Ralph is a PRD-driven persistence loop that keeps working on a task until ALL user stories have passes: true and are reviewer-verified.

When to Use

Task requires guaranteed completion with verification
Work may span multiple iterations and needs persistence
Task benefits from structured PRD-driven execution

When NOT to Use

Full autonomous pipeline → use /omg-autopilot
Explore or plan before committing → use /plan
Quick one-shot fix → delegate to @executor

Flags

--no-prd: Skip PRD generation, work in legacy mode (for trivial fixes)
--no-deslop: Skip the mandatory post-review cleanup pass

Steps

1. PRD Setup (first iteration)

Check if .omc/prd.json exists via omg_read_prd
If none exists, generate a PRD scaffold with task-specific acceptance criteria
CRITICAL: Replace generic criteria with specific, testable ones
Initialize progress tracking

2. Pick Next Story

Read PRD via omg_read_prd
Select highest-priority story with passes: false

3. Implement Current Story

Delegate to @executor at appropriate complexity level
If sub-tasks are discovered, add as new stories to PRD

4. Verify Acceptance Criteria

For EACH criterion, verify with fresh evidence
Run relevant checks (test, build, lint, typecheck)
If any criterion NOT met, continue working

5. Mark Story Complete

Set passes: true via omg_update_story
Record progress in progress.txt

6. Check PRD Completion

Call omg_check_completion
If NOT all complete, loop to Step 2
If ALL complete, proceed to verification

7. Reviewer Verification

@verifier checks against specific acceptance criteria from PRD
@architect reviews for architectural soundness

7.5 Mandatory Cleanup Pass

Unless --no-deslop, run /ai-slop-cleaner on changed files only

7.6 Regression Re-verification

Re-run all tests after cleanup pass
Only proceed after regression tests pass

8. Completion

On approval: run /cancel for clean exit
On rejection: fix issues, re-verify, loop back

Execution Policy

Fire independent tasks simultaneously
Run builds/tests in background
Deliver full implementation: no scope reduction, no partial completion
