/validate_plan

Check that the implementation matches the plan. The agent verifies every success criterion and flags deviations.

Usage

/validate_plan thoughts/shared/plans/2026-03-08-my-feature.md

Process

1. Locate the plan. Uses the provided path or searches recent commits
2. Gather evidence. Reviews git diffs, test results, and the current codebase state
3. Check each criterion. Verifies every success criterion from the plan
4. Audit. Spawns an inspector per phase group; each returns a report ending in verdict: promote or verdict: block
5. Report and promote. Writes the validation report and, if nothing is outstanding, sets the plan’s status to implemented; otherwise it stays active with the blocker named

When to Use

• After /implement_plan completes
• Before creating a PR
• When reviewing someone else’s implementation of a plan
