Dev Process Toolkit

A Claude Code plugin that adds Spec-Driven Development (SDD) and TDD workflows to any project. Includes 9 commands, 2 agents, spec templates, and documentation.

Install as Plugin

/plugin marketplace add nesquikm/dev-process-toolkit
/plugin install dev-process-toolkit@nesquikm-dev-process-toolkit

Then run the setup command in your project:

/dev-process-toolkit:setup

This detects your stack, generates a CLAUDE.md, configures settings, and optionally creates spec files — all adapted to your project.

What You Get

Commands

Command	Purpose
/dev-process-toolkit:setup	Set up SDD/TDD process for your project
/dev-process-toolkit:spec-write	Guide through writing spec files (requirements, technical, testing, plan)
/dev-process-toolkit:implement	End-to-end feature implementation with TDD and self-review
/dev-process-toolkit:tdd	RED → GREEN → VERIFY cycle
/dev-process-toolkit:gate-check	Deterministic quality gates (typecheck + lint + test)
/dev-process-toolkit:spec-review	Audit code against spec requirements
/dev-process-toolkit:visual-check	Browser-based UI verification via MCP
/dev-process-toolkit:pr	Pull request creation
/dev-process-toolkit:simplify	Code quality review and cleanup

Agents

• code-reviewer — Reviews code for quality, patterns, and security
• test-writer — Writes tests following project conventions

Manual Setup

If you prefer not to install the plugin, you can copy files manually from plugins/dev-process-toolkit/:

1. Copy skills/ contents to your project's .claude/skills/ directory
2. Copy agents/ contents to your project's .claude/agents/ directory
3. Look for <!-- ADAPT --> comments in each skill and replace with your project's commands
4. Create your CLAUDE.md using templates/CLAUDE.md.template
5. Run /gate-check to verify everything works

See plugins/dev-process-toolkit/docs/adaptation-guide.md for detailed instructions.

Core Philosophy

Three layers prevent AI agents from going off the rails:

1. Specs — Human-written requirements are the source of truth
2. Deterministic gates — Typecheck + lint + test must pass (no LLM judgment)
3. Bounded self-review — Max 2 rounds, then escalate to human

The key insight: deterministic checks always override LLM judgment. A failing test means "fix it," not "maybe it's fine."
