SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Turning a written implementation plan into working code requires manually tracking dozens of tasks, dependencies, and checklists, which is error-prone and easy to lose track of. This Skill automates the execution phase of a spec-kit project by reading tasks.md and systematically completing every task in the correct order. ## Core Features & Use Cases - Checklist Gate: Scans all checklists in the feature directory, reports pass/fail status in a table, and asks for confirmation before proceeding when items are incomplete. - Phased Task Execution: Parses tasks.md for phases, dependencies, and parallel [P] markers, then executes setup, tests, core, integration, and polish work in the correct order while marking completed tasks as [X]. - Project Setup Verification: Detects the project's tech stack and creates or verifies ignore files (.gitignore, .dockerignore, .eslintignore, and others) with the appropriate patterns. - Extension Hooks: Runs optional and mandatory before/after implementation hooks defined 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 end-to-end with progress reporting and validation against the specification. ## 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 automatically?▼

Run the speckit-implement command in a spec-kit project. It reads tasks.md, executes each phase in dependency order, runs parallel [P] tasks together, and marks each finished task as [X] in the tasks file.

What is required before running speckit-implement?▼

The project must have a spec-kit structure with a .specify directory and a complete tasks.md generated by /speckit-tasks. If tasks are missing or incomplete, the Skill suggests regenerating the task list first.

Does speckit-implement run when checklists are incomplete?▼

It stops and displays a status table showing incomplete checklist items, then asks whether to proceed. Execution only continues after explicit user confirmation, or automatically when all checklists pass.

How does speckit-implement handle task failures?▼

It halts execution when a non-parallel task fails and reports the error with debugging context. For parallel [P] tasks, it continues with successful tasks and reports the failed ones separately.

What are extension hooks in spec-kit implementation?▼

Hooks are commands defined in .specify/extensions.yml under hooks.before_implement or hooks.after_implement. Mandatory hooks execute automatically, while optional hooks are presented for the user to run manually.
