How it works

Smart Ralph creates research, requirements, design, and task files before implementation. Large goals can start with triage, which splits the work into dependency-aware specs.

The spec files stay in the project, so you can review or edit each phase before execution. Smart Ralph records progress between tasks and can resume after a stopped session.

An optional prototype can test one focused design question without turning disposable source into production code.

Installation

Claude Code

/plugin marketplace add tzachbon/smart-ralph
/plugin install ralph-specum@smart-ralph

Restart Claude Code after installation.

Codex

codex plugin marketplace add tzachbon/smart-ralph \
  --sparse .agents/plugins \
  --sparse plugins/ralph-specum-codex
codex plugin add ralph-specum@smart-ralph

Start a new Codex task after installation. Run /hooks, review the bundled Stop hook, and trust it if you want automatic task execution. Until then, run $ralph-specum-implement once per task.

The Codex installation guide covers updates, local development with codex plugin marketplace add ., and migration from the old platforms/codex/ skills.

For local Claude Code development, clone this repository and run claude --plugin-dir ./plugins/ralph-specum.

Quick start

Codex

$ralph-specum-start user-auth "Add JWT authentication"

Use $ralph-specum when you want Smart Ralph to choose the next action. Codex asks for approval after each spec artifact unless the command includes the exact --quick flag. Start with $ralph-specum-triage when a goal spans several features or systems.

Claude Code

/ralph-specum:start user-auth "Add JWT authentication"

Add --quick to generate the spec and start execution without stopping between phases. Run /ralph-specum:start without arguments to resume the active spec.

Commands

Claude Code uses /ralph-specum:<name>. Codex uses $ralph-specum-<name> and folds new into $ralph-specum-start.

Command	What it does
/ralph-specum:start [name] [goal]	Resume a spec or create one
/ralph-specum:start [goal] --quick	Generate all spec phases and execute
/ralph-specum:new <name> [goal]	Create a spec and wait for approval before research
/ralph-specum:triage [name] [goal]	Split a large goal into an epic
/ralph-specum:research	Run or repeat research
/ralph-specum:requirements	Generate requirements from research
/ralph-specum:prototype	Run or resume an optional prototype
/ralph-specum:design	Generate the technical design
/ralph-specum:tasks	Break the design into executable tasks
/ralph-specum:implement	Execute tasks one at a time
/ralph-specum:index	Generate searchable codebase specs
/ralph-specum:refactor	Update requirements, design, or tasks
/ralph-specum:status	Show specs and progress
/ralph-specum:switch <name>	Change the active spec
/ralph-specum:cancel	Cancel execution and remove loop state
/ralph-specum:feedback [message]	Submit feedback or report an issue
/ralph-specum:help	Show command and workflow help

Execution model

Smart Ralph gives each phase to a focused agent.

Phase	Agent	Responsibility
Triage	triage-analyst	Split features and map dependencies
Research	research-analyst	Inspect the codebase and check feasibility
Requirements	product-manager	Write user stories and acceptance criteria
Prototype	prototype-builder	Test one design question with disposable evidence
Design	architect-reviewer	Define architecture and trade-offs
Tasks	task-planner	Create a POC-first task sequence
Execution	spec-executor	Implement tasks and run quality gates

Tasks follow four phases:

1. Make it work: validate the approach with a POC.
2. Refactoring: clean up the working implementation.
3. Testing: add unit, integration, and end-to-end coverage.
4. Quality gates: run lint, type, and CI checks.

Planning controls include:

• --tasks-size fine|coarse for task granularity
• [P] for low-conflict parallel tasks
• [VERIFY] and VE tasks for explicit verification
• approval checkpoints between spec phases outside quick mode

Optional prototypes

• In normal mode, Smart Ralph may suggest a prototype after research or requirements. You can also run /ralph-specum:prototype or $ralph-specum-prototype at a safe phase boundary.
• In quick mode, Smart Ralph asks no prototype questions, owns the decisions, and always continues to design after the prototype outcome.
• Prototype source stays in a sibling worktree or eligible scratch directory. Quick mode transfers no source into the current checkout; normal mode transfers only paths you approve.
• Reviewed terminal records are immutable. Local evidence does not authorize a push, remote branch, PR update, issue write, or record deletion.

Smart Ralph stores progress in .progress.md and marks completed work in tasks.md. Each implementation task starts with fresh context.

Codebase indexing

/ralph-specum:index scans an existing project and writes searchable component specs under specs/.index/. Research agents use that index to find code that the project already has.

/ralph-specum:index
/ralph-specum:index --quick
/ralph-specum:index --dry-run
/ralph-specum:index --path=src/api/

Option	Effect
--path=<dir>	Scan one directory
--type=<types>	Limit component types
--exclude=<patterns>	Skip matching paths
--dry-run	Preview without writing specs
--force	Regenerate the index
--changed	Regenerate Git-changed files
--quick	Skip the pre-scan and post-scan interviews

The scanner detects controllers, services, models, helpers, and migrations. It can also record external URLs, MCP servers, and installed skills. Run the index before starting a feature in a codebase that Smart Ralph has not seen.

The generated index has a summary dashboard, component specs, and external resource specs. Research searches both feature specs and indexed specs when it gathers context.

Project structure

Plugin source lives in plugins/ralph-specum/ for Claude Code, plugins/ralph-specum-codex/ for Codex, and plugins/ralph-speckit/ for the Spec-Kit workflow.

Smart Ralph writes feature specs inside the project where you run it:

specs/
|-- .current-spec
`-- my-feature/
    |-- .ralph-state.json
    |-- .progress.md
    |-- prototypes/
    |   `-- <id>.md
    |-- research.md
    |-- requirements.md
    |-- design.md
    `-- tasks.md

Smart Ralph deletes .ralph-state.json when execution finishes. It keeps .progress.md so later tasks can recover decisions and learnings.

Epic plans live under specs/_epics/<name>/. Their state files track which specs are ready, blocked, or complete.

Ralph Speckit

ralph-speckit is the alternative plugin for GitHub's Spec-Kit methodology. It adds a project constitution and requirement-to-task traceability.

Feature	ralph-specum	ralph-speckit
Directory	specs/	.specify/specs/
Naming	my-feature/	001-feature-name/
Governance	Per-spec workflow	Project constitution
Main files	Research, requirements, design, tasks	Spec, plan, tasks
Best fit	Fast iteration	Team governance and audit trails

/plugin install ralph-speckit@smart-ralph
/speckit:constitution
/speckit:start user-auth "Add JWT authentication"
/speckit:specify
/speckit:plan
/speckit:tasks
/speckit:implement

The plugin also includes /speckit:status, /speckit:switch, /speckit:cancel, /speckit:clarify, and /speckit:analyze. See the Ralph Speckit guide for its file layout and command details.

Troubleshooting

• Repeated task failure: read .progress.md, fix the reported problem, then run /ralph-specum:implement.
• Start over: run /ralph-specum:cancel, then start a new spec.
• Resume work: run /ralph-specum:start. Ralph finds the active spec.

See the Troubleshooting Guide for installation, state, hook, and recovery problems.

Upgrading

Smart Ralph v3.0.0 moved execution into the plugin's Stop hook. Projects that used v2.x no longer need the separate Ralph Loop plugin.

Update Smart Ralph, restart Claude Code, and resume. Existing spec files need no migration. You can uninstall Ralph Loop if no other workflow uses it. Check GitHub releases for later changes.

Contributing

PRs are welcome. Read CONTRIBUTING.md for setup, tests, and pull request guidance.

Credits

Smart Ralph takes its name from the Ralph agentic loop pattern and Springfield's most determined student. Ralph does the next task. Be like Ralph.

• Built for Claude Code and OpenAI Codex
• Inspired by developers who wanted their coding agent to handle the whole feature
