What problem does it solve? Turning a written specification and task breakdown into working code is error-prone: tasks get skipped, dependencies are ignored, and checklists go unverified. This Skill automates the execution phase of a spec-driven workflow by reading tasks.md and plan.md, then implementing every task in the correct order with progress tracking. ## Core Features & Use Cases - Checklist gating: Scans all checklist files in the feature directory, reports completion status in a table, and asks for confirmation before proceeding when items are incomplete. - Phase-based execution: Parses task phases (Setup, Tests, Core, Integration, Polish), respects sequential vs parallel [P] dependencies, and follows a tests-before-code TDD approach. - Project setup verification: Detects the tech stack and creates or verifies ignore files (.gitignore, .dockerignore, .eslintignore, etc.) with technology-appropriate patterns. - Use Case: After running /speckit.tasks to generate a task breakdown for a new feature, invoke this Skill to implement all tasks end-to-end, marking each completed task as [X] in tasks.md and validating the result against the original specification. ## Quick Start Run the speckit.implement skill to execute all tasks in tasks.md for the current feature and mark each completed task as done.
