Rpi

/rpi — Full RPI Lifecycle Orchestrator

Quick Ref: One command, full lifecycle. /discovery → /crank → /validation. Thin wrapper that delegates to phase orchestrators.

YOU MUST EXECUTE THIS WORKFLOW. Do not just describe it.

Quick Start

/rpi "add user authentication"                        # full lifecycle
/rpi --interactive "add user authentication"          # human gates in discovery only
/rpi --from=discovery "add auth"                      # resume discovery
/rpi --from=implementation ag-23k                      # skip to crank with existing epic
/rpi --from=validation                                 # run validation only
/rpi --loop --max-cycles=3 "add auth"                 # iterate-on-fail loop
/rpi --deep "refactor payment module"                  # force full council ceremony
/rpi --fast-path "fix typo in readme"                  # force lightweight ceremony
/rpi --no-test-first "add auth"                       # opt out of strict-quality

Phase orchestrators own all sub-skill sequencing, retry gates, and phase budgets. /rpi owns only: setup, complexity classification, phase routing, implementation gate, validation-fail-to-crank loop, and final report.

Execution Steps

Step 0: Setup + Classify

mkdir -p .agents/rpi

Determine starting phase:

• default: discovery
• --from=implementation (aliases: crank) → skip to Phase 2
• --from=validation (aliases: vibe, post-mortem) → skip to Phase 3
• aliases research, plan, pre-mortem, brainstorm map to discovery
• If input looks like an epic ID (ag-*) and --from is not set, start at implementation.

Classify complexity:

Complex-operation keywords: refactor, migrate, migration, rewrite, redesign, rearchitect, overhaul, restructure, reorganize, decouple, deprecate, split, extract module, port

Scope keywords: all, entire, across, everywhere, every file, every module, system-wide, global, throughout, codebase

Overrides: --deep forces full. --fast-path forces fast.

Log:

RPI mode: rpi-phased (complexity: <level>)

Initialize state:

rpi_state = {
  goal: "<goal string>",
  epic_id: null,
  phase: "<discovery|implementation|validation>",
  complexity: "<fast|standard|full>",
  test_first: <true by default; false only when --no-test-first>,
  cycle: 1,
  max_cycles: <3 when --loop; overridden by --max-cycles>,
  verdicts: {}
}

Phase 1: Discovery

Delegate to /discovery:

Skill(skill="discovery", args="<goal> [--interactive] --complexity=<level>")

After /discovery completes:

1. Check completion marker: <promise>DONE</promise> or <promise>BLOCKED</promise>
2. If BLOCKED: stop. Discovery handles its own retries (max 3 pre-mortem attempts). Manual intervention needed.
3. If DONE: extract epic-id from .agents/rpi/execution-packet.json
4. Store rpi_state.epic_id and rpi_state.verdicts.pre_mortem

Phase 2: Implementation

Requires rpi_state.epic_id.

Skill(skill="crank", args="<epic-id> [--test-first] [--no-test-first]")

Implementation gate (max 3 attempts):

• <promise>DONE</promise>: proceed to validation
• <promise>BLOCKED</promise>: retry with block context (max 2 retries)
  • Re-invoke /crank with epic-id + block reason
  • If still BLOCKED after 3 total: stop, manual intervention needed
• <promise>PARTIAL</promise>: retry remaining (max 2 retries)
  • Re-invoke /crank with epic-id (picks up unclosed issues)
  • If still PARTIAL after 3 total: stop, manual intervention needed

Record:

ao ratchet record implement 2>/dev/null || true

Phase 3: Validation

Skip if: complexity == fast (fast-path runs discovery + crank only).

Skill(skill="validation", args="<epic-id> --complexity=<level>")

Validation-to-crank loop (max 3 total attempts):

• <promise>DONE</promise>: finish RPI
• <promise>FAIL</promise>: vibe found defects
  1. Extract findings from validation output
  2. Re-invoke /crank with epic-id + findings context (preserve --test-first / --no-test-first from original invocation)
  3. Re-invoke /validation
  4. If still FAIL after 3 total: stop, manual intervention needed

Record:

ao ratchet record vibe 2>/dev/null || true

Step Final: Report + Loop

Report: Summarize all phase verdicts and epic status.

Optional loop (--loop): If validation verdict is FAIL and cycle < max_cycles:

1. Extract 3 concrete fixes from the post-mortem report
2. Increment rpi_state.cycle
3. Re-invoke /rpi from discovery with a tightened goal
4. PASS/WARN stops the loop

Optional spawn-next (--spawn-next): After PASS/WARN finish:

1. Read .agents/rpi/next-work.jsonl for harvested follow-up items
2. Report with suggested next /rpi command
3. Do NOT auto-invoke

Flags

Phase Data Contracts

All transitions use filesystem artifacts (no in-memory coupling). The execution packet (.agents/rpi/execution-packet.json) carries contract_surfaces (repo execution profile), done_criteria, and queue claim/finalize metadata between phases. Sub-skills include /plan, /vibe, /post-mortem, and /pre-mortem. For detailed contract schemas, read references/phase-data-contracts.md.

Complexity-Scaled Council Gates

Phase 3: Pre-mortem

• complexity == "low": inline review, no spawning (--quick)
• complexity == "medium": inline fast default (--quick)
• complexity == "high": full council, 2-judge minimum
• Retry gate: max 3 total attempts

Phase 5: Final Vibe

• complexity == "low": inline review, no spawning (--quick)
• complexity == "medium": inline fast default (--quick)
• complexity == "high": full council, 2-judge minimum
• Retry gate: max 3 total attempts

Phase 6: Post-mortem

• complexity == "low": inline review, no spawning (--quick)
• complexity == "medium": inline fast default (--quick)
• complexity == "high": full council, 2-judge minimum
• Retry gate: max 3 total attempts
