Ralph Autonomous Agent

Orchestrates autonomous code generation through repeated iterations using fresh agent instances until all tasks are complete.

Execution Contract

Inputs

When invoking ralph, provide:

• •Plan file path: Absolute or workspace-relative path to the plan markdown file
• •Starting task (optional): Task ID to resume from (e.g., "Task 3")
• •Max iterations (optional): Default 20

State Files

Ralph creates a companion progress file alongside the plan:

.agents/plans/in-progress/
├── my-feature.md              # The plan
└── my-feature.progress.md     # Progress log (auto-created)

Task Status Markers

In plan files, tasks use checkbox status with optional annotations:

Stop Conditions

The loop exits when ANY of these occur:

1. •All tasks complete: Every task checkbox is [x]
2. •Blocked encountered: A task is marked (blocked)
3. •Max iterations reached: Default 20 iterations
4. •Only manual-verify remaining: All incomplete tasks require manual verification
5. •Explicit stop: User interrupts

Handoff Payload

When handing off to fresh iteration, include:

Continue ralph execution for: [plan file path]

Current task: [Task ID and title]
Last progress: [Most recent progress entry summary]
Next action: [Specific next step]

Load the ralph skill and continue execution.

Phases

Phase 1: Setup

Before running the loop, ensure the plan has proper structure.

Required task format:

- [ ] **Task N: Short descriptive title**
  - Scope: `path/to/affected/files` or package name
  - Depends on: Task M (or "none")
  - Acceptance:
    - Specific criterion 1
    - Specific criterion 2
  - Notes: Optional implementation hints

Task sizing rule: If you can't describe the task in 2-3 sentences, it's too big. Split it.

Dependency ordering: Schema → Service → API → UI → Tests

Phase 2: Execution Loop

Each iteration follows this workflow:

1. •Load context: Read plan file, identify next incomplete task
2. •Check dependencies: Ensure all Depends on tasks are complete
3. •Implement: Complete the task following its scope and acceptance criteria
4. •Verify: Run verification commands (see Verification section)
5. •Update progress: Append entry to .progress.md
6. •Update plan: Check off completed task [x]
7. •Commit: One task = one commit with proper footers
8. •Handoff or complete: Continue to next task or exit if done

Git discipline:

• •One task = one commit
• •Never push to main branch
• •Include footers: Amp-Thread-ID and Co-authored-by: Amp <amp@ampcode.com>
• •Commit format: feat: [Task ID] - [Task Title]

Verification Strategy

Run verification commands appropriate for the project. Check AGENTS.md for project-specific commands.

Examples by language:

# TypeScript/Node
npm run check && npm run lint && npm test

# Rust
cargo check && cargo clippy && cargo test

# Go
go build ./... && go test ./...

# Python
mypy . && ruff check . && pytest

Stuck Detection & Safety

Limits

• •Max iterations: 20 per session
• •Max retries per task: 2 attempts before marking blocked
• •Scope control: Only modify files in declared Scope

Blocking a Task

When a task cannot proceed:

1. •Add (blocked) annotation to the task checkbox
2. •Add blocker details to progress file
3. •Stop the loop and surface to user

Example blocked task:

- [ ] (blocked) **Task 5: Integrate payment API**
  - Scope: `cloud/functions/payments`
  - Depends on: Task 4
  - Acceptance: Payment webhook handler works
  - Notes: Blocked - need API credentials from finance team

Manual Verification Tasks

Tasks marked (manual-verify) require human interaction:

• •Don't retry these automatically
• •Stop loop when only manual-verify tasks remain
• •Surface verification instructions to user

Guardrails

1. •Scope control: Only touch files in declared Scope
2. •No scope creep: Expanding scope requires explicit plan edit
3. •No prod commands: Never run production deployments
4. •No secrets: Never commit credentials or API keys
5. •Branch safety: Never push to main

Usage

Starting Fresh

Run ralph on .agents/plans/tech-debt/in-progress/my-feature.md

Resuming

Continue ralph from Task 5 on .agents/plans/tech-debt/in-progress/my-feature.md

Checking Status

Show ralph progress for .agents/plans/tech-debt/in-progress/my-feature.md

Integration with Plans

Ralph works with plans in the standard directory structure:

• •Plans live in .agents/plans/in-progress/
• •Create plans manually following the task format above
• •Use ralph to execute plans autonomously
