# Plan Review Loop Adversarial review loop for implementation plans, modeled on the review-loop plugin's implement → independent review → address cycle, but targeting **plans** instead of code. A plan defect costs an hour of review now or a day of wrong implementation later. **Core principle:** A plan is only as good as its worst instruction executed by someone with zero context. Reviewers must never have seen the planning conversation — fresh context is the independence guarantee. ## Lifecycle ``` setup → locate-or-author → independent review → address with judgment → [confirm] → cleanup ``` State lives in `.claude/plan-review-loop.local.md`. Reviews are written to `reviews/plan-review-<id>.md`. On any tooling error, fail open: report the problem and continue without the loop rather than trapping the user. **Enforcement:** the inkstone stop hook (`hooks/stop-hook.sh`) will not let the session stop while this loop's state file says the review is incomplete, findings are undispositioned, or a required confirmation round is pending. Keep the state file's `phase:` accurate as you progress — it is the contract with the hook. **Coexistence with the original review-loop plugin:** the setup block below refuses to start while a code review loop (`.claude/review-loop.local.md`) is active, and the stop hook defers entirely to that plugin whenever its state file exists. Run doc loops and code loops sequentially, never concurrently. ## Phase 0 — Setup If the argument is `cancel`
