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 hard to audit. This Skill automates that execution phase of a spec-driven development workflow. ## Core Features & Use Cases - Task Plan Execution: Parses tasks.md to extract phases, dependencies, and parallel markers, then executes tasks in the correct order following a TDD approach. - Checklist Gating: Scans checklist files before implementation and stops to ask for confirmation when unchecked items remain. - Project Setup Verification: Detects the project's tech stack and creates or verifies ignore files such as .gitignore, .dockerignore, and .eslintignore. - Extension Hooks: Runs mandatory and optional pre- and post-implementation hooks declared in .specify/extensions.yml. - Use Case: After generating a specification, plan, and task breakdown with spec-kit, run this Skill to implement the entire feature, marking each completed task as [X] in tasks.md and reporting progress per phase. ## Quick Start Ask the agent to run the speckit-implement skill to execute all tasks in tasks.md for the current feature.
