What problem does it solve? Turning an approved implementation plan into verified code changes is error-prone: plans go stale, steps get skipped, and reviewers cannot tell what actually happened. This Skill executes an existing agent-quorum plan step by step, preflights every referenced file and symbol, runs the right verification commands, and records only deviations and issues in a lightweight journal. ## Core Features & Use Cases - Plan preflight and execution: Resolves a markdown plan or a plan.package/ directory, verifies every referenced file, symbol, and command exists, then implements each phase using repository entry points like pnpm run check. - Deviation journaling: Writes a terse journal under .agents/execution-journals/ capturing only stale references, blockers, and verification failures, keeping it scannable for reviewers. - Worktree selection gate: Targets the correct git worktree before editing, with confirmation when another session may be actively editing it. - Use Case: After /plan produces an approved implementation plan, run /execute path/to/plan.md to implement it phase by phase, verify with the appropriate pnpm checks, and hand off a clean journal for /ship. ## Quick Start Ask the agent to execute the saved plan at docs/plans/my-feature.md and record any deviations in an execution journal.
