What problem does it solve? Written implementation plans often drift during execution: steps get skipped, verifications are ignored, and blockers are worked around instead of surfaced. This Skill enforces disciplined execution of a written plan in a separate session, with critical review up front and explicit stop conditions when things go wrong. ## Core Features & Use Cases - Critical Plan Review: Loads the plan, identifies questions or concerns, and raises them with the human partner before any code is written. - Task-by-Task Execution: Converts plan items into todos, marks each in progress, follows steps exactly, and runs the specified verifications before marking complete. - Controlled Completion and Stop Conditions: Hands off to the finishing-a-development-branch sub-skill after all tasks pass, and halts immediately on blockers, unclear instructions, or repeated verification failures instead of guessing. - Use Case: After a planning session produces an implementation plan document, start a fresh session with this Skill to execute every task in an isolated git worktree, verify each step, and finish the development branch cleanly. ## Quick Start Use the executing-plans skill to implement the plan in docs/plans/feature-auth.md and stop if anything is unclear.
