SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Automates the end-to-end implementation workflows by running and coordinating all tasks defined in tasks.md, ensuring traceable progress and validated completion.

Core Features & Use Cases

  • Phase-driven execution: Setup, Tests, Core, Integration, and Polish with mandatory sequential steps and parallel task support.
  • TDD-first coordination: Tests are executed before corresponding implementation tasks to ensure correctness.
  • Progress tracking and error handling: Monitors completion, handles failures, and provides clear guidance for next steps.
  • Extension hooks support: Checks and executes pre/post hooks via .specify/extensions.yml when present.

Quick Start

Instruct speckit-implement to execute every task from tasks.md in the defined order and verify each phase upon completion.

Frequently Asked Questions about speckit-implement

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I automate end-to-end implementation tasks defined in a tasks.md file?

To automate tasks.md execution, you need a spec-kit style project with a plan.md and tasks.md. The Skill coordinates and validates all tasks sequentially, marking them complete after successful execution.

How does test-driven development execution work during automated workflow implementation?

Test-driven development execution runs tests before corresponding implementation tasks. This TDD-first coordination ensures correctness by validating tests initially and monitoring completion across Setup, Tests, Core, Integration, and Polish phases.

What's the best way to structure a spec-kit project for phase-driven workflow automation?

Phase-driven workflow automation requires structuring work into Setup, Tests, Core, Integration, and Polish phases. You must organize your repository with a tasks.md file and plan.md to enable mandatory sequential steps and parallel task support.

Can I use extension hooks to customize automated task execution?

Yes, you can customize automated task execution using extension hooks. The Skill checks and executes pre/post hooks defined in a .specify/extensions.yml file when present, allowing you to inject custom logic into the workflow.

Why does my automated implementation workflow fail before completing all tasks.md phases?

Automated implementation workflows fail when errors occur during task execution or validation. The Skill handles failures by monitoring completion, providing clear guidance for next steps, and ensuring tasks are only marked complete after successful execution.

Do I need a plan.md file to run automated spec-kit implementation tasks?

Yes, a plan.md file is required to run automated spec-kit implementation tasks. You must have a properly organized repository containing both tasks.md and plan.md to execute the end-to-end implementation workflow successfully.
