SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Turning a written specification and task breakdown into working code requires disciplined, phase-by-phase execution; this Skill automates that by reading tasks.md and plan.md from a spec-kit project and executing every task in dependency order. ## Core Features & Use Cases - Task Plan Execution: Parses tasks.md for phases, dependencies, and parallel markers, then implements tasks in order following a TDD approach. - Checklist Gating: Scans checklists in the feature directory, reports pass/fail status, and asks before proceeding when items are unchecked. - Project Setup Verification: Detects the tech stack and creates or verifies ignore files (.gitignore, .dockerignore, .eslintignore, and others) with appropriate patterns. - Extension Hooks: Runs optional and mandatory before/after implementation hooks declared in .specify/extensions.yml. - Use Case: After running /speckit-tasks to generate a task list for a new feature, invoke this Skill to implement all tasks, mark them complete in tasks.md, and receive a completion report. ## Quick Start Run the speckit-implement skill to execute all tasks in tasks.md for the current feature.

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

Invoke the speckit-implement skill in a project with a .specify directory. It runs check-prerequisites.sh, reads tasks.md and plan.md, then executes each task phase in dependency order, marking completed tasks as [X].

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 require tasks.md to exist?▼

Yes, it requires a complete task breakdown in tasks.md generated by /speckit-tasks. If tasks are missing or incomplete, it suggests running /speckit-tasks first to regenerate the task list.

How does the skill handle parallel and sequential tasks?▼

Tasks marked [P] can run in parallel, while sequential tasks run in dependency order. Tasks affecting the same files run sequentially, and execution halts if any non-parallel task fails.

What are extension hooks in spec-kit implementation?▼

Hooks are commands declared in .specify/extensions.yml under hooks.before_implement or hooks.after_implement. Mandatory hooks execute automatically and the skill waits for their result; optional hooks are displayed for manual invocation.
