What problem does it solve? Turning a written implementation plan into working code requires manually tracking dozens of tasks, dependencies, and validation steps. This Skill automates that execution by reading tasks.md and plan.md from a spec-kit project and carrying out each phase in the correct order. ## Core Features & Use Cases - Checklist gating: Scans all checklists in the feature directory, reports completion status, and asks for confirmation before proceeding when items are incomplete. - Phased task execution: Parses tasks.md for phases, dependencies, and parallel [P] markers, then executes setup, tests, core, integration, and polish work in order while marking completed tasks as [X]. - Project setup verification: Detects the technology stack from plan.md and creates or verifies ignore files such as .gitignore, .dockerignore, and .eslintignore. - Extension hooks: Runs mandatory and optional before_implement and after_implement hooks declared in .specify/extensions.yml. - Use Case: After generating a specification and task breakdown for a new feature, invoke this Skill to implement every task, run the tests first per TDD, and receive a completion report. ## Quick Start Ask the agent to run the speckit-implement skill to execute all tasks in the current feature's tasks.md.
