What problem does it solve? Teams using plan-driven development lack an automated way to verify that a pull request actually implements what its plan declared. This Skill runs a non-interactive implementation review inside GitHub Actions, comparing the PR diff against the plan's commitments and publishing an auditable verdict. ## Core Features & Use Cases - Plan Drift Detection: Discovers the plan file under context/changes/, cross-references changed files against planned files, and flags MATCH / DRIFT / MISSING / EXTRA per planned change. - Parallel Evidence Gathering: Spawns three subagents covering plan drift, safety/quality/pattern compliance, and test coverage, then runs the plan's non-test automated checks (lint, build, typecheck). - Auditable Output Contract: Writes a structured impl-review.md report with a seven-dimension verdict table, commits it to the PR branch with [skip ci], posts inline review comments on flagged diff lines, and publishes a summary PR comment. - Use Case: A team labels a PR with impl-review; the workflow reviews the PR against its plan, commits the report, and gates the merge on a REJECTED verdict unless an impl-review-override label is present. ## Quick Start Ask the agent to run the 10x-impl-review-ci skill on this pull request in GitHub Actions to review the implementation against its plan and post the verdict.
