agent(); print('✅ Agent created')"

4. Run Portfolio Audits

# Audit all local repos
python3 scripts/run_portfolio_swe.py

# Audit specific repos
python3 scripts/run_portfolio_swe.py --repos bobs-brain,diagnosticpro

# Export results
python3 scripts/run_portfolio_swe.py --output audit.json --markdown report.md

That's it. You've got a working AI agent that can audit code, fix issues, and generate docs.

📦 Portfolio Multi-Repo Audits

One of Bob's superpowers: auditing multiple repos at once and giving you org-wide metrics.

How It Works

Define your repos in config/repos.yaml:

repos:
  - id: bobs-brain
    display_name: "Bob's Brain"
    local_path: "."
    tags: ["adk", "agents", "production"]
    slack_channel: "#bobs-brain-alerts"

  - id: diagnosticpro
    display_name: "DiagnosticPro"
    local_path: "external"  # Not checked out locally (skipped gracefully)
    tags: ["production", "firebase"]

Run the portfolio orchestrator:

python3 scripts/run_portfolio_swe.py

Get aggregated results:

{
  "portfolio_run_id": "c98cc8f2-...",
  "timestamp": "2025-11-20T03:52:34Z",
  "summary": {
    "total_repos_analyzed": 5,
    "total_issues_found": 42,
    "total_issues_fixed": 30,
    "fix_rate": 71.4
  },
  "issues_by_severity": {
    "high": 5,
    "medium": 20,
    "low": 17
  },
  "repos": [...]
}

CLI Options

# Basic usage
python3 scripts/run_portfolio_swe.py

# Specific repos only
python3 scripts/run_portfolio_swe.py --repos bobs-brain,diagnosticpro

# Filter by tags
python3 scripts/run_portfolio_swe.py --tag production

# Different modes
python3 scripts/run_portfolio_swe.py --mode preview   # Read-only analysis
python3 scripts/run_portfolio_swe.py --mode dry-run   # Show what would change
python3 scripts/run_portfolio_swe.py --mode create    # Actually fix issues

# Export results
python3 scripts/run_portfolio_swe.py --output results.json --markdown report.md

Automated CI/CD Integration

The portfolio audit runs nightly via GitHub Actions:

# Manual trigger
gh workflow run portfolio-swe.yml \
  --ref main \
  --field repos=all \
  --field mode=preview

Features:

✅ Multi-repo ARV checks
✅ Automated audits (nightly at 2 AM UTC)
✅ JSON/Markdown export
✅ GCS storage for historical results (v2.1.5+)
📐 Slack notifications (coming soon)
📐 GitHub issue creation (coming soon)

Roadmap:

LIVE1-GCS (v2.1.5): ✅ Complete - GCS org-wide storage
LIVE-BQ (Future): BigQuery analytics integration
LIVE2 (Planned): Vertex AI Search RAG + Agent Engine calls (dev-only)
LIVE3 (Planned): Slack notifications + GitHub issue creation

🗄️ Org-Wide Storage

New in v2.1.5 - All your portfolio audit results stored in one place for easy querying and analytics.

What It Does

Centralized GCS bucket for all audit results
Lifecycle management (90-day retention for per-repo details)
Graceful fallback (writes never crash your pipeline)
Environment-aware (separate buckets for dev/staging/prod)

GCS Bucket Structure

gs://intent-org-knowledge-hub-{env}/
├── portfolio/runs/{run_id}/summary.json        # Portfolio-level summary
├── portfolio/runs/{run_id}/per-repo/*.json     # Per-repo details
├── swe/agents/{agent}/runs/{run_id}.json       # Single-repo runs (future)
├── docs/                                        # Org docs (future)
└── vertex-search/                               # RAG snapshots (LIVE2+)

Setup

1. Enable in Terraform:

# infra/terraform/envs/dev.tfvars
org_storage_enabled     = true
org_storage_bucket_name = "intent-org-knowledge-hub-dev"

2. Check readiness:

python3 scripts/check_org_storage_readiness.py
python3 scripts/check_org_storage_readiness.py --write-test

3. Enable writes:

export ORG_STORAGE_WRITE_ENABLED=true
export ORG_STORAGE_BUCKET=intent-org-knowledge-hub-dev

4. Run audit:

python3 scripts/run_portfolio_swe.py
# Results automatically written to GCS

Key Features

✅ Opt-in by default - Nothing writes unless you explicitly enable it
✅ Graceful errors - If GCS fails, pipeline continues (just logs error)
✅ Fully tested - 36 tests with 100% pass rate
✅ IAM-secured - Service account-based access control

That's the foundational Hard Mode architecture. Bob extends it into a full multi-agent department.

🚀 Deployment to Vertex AI Agent Engine

Bob deploys to Vertex AI Agent Engine using ADK CLI with full CI/CD automation.

Deployment Architecture

GitHub Actions (WIF)
    ↓
ADK CLI (adk deploy agent_engine)
    ↓
Vertex AI Agent Engine ← Managed runtime
    ↑
Cloud Run Gateways (A2A + Slack) ← HTTP proxies only

Prerequisites

Before deploying:

✅ GCP project with Vertex AI enabled
✅ GitHub secrets configured (WIF provider, service account)
✅ Terraform infrastructure applied (infra/terraform/)
✅ Staging bucket created (gs://<project-id>-adk-staging)

CI/CD Deployment (Recommended)

# Push to main triggers automatic deployment
git push origin main

# GitHub Actions automatically:
# 1. Runs drift detection (blocks if violations)
# 2. Runs tests
# 3. Authenticates via WIF (no keys!)
# 4. Builds Docker container
# 5. Deploys to Agent Engine
# 6. Deploys Cloud Run gateways

Terraform Infrastructure Deployment (R4-Compliant)

All infrastructure (including Slack gateway) is deployed via Terraform only:

# ⚠️ NEVER use manual gcloud commands for Slack Bob
# ❌ WRONG: gcloud run services update slack-webhook ...
# ✅ CORRECT: Use Terraform + GitHub Actions

# Deploy via GitHub Actions (RECOMMENDED):
# 1. Update Terraform code in infra/terraform/
# 2. Create PR → terraform plan runs automatically
# 3. Merge PR to main
# 4. Trigger workflow: .github/workflows/terraform-prod.yml
#    - Set apply=true for production deployment

Local Terraform Testing (Validation Only):

# Validate Terraform changes locally (no apply)
cd infra/terraform
terraform init -backend-config="bucket=bobs-brain-terraform-state"
terraform validate
terraform plan -var-file=envs/prod.tfvars

# ⚠️ NEVER run terraform apply locally for production
# Always use GitHub Actions for actual deployments

Important: R4 enforces CI-only deployments. Manual gcloud or local terraform apply commands create deployment drift and violate Hard Mode rules.

💬 Slack Integration

Bob communicates via Slack through an R3-compliant Cloud Run gateway that proxies to Agent Engine.

Architecture

Slack Events API
    ↓
Cloud Run: slack-webhook (R3 gateway - HTTP proxy only)
    ├─ Verifies Slack signature
    ├─ Transforms to Agent Engine format
    └─ POST /reasoningEngines/{id}:query
        ↓
Vertex AI Agent Engine: Bob
    ├─ ADK agent (google-adk)
    ├─ Dual Memory (Session + Memory Bank)
    └─ Returns response
        ↓
Cloud Run: slack-webhook
    └─ Formats response for Slack

Deployment (R4-Compliant)

✅ Correct Method:

# Use Terraform + GitHub Actions workflow
# Workflow: .github/workflows/terraform-prod.yml
# Module: infra/terraform/modules/slack_bob_gateway/

❌ DEPRECATED - DO NOT USE (R4 Violations):

# ⛔ THESE COMMANDS ARE BANNED - R4 HARD MODE VIOLATION
# Manual deployments create drift and violate CI-only deployment rules

# NEVER USE THESE:
gcloud run services update slack-webhook ...  # R4 VIOLATION - Use Terraform
gcloud run deploy slack-webhook --source .    # R4 VIOLATION - Use Terraform

# ⚠️  Using these commands will:
# - Create configuration drift (dev != prod)
# - Bypass CI quality gates (drift detection, ARV, tests)
# - Leave orphaned resources (service accounts, secrets)
# - Violate audit trail requirements
# - Block future Terraform deploys (state mismatch)

# ✅ CORRECT METHOD: See above - Use Terraform + GitHub Actions workflow

Configuration:

Secrets: Stored in Secret Manager (slack-bot-token, slack-signing-secret)
Feature Flag: slack_bob_enabled = true in envs/prod.tfvars
Environment: SLACK_BOB_ENABLED=true set by Terraform module

Terraform Variables

In infra/terraform/envs/{env}.tfvars:

project_id = "your-gcp-project"
location   = "us-central1"

# Org Storage
org_storage_enabled     = true
org_storage_bucket_name = "intent-org-knowledge-hub-dev"

# Agent Engine
agent_engine_id   = "bobs-brain-dev"
agent_runtime_sa  = "bob-agent-dev@your-project.iam.gserviceaccount.com"

🚨 Troubleshooting

Drift Detection Failed

Symptom: CI fails with "Drift violations detected"

Fix:

# Run locally to see violations
bash scripts/ci/check_nodrift.sh

# Common issues:
# 1. Imported Runner in service/ → Remove it, use REST API
# 2. Found LangChain/CrewAI → Remove alternative frameworks
# 3. Service account keys in repo → Remove, use WIF

Agent Can't Find ADK Docs

Symptom: Agent says "I don't have information about that ADK pattern"

Fix:

# Set up Vertex AI Search
bash scripts/deployment/setup_vertex_search.sh

# Check datastore exists
export VERTEX_SEARCH_DATASTORE_ID=adk-documentation

Org Storage Not Writing

Symptom: Portfolio audit runs but no GCS files appear

Fix:

# Check readiness
python3 scripts/check_org_storage_readiness.py --write-test

# Common issues:
# 1. ORG_STORAGE_WRITE_ENABLED not set → export ORG_STORAGE_WRITE_ENABLED=true
# 2. Bucket doesn't exist → Apply Terraform with org_storage_enabled=true
# 3. No IAM permissions → Add service account to org_storage_writer_service_accounts

Deploy Failed: Agent Engine Not Found

Symptom: adk deploy fails with "Agent Engine not found"

Fix:

# Create infrastructure first
cd infra/terraform
terraform init
terraform plan -var-file=envs/dev.tfvars
terraform apply -var-file=envs/dev.tfvars

# Verify engine exists
gcloud ai agent-engines list --region=us-central1

📊 Project Status

Current Version: v2.1.5 – Vision Alignment GA (Enterprise Controls + ADK Compliance Department)

What's New in v2.1.5:

✅ Canonical Agent IDs: bob, iam-orchestrator, iam-compliance, etc. with backwards-compatible aliases
✅ Enterprise Controls: Risk tiers R0-R4, policy gates, tool allowlists
✅ Evidence Bundles: Complete audit trails with manifest + hashing
✅ Mission Spec v1: Declarative workflow-as-code in YAML
✅ 370+ unit tests: Comprehensive coverage

Deployment Status:

✅ Agent Engine: All 10 Hard Mode agents deployed
✅ A2A Protocol: Foreman + workers architecture live
✅ Inline Source Deployment: Complete with ARV gates and CI workflows

Key Capabilities:

✅ Canonical agent identity system with alias support
✅ Enterprise controls (R0-R4 risk tiers, policy gates)
✅ Mission Spec v1 (declarative workflows)
✅ Evidence bundles for audit trails
✅ MCP Server with 8 tools (code search, file access, pattern checking)
✅ 8 specialist agents (iam-compliance, iam-triage, iam-planner, etc.)
✅ Canonical doc suite (28 standards, now 000-* prefix)

Standards (v2.1.5):

252-DR-STND-agent-identity-standard.md - Canonical IDs
253-DR-STND-mandates-budgets-approvals.md - Enterprise controls
254-DR-STND-policy-gates-risk-tiers.md - R0-R4 enforcement
255-DR-STND-evidence-bundles-and-audit-export.md - Audit trails
257-DR-STND-mission-spec-v1.md - Workflow-as-code

Metrics:

370+ unit tests (100% pass)
30+ comprehensive docs
8 enforced Hard Mode rules (R1-R8)
15 CI checks
10 deployed agents

🔧 What Was Wrong and What We Fixed (v2.1.5)

Before Hard Mode, Bob's Brain had typical agent repo problems:

Problems:

❌ Mixed frameworks (ADK + LangChain + custom code)
❌ Self-hosted runners (containers that sometimes crashed)
❌ Manual deployments (inconsistent environments)
❌ Scattered docs (README, wiki, notion, random .md files)
❌ No drift detection (architectural decay over time)

Solutions (Hard Mode):

✅ R1-R8 rules enforced in CI
✅ Vertex AI Agent Engine (let Google manage runtime)
✅ GitHub Actions with WIF (reproducible deploys)
✅ Single 000-docs/ folder with filing system
✅ Automated drift checks block violations

Result: Agent system that's maintainable, scalable, and actually works in production.
