What problem does it solve? Turning a written implementation plan into working code requires manually tracking dozens of tasks, dependencies, and validation steps, which is error-prone and easy to lose track of mid-project. ## Core Features & Use Cases - Task Plan Execution: Parses tasks.md to extract phases, dependencies, and parallel markers, then executes tasks in the correct order with TDD discipline. - Checklist Gating: Scans checklist files before implementation and halts for user confirmation if any items are incomplete. - Project Setup Verification: Detects the project stack and creates or verifies ignore files (.gitignore, .dockerignore, .eslintignore, and others) with appropriate patterns. - Extension Hooks: Supports optional and mandatory pre/post-implementation hooks defined in .specify/extensions.yml. - Use Case: After generating a task breakdown with spec-kit, run this Skill to implement the entire feature phase-by-phase, marking completed tasks as [X] in tasks.md and validating results against the specification. ## Quick Start Run the speckit-implement skill to execute all tasks in tasks.md for the current feature.
