SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Turning a written implementation plan into working code requires manually tracking dozens of tasks, dependencies, and validation steps. This Skill automates that execution by reading a spec-kit project's tasks.md and systematically completing every task in the correct order. ## Core Features & Use Cases - Phased Task Execution: Parses tasks.md into phases (Setup, Tests, Core, Integration, Polish) and executes them sequentially while respecting parallel [P] markers and file-level dependencies. - Checklist Gating: Scans checklists in the feature directory, reports pass/fail status in a table, and asks for confirmation before proceeding when items are unchecked. - Project Setup Verification: Detects the technology stack from plan.md and creates or verifies ignore files (.gitignore, .dockerignore, .eslintignore, etc.) with appropriate patterns. - Extension Hooks: Runs optional and mandatory pre/post-implementation hooks declared in .specify/extensions.yml. - Use Case: After running /speckit-tasks to generate a task breakdown for a new feature, invoke this Skill to implement the entire feature—writing tests first, then code—while marking each completed task as [X] in tasks.md. ## Quick Start Ask the assistant to run the speckit-implement skill to execute all tasks in the current feature's tasks.md file.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I execute a spec-kit implementation plan automatically?▼

Run the speckit-implement skill in a project with a .specify directory. It reads tasks.md, executes tasks phase by phase respecting dependencies and parallel markers, and marks each completed task as [X] in the tasks file.

What files does speckit-implement need before running?▼

It requires tasks.md and plan.md in the feature directory, discovered via check-prerequisites.sh. It optionally reads data-model.md, contracts/, research.md, quickstart.md, and .specify/memory/constitution.md for additional context.

What happens if checklists have unchecked items before implementation?▼

The skill scans all checklist files, displays a status table with checked and unchecked counts, then stops and asks whether to proceed. Implementation only continues after explicit user confirmation.

Does speckit-implement follow test-driven development?▼

Yes. The execution rules require test tasks to run before their corresponding implementation tasks, following a phase order of setup, tests, core development, integration, and polish.

What are extension hooks in speckit-implement?▼

Hooks are commands declared in .specify/extensions.yml under hooks.before_implement or hooks.after_implement. Mandatory hooks are executed automatically and the skill waits for their result; optional hooks are only suggested to the user.

What should I do if tasks.md is missing or incomplete?▼

The skill assumes a complete task breakdown exists. If tasks are missing or incomplete, run /speckit-tasks first to generate the task list before attempting implementation.
