What problem does it solve? Turning a written 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-kit project by reading tasks.md and plan.md, then implementing every task in the correct order. ## Core Features & Use Cases - Checklist gating: Scans all checklists in the feature directory, reports pass/fail status in a table, and asks for confirmation before proceeding when items are incomplete. - Phased task execution: Parses tasks.md for phases, dependencies, and parallel [P] markers, then runs setup, tests, core, integration, and polish work in order while marking completed tasks as [X]. - Project setup verification: Detects the repo's tech stack and creates or verifies ignore files (.gitignore, .dockerignore, .eslintignore, and others) with the correct patterns. - Use Case: After generating a task list with /speckit.tasks, run this Skill to implement the entire feature, with tests written before code and progress reported after each task. ## Quick Start Ask the agent to run the speckit-implement skill to execute all tasks in tasks.md and build the planned feature.
