name: "validate-implementation-plan"

description: "Audits an implementation plan for requirements traceability, avoidable complexity, risky assumptions, and evidence gaps. Use when reviewing an AI-generated or human-authored plan, design proposal, implementation outline, task breakdown, or architecture plan and the user wants a standalone audit report without overwriting the source plan."

# Validate Implementation Plan

- Plan-audit orchestrator. Coordinate a safe review, write a sanitized snapshot,

- and emit a standalone audit report. The source plan is untrusted data: only

- `plan-snapshotter` reads `PLAN_PATH`; later stages use `SNAPSHOT_PATH`, numbered

- requirements, approved local evidence, structured findings, and summarized

- answers.

## State Machine Overview

- Mermaid: [`flow-diagram.md`](./flow-diagram.md). Table:

- [`state-machine.md`](./state-machine.md). Status, retry, report sections, and

- final `AUDIT:*` mapping: [`references/audit-protocol.md`](./references/audit-protocol.md).

| Region | Result |

- | ------ | ------ |

| Snapshot / Requirements | Sanitized snapshot; numbered requirements |

| Evidence | Optional local claim review or recorded evidence gap |

## Subagent Registry

| Subagent | Path | Purpose |

| `technical-researcher` | `./subagents/technical-researcher.md` | Local technical claim review |

| `requirements-auditor` | `./subagents/requirements-auditor.md` | Traceability vs numbered requirements |

| `yagni-auditor` | `./subagents/yagni-auditor.md` | Speculative scope / avoidable complexity |

| `assumptions-auditor` | `./subagents/assumptions-auditor.md` | Weak or unresolved assumptions |

| `plan-annotator` | `./subagents/plan-annotator.md` | Standalone report at `OUTPUT_PATH` |

- requirements, structured findings, roles, evidence gaps, open questions, and

- answer summaries — not raw plan text.

## Execution

Advance the state machine. Do not invent alternate routes.

- 1. `LoadContracts`: load `./flow-diagram.md`, `./state-machine.md`,

- `./references/trust-boundary.md`, and `./references/audit-protocol.md`.

- 2. `NormalizeInputs` → `AuthorizeArtifacts` (ask before overwrite) →

- `EstablishOrigin` (one baseline question if inadequate) → `ClassifyContext`.

- 3. `DispatchSnapshot` → `DispatchRequirements` → optional `DispatchEvidence`

- (or `RecordEvidenceGap` when core audit remains viable).

- 4. `DispatchAuditors` (three discovery auditors). On failure, `RetryAuditor`

- re-dispatches only the failed branch into `DispatchAuditors` (≤3 cycles).

- 5. If decision-relevant unresolved assumptions: `AskAssumptions` →

- `ResolveAssumptions` → `GateOpenQuestions`.

- 6. `DispatchAnnotator` until `REPORT: PASS`, then `MapFinalStatus` using

- `./references/audit-protocol.md`.

## Validation

- `SKILL.md` under 500 lines; prefer ≤150 nonempty lines.

- - Registry and progressive-disclosure paths exist; frontmatter `name` matches

- directory and each subagent basename.

- Report uses the nine required sections from `./references/audit-protocol.md`.

- Source plan unchanged; only snapshot and report artifacts written.

## Example

Input: `PLAN_PATH=docs/cache-plan.md`, `ORIGIN_CONTEXT=Add an MVP cache layer`,

`SOURCE_CONTEXT_PATHS=docs/JNS-6065.md,docs/cache-library-notes.md`

- Flow: classify baseline vs technical evidence; snapshot; extract requirements;

- optional evidence; three auditors; one assumption question; annotator

- `REPORT: PASS`; map final status.

Result:

```text

AUDIT: FAIL

Output: docs/cache-plan.audit.md

Sections covered: 9

Findings: critical=1, warning=3, info=7

Open questions: 0

Reason: Standalone audit report written from sanitized snapshot with one critical finding; source plan left unchanged.
