SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Turning a written implementation plan into working code requires manually tracking dozens of ordered tasks, dependencies, and validation gates, which is error-prone and easy to lose track of. This Skill automates that execution loop for Spec Kit projects. ## Core Features & Use Cases - Task Plan Execution: Parses tasks.md to extract phases, dependencies, and parallel markers, then executes tasks in the correct order with TDD discipline. - 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 from plan.md and creates or verifies ignore files (.gitignore, .dockerignore, .eslintignore, and others) 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 every task phase-by-phase, marking each completed task as [X] and validating the result 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 automatically?

Run the speckit-implement skill from the repository root of a Spec Kit project. It parses tasks.md, executes tasks phase by phase respecting dependencies and parallel markers, and marks each completed task as [X] in the file.

What is required before running speckit-implement?

The project needs a .specify directory structure with a feature folder containing tasks.md and plan.md. If tasks are missing or incomplete, run /speckit-tasks first to generate the task breakdown.

Does speckit-implement work with unchecked checklists?

It scans all checklist files in the feature's checklists directory and reports pass/fail status. If any items are unchecked, it stops and asks whether to proceed before continuing with implementation.

How does speckit-implement handle parallel and sequential tasks?

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

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 execute automatically and block progress until finished; optional hooks are suggested for manual invocation.
