SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Speckit-implement automates the end-to-end execution of a spec-kit project by processing and enacting the tasks.md plan.

Core Features & Use Cases

  • Parses tasks.md to derive a phased execution plan and dependency graph.
  • Enforces a test-first development approach and phase-by-phase validation.
  • Orchestrates setup, tests, core development, integration, and polish with progress reporting and error handling.

Quick Start

Run speckit-implement to execute the predefined tasks.md plan for your spec-kit project.

FAQPage Schema
How do I automate end-to-end project implementation from a plan?

Automate end-to-end project implementation by parsing a tasks.md file to derive a phased execution plan. The tool orchestrates setup, tests, core development, integration, and polish stages automatically.

What is test-driven development automation for task management?

Test-driven development automation enforces a test-first approach across phased execution. It processes your tasks.md plan, applies validation checkpoints, and reports progress during artifact generation and core development.

How do I execute a phased rollout with dependency resolution?

Execute a phased rollout by interpreting tasks.md to build a dependency graph, then progressing sequentially through setup, tests, core, integration, and polish stages with validation checkpoints ensuring safe progression.

Can I use hook-based extension points for custom project workflows?

Hook-based extension points allow custom project workflow integration during automated implementation. The execution engine supports these hooks alongside error reporting and validation checkpoints while processing your tasks.md plan.

Why does my tasks.md automated implementation stop at validation checkpoints?

Automated implementation stops at validation checkpoints to ensure safe progression through phases. The tool enforces test-first development and phase-by-phase validation, halting execution and providing error reporting when checks fail.

Do I need a tasks.md file to start automated project implementation?

A tasks.md file is required to start automated project implementation. The tool parses this file to derive the phased execution plan and dependency graph needed to orchestrate setup, tests, core, integration, and polish stages.
