SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Speckit-implement coordinates and executes a structured task plan defined in tasks.md, enabling consistent, test-driven implementation work within a spec-kit project.

Core Features & Use Cases

  • Setup & prerequisites: verify environment, hooks, and checklist readiness before execution.
  • Task-driven execution: orchestrates setup, tests, core development, integration, and polish in the correct order, respecting dependencies and parallel tasks.
  • Progress tracking & validation: reports status after each phase, halts on critical failures, and ensures completion aligns with the plan.

Quick Start

Run speckit-implement to execute the tasks.md plan end-to-end.

FAQPage Schema
How do I automate task plan execution and enforce TDD in a spec-kit project?

Automate task plan execution by orchestrating setup, tests, and development phases sequentially or in parallel. It enforces TDD, coordinates dependencies from tasks.md, validates completion against the plan, and reports progress after each phase.

What is the best way to coordinate multi-phase development tasks with dependencies?

Coordinate multi-phase development by resolving task dependencies and execution order defined in a tasks.md plan. It orchestrates setup, tests, core development, integration, and polish phases while respecting both sequential and parallel task constraints.

Can I run parallel tasks while maintaining test-driven development in my workflow?

Run parallel tasks while maintaining TDD by orchestrating both sequential and parallel execution from the task plan. It coordinates tests alongside core development, respects dependency order, and validates that completion aligns with the plan.

Do I need a tasks.md file to orchestrate my project setup and validation?

A tasks.md file is required to define phases, dependencies, and execution order for orchestration. It uses this plan to verify environment prerequisites, coordinate setup and tests, enforce TDD, and validate completion against the defined tasks.

Why does my task plan execution halt on critical failures during development?

Task plan execution halts on critical failures to enforce validation and ensure completion aligns with the defined plan. It reports status after each phase, stopping execution when critical issues arise so problems are addressed before proceeding.
