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 [P] markers, then implements tasks sequentially or in parallel while marking completed items as [X]. - Checklist Gating: Scans checklists in the feature directory, reports pass/fail status, and asks for confirmation 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 mandatory and optional 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 the entire plan with TDD ordering, progress reporting, and completion validation. ## 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 tasks.md implementation plan with spec-kit?▼

Invoke the speckit-implement skill from the repository root. It runs check-prerequisites.ps1 to locate the feature directory, reads tasks.md and plan.md, then executes tasks phase by phase in dependency order, marking each completed task as [X].

What happens if checklists have unchecked items before implementation?▼

The skill scans all files in the checklists directory, counts checked and unchecked items, and displays a status table. If any items are unchecked, it stops and asks whether to proceed before continuing with implementation.

Does speckit-implement require a specific project structure?▼

Yes, it requires a spec-kit project with a .specify directory containing scripts, plus a feature directory with tasks.md and plan.md. If tasks are missing, it suggests running /speckit-tasks first to generate the task list.

How are parallel and sequential tasks handled during implementation?▼

Tasks marked with [P] can run in parallel, while tasks affecting the same files run sequentially. Execution halts if a non-parallel task fails, but parallel task failures are reported while successful ones continue.

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.
