What problem does it solve? After implementing a plan, it is hard to know whether every phase was actually completed, whether automated checks pass, and whether the code deviates from what was specified. This Skill systematically verifies implementation work against the original plan before it ships. ## Core Features & Use Cases - Context Discovery: Locates the implementation plan and gathers evidence from recent git commits and diffs to understand what was changed. - Systematic Validation: Checks each plan phase for completion, runs automated verification commands like build, test, and precommit, and assesses manual testing criteria. - Validation Report Generation: Produces a structured report covering implementation status, verification results, deviations from the plan, potential issues, and manual testing steps. - Use Case: After finishing a multi-phase feature implementation and committing the changes, run this Skill to confirm all success criteria pass, catch missing test coverage, and document deviations before creating a pull request. ## Quick Start Ask the AI to validate that the implementation plan was correctly executed by checking recent commits and running the automated verification commands.
