Can I use this with an existing codebase?

Yes, it includes a 'Map Codebase' command that analyzes your current stack, architecture, and conventions to ensure the AI understands your project structure before starting work.

Does it support git workflows?

Yes, the skill enforces atomic git commits linked to specific tasks and verification steps, ensuring a clean and traceable version control history.

What is 'auto-sizing' in this skill?

Auto-sizing dynamically adjusts the planning depth—skipping design or task phases for small fixes while requiring full documentation and architectural analysis for complex features.

How does it handle long development sessions?

It uses a persistent STATE.md file to track decisions, blockers, and progress, allowing you to pause and resume work seamlessly without losing context.

生産性とワークフロー

Implements an adaptive 4-phase workflow—Specify, Design, Task, and Execute—to ensure high-precision project planning and implementation.

The Spec-Driven Development skill provides a disciplined framework for managing the software development lifecycle within AI coding environments. By utilizing an adaptive 'auto-sizing' principle, it intelligently adjusts its depth based on task complexity, ranging from an express 'Quick mode' for bug fixes to a full-scale architectural design for complex features. The skill maintains project integrity through a structured .specs/ directory, ensuring requirement traceability, persistent session memory, and atomic git commits, making it the ideal tool for both starting greenfield projects and mapping existing brownfield codebases.
