sdd-mcp

Spec-driven development workflow with approval gates and TDD

Guides features through requirements, design, task planning, and test-first implementation with explicit human approval at every phase. Eliminates vague specs, skipped tests, and untracked progress by storing durable workflow state that survives restarts. Works natively in Claude Code, Codex, and Oh My Pi with built-in security audits, code review, and commit guidance.

Frequently Asked Questions

FAQPage Schema

How to install sdd-mcp?▼

Run `npx skills add yi-john-huang/sdd-mcp --all -g -y` in your terminal to install all skills in this suite globally.

What is spec-driven development?▼

It is a workflow where every feature moves through written requirements, design, and task phases, each requiring your explicit approval before coding begins. This prevents vague specs and untested implementations.

Does sdd-mcp work with Claude Code and Codex?▼

Yes. It installs natively into Claude Code, Codex, and Oh My Pi, placing skills, rules, and agents in each host's expected directories.

How does sdd-mcp handle test-driven development?▼

The implementation and test-generation skills enforce a RED-GREEN-REFACTOR cycle, requiring a failing test before any production code is written. Progress and test evidence are recorded durably so work resumes safely after interruptions.

Can I use sdd-mcp for quick bug fixes?▼

Yes. The simple-task skill handles small fixes and enhancements test-first without starting the full formal workflow.
