# /rpi - Full Lifecycle Orchestrator

> Quick ref: `/discovery` -> `/crank` -> `/validate`, then report.

**Execute this workflow. Do not only describe it.** RPI is autonomous unless
`--interactive` is set. The user touchpoint is after validation, or after a
real blocked state exhausts retries. Read
[references/autonomous-execution.md](references/autonomous-execution.md) when
you need the full autonomy contract.

## Loop position

`/rpi` is the orchestrator across **every move** of the [operating loop](../../docs/architecture/operating-loop.md): BDD intent → vertical slices → conflict-free wave → bead acceptance → evidence + learning capture. It delegates each move to the skill that owns it (`/discovery`, `/plan`, `/crank`, `/validate`, `/forge`/`/post-mortem`), and enforces three loop-level invariants:

- **No move-skipping.** Strict delegation is on by default; phases never compress, and validation cannot be skipped. The lifecycle objective is preserved across the whole loop.
- **The first failing test is the bead's contract.** With `--test-first` on (the default), `/crank` is invoked with the TDD-per-slice discipline; `--no-test-first` is an explicit opt-out, not a fast path.
- **Acceptance examples close the bead, not activity.** Validation FAIL re-cranks on the same objective up to 3 attempts; DONE requires the acceptance roll-up in the [slice-validation template](../../docs/templates/slice-validation.md) to be fully green.
- **Ports stay visible.** Preserve the
  [Intent-to-Loop Hexagon](../../docs/architecture/intent-to-loop-hexagon.md)
  boundary as the objective crosses `shape_intent`, `persist_intent`,
  `plan_slices`, `execute_wave`, `validate_acceptance`, and `record_evidence`.
- **Context density survives phase boundaries.** Apply the [Context Density Rule](../domain/references/context-density-rule.md) to every phase handoff and final report: keep intent, boundary, evidence, decision, constraint, and next action; omit or link anything else.

## Core Contract

RPI delegates via `Skill(skill="discovery", ...)`,
`Skill(skill="crank", ...)`, and `Skill(skill="validate", ...)` as separate
tool invocations. Keep strict delegation on by default; do not compress phases,
replace phase skills with direct agent spawns, or skip validation. Read
[../shared/references/strict-delegation-contract.md](../shared/references/strict-delegation-contract.md)
for the full anti-compression contract.
See [references/isolation-contract.md](references/isolation-contract.md) for
the four-lever model, phase-isolated skill transport, and the compression
patterns `scripts/check-skill-isolation.sh` flags. See
[references/best-practices.md](references/best-practices.md) for the principle
and anti-pattern citation table.

When the runtime supports phase isolation, keep `/rpi` visible in the main
session and run each phase contract through isolated transport: phase skill
name in, bounded handoff artifact in, phase artifact/verdict/next action out.
The transport may be a daemon job, process runner, or subagent wrapper, but it
must execute the declared phase skill contract rather than doing phase work
directly.

RPI owns one lifecycle objective across all phases. Preserve the discovered
`epic_id` when present; otherwise preserve the original goal and execution
packet objective. A child bead or one ready slice is context, not a replacement
objective. `<promise>PARTIAL</promise>` from `/crank` means retry Phase 2 on the
same objective.

## Route And Classify

1. Create `.agents/rpi/`.
2. Resolve `--from`:
   - default, `research`, `plan`, `pre-mortem`, `brainstorm` -> discovery
   - `implementation` or `crank` -> implementation
   - `validation`, `vibe`, or `post-mortem` -> validation
3. If the input is a bead and `--from` is absent, resolve it with `bd show`:
   - epic -> implementation with that epic
   - child with parent -> implementation with the parent epic
4. Classify complexity:
   - `fast`: short/simple goal or `--fast-path`
   - `standard`: medium goal or one scope keyword
   - `full`: `--deep`, complex-operation keyword, 2+ scope keywords, or >120 chars
5. Log `RPI mode: rpi-phased (complexity: <level>)`.

Track state compactly:

```text
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,
  verdicts: {}
}
```

Complex-operation keywords include `refactor`, `migrate`, `rewrite`,
`redesign`, `rearchitect`, `overhaul`, `decouple`, `deprecate`, `split`,
`extract module`, and `port`. Scope keywords include `all`, `entire`, `across`,
`everywhere`, `every file`, `system-wide`, `global`, and `codebase`.

## Phase DAG

Enter at the routed phase and run every phase after it.

1. **Discovery:** invoke `/discovery <goal> [--interactive] --complexity=<level>`
   directly or through phase-isolated skill transport.
   On DONE, read `.agents/rpi/execution-packet.json` or the run archive and
   preserve its objective spine. On BLOCKED, stop with the discovery verdict.
2. **Implementation:** invoke `/crank <epic-id>` when the packet has `epic_id`;
   otherwise invoke `/crank .agents/rpi/execution-packet.json`, directly or
   through phase-isolated skill transport. Pass `--test-first` or
   `--no-test-first` through. On DONE, record `ao ratchet record implement
   2>/dev/null || true` and continue. On PARTIAL or BLOCKED, retry the same
   objective up to 3 total attempts.
3. **Validation:** invoke `/validate <epic-id> --complexity=<level>` when an
   epic exists; otherwise invoke `/validate --complexity=<level>`, directly
   or through phase-isolated skill transport. Add `--strict-surfaces` when
   `--quality` is set. On FAIL, extract findings, re-run `/crank` on the same
   objective, then re-run `/validate`, up to 3 total validation attempts. On
   DONE, record `ao ratchet record vibe 2>/dev/null || true`.
4. **Report:** summarize phase verdicts and ep
