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 with progress tracking. ## Core Features & Use Cases - Task Plan Execution: Parses tasks.md for phases, dependencies, and parallel markers, then executes setup, tests, core, integration, and polish phases in order with TDD discipline. - Checklist Gating: Scans FEATURE_DIR/checklists/ before implementation, reports completion status, and halts for user confirmation when checklists are incomplete. - Project Setup Verification: Detects the tech stack from plan.md and creates or verifies ignore files (.gitignore, .dockerignore, .eslintignore, and others) with technology-appropriate patterns. - Extension Hooks: Runs optional and mandatory before_implement and after_implement 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 each completed task as [X], and receive a completion report validated against the specification. ## Quick Start Run the speckit-implement skill to execute all tasks in tasks.md for the current feature and report completion status.

FAQPage Schema
How do I execute a tasks.md implementation plan with spec-kit?▼

Invoke the speckit-implement skill after generating tasks.md with /speckit-tasks. It runs check-prerequisites.sh, loads plan.md and tasks.md, then executes each phase in dependency order, marking completed tasks as [X].

What happens if checklists are incomplete before implementation?▼

The skill scans all files in FEATURE_DIR/checklists/, counts completed and incomplete items, and displays a status table. If any checklist has incomplete items, it stops and asks whether to proceed before continuing.

Does speckit-implement require a specific project structure?▼

Yes, it requires a spec-kit project with a .specify/ directory containing scripts like check-prerequisites.sh, plus a feature directory with tasks.md and plan.md. Optional files like data-model.md, contracts/, and research.md are read when present.

How does the skill handle parallel and sequential tasks?▼

Tasks marked with [P] in tasks.md can run in parallel, while sequential tasks run in listed 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 under hooks.before_implement or hooks.after_implement in .specify/extensions.yml. Mandatory hooks execute automatically and the skill waits for their result; optional hooks are displayed for manual invocation.
