What problem does it solve? Turning a written specification and task breakdown into working code is error-prone when done ad hoc: tasks get skipped, dependencies are ignored, and checklists go unverified. This Skill automates the execution phase of a spec-kit project by reading tasks.md and plan.md, then implementing every task in the correct order with progress tracking. ## Core Features & Use Cases - Phased task execution: Parses tasks.md for phases (Setup, Tests, Core, Integration, Polish), respects sequential vs parallel [P] dependencies, and marks completed tasks as [X]. - Checklist gating: Scans FEATURE_DIR/checklists/ before starting, reports pass/fail status per checklist, and asks for confirmation when items are incomplete. - Project setup verification: Detects the repo's tech stack and creates or verifies ignore files (.gitignore, .dockerignore, .eslintignore, etc.) with technology-appropriate patterns. - Extension hooks: Runs mandatory and optional before_implement/after_implement hooks declared in .specify/extensions.yml. - Use Case: After running /speckit-tasks to generate a task list for a new feature, invoke this Skill to implement the entire feature end-to-end, with TDD ordering and a final completion report. ## Quick Start Run the speckit-implement skill to execute all tasks in tasks.md for the current feature, optionally passing guidance or a task filter as an argument.
