SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Speckit Implement automates turning a task breakdown into a working feature by following a structured, test-driven workflow that reduces manual orchestration and drift.

Core Features & Use Cases

  • End-to-end task execution: transforms a planned task list into concrete implementation steps, including setup, tests, core development, integration, and polish.
  • TDD-aligned workflow: emphasizes writing tests before coding and validating progress at checkpoints.
  • Progress tracking & task completion: marks completed tasks in the tasks.md file and reports status.

Quick Start

Initialize and run the speckit-implement workflow on your repository to begin implementing the planned tasks.

FAQPage Schema
How do I automate feature implementation from a task breakdown using TDD?

Automate feature implementation by sequencing tasks through phases like Setup, Tests, Core, Integration, and Polish. This enforces a test-driven development workflow with dependency-aware execution and validation checkpoints.

What is the best way to track feature development progress in a tasks.md file?

Track development progress by automatically marking completed tasks in the tasks.md file. The workflow reports status updates and handles task completion marking as it executes each phase.

How do I set up a TDD project workflow with dependency-aware task sequencing?

Set up a TDD workflow by organizing tasks into structured phases with dependency-aware sequencing. The system executes setup, tests, and core development while validating progress at each checkpoint.

Can I run parallel task execution during test-driven development?

Yes, dependency-aware sequencing supports optional parallelism during task execution. This allows concurrent task processing while maintaining validation checkpoints across the test-driven workflow.

Does automated task execution work with projects organized by implementation phases?

Automated task execution works specifically with projects organized by phases such as Setup, Tests, Core, Integration, and Polish. It transforms the planned task list into concrete implementation steps.

Why does my structured feature implementation drift from the original task plan?

Feature implementation drifts when manual orchestration lacks structured checkpoints. Automating the end-to-end workflow with test-driven validation and progress reporting reduces drift and ensures tasks.md alignment.
