What problem does it solve? Turning a written task breakdown into working code is error-prone when done ad hoc: tasks get skipped, dependencies are ignored, and progress is lost. This Skill drives the implementation phase of a spec-kit project by reading tasks.md and executing every task in the correct order with progress tracking. ## Core Features & Use Cases - Phased task execution: Parses tasks.md into phases (Setup, Tests, Core, Integration, Polish), respects sequential dependencies, and runs [P]-marked tasks in parallel. - Checklist and hook gating: Verifies completion checklists before starting and dispatches before/after extension hooks from .specify/extensions.yml, halting on failed mandatory hooks. - Project setup verification: Detects the tech stack from plan.md and creates or updates ignore files (.gitignore, .dockerignore, .eslintignore, and others) with the right patterns. - Use Case: After running /speckit-tasks for a new feature, invoke this Skill to implement the entire plan — it writes tests first, builds core modules, marks each completed task [X] in tasks.md, and reports a completion summary. ## Quick Start Run the speckit-implement skill to execute all tasks in tasks.md for the current feature.
