Tsumiki is an AI-driven development framework distributed as a Claude Code plugin that streamlines the software development lifecycle from requirements to implementation. It provides structured workflows for context analysis, planning, test-driven development, code investigation, and automated debugging through slash commands. Developers use it to orchestrate AI-assisted tasks like generating implementation plans, running test-first development cycles, analyzing codebases, and reverse-engineering documentation from existing code. The plugin can also be adapted for other AI coding tools like Cursor, Gemini CLI, and Copilot through the rulesync utility.

Key Features

Dev Skills workflow covering project initialization, context analysis, planning, test-first implementation, verification, and debugging
DCS (Design, Code, System) commands for sequence diagrams, state transition analysis, impact analysis, and bug investigation
Reverse engineering commands that generate requirements, design docs, test specs, and task structures from existing codebases
Automated orchestration that analyzes complex requests and delegates to specialized agent teams
Legacy Kairo workflow for comprehensive EARS-notation requirements through iterative task implementation
Test-driven development commands supporting Red-Green-Refactor cycle execution
Utility commands for auto-debugging test failures, fixing build errors, stabilizing flaky tests, and resolving timeouts
Integration with rulesync for cross-platform support in Cursor, Gemini CLI, Copilot, and other AI coding assistants

Use Cases

  • 01Analyzing existing projects to generate context documentation and implementation plans
  • 02Running automated test-first development cycles with continuous task execution
  • 03Investigating codebases through sequence diagrams, impact analysis, and performance profiling
  • 04Reverse-engineering legacy code to produce requirements documents, design specs, and test cases
  • 05Orchestrating complex development workflows across multiple AI agents
  • 06Automatically debugging test failures, build errors, and environment-specific issues

tsumiki — FAQ

What is Tsumiki?+

Tsumiki is an AI-driven development framework packaged as a Claude Code plugin that provides structured commands for requirements analysis, design, implementation, testing, and code investigation. It supports both modern Dev Skills workflows and legacy Kairo/TDD methodologies.

How do I install Tsumiki in Claude Code?+

Run '/plugin marketplace add https://github.com/classmethod/tsumiki.git' followed by '/plugin install tsumiki@tsumiki' in Claude Code. Commands are then available with the /tsumiki: prefix (e.g., /tsumiki:dev-plan).

Can I use Tsumiki with AI coding tools other than Claude Code?+

Yes, Tsumiki can be adapted for Cursor, Gemini CLI, Copilot, Roo, and Codex CLI using the rulesync utility. Run 'npx -y rulesync import --targets claudecode --features commands,subagents' followed by 'npx -y rulesync generate --targets <tool>' in your project root.

What are the legacy commands and how do I access them?+

The legacy Kairo, TDD, and DIRECT commands are separated into an optional tsumiki-legacy plugin. Install it with '/plugin install tsumiki-legacy@tsumiki' and use commands with the /tsumiki-legacy: prefix (e.g., /tsumiki-legacy:kairo-requirements).

Is Tsumiki free to use?+

Yes, Tsumiki is open-source and available on GitHub under the classmethod organization. No API keys or external services are required beyond your Claude Code or compatible AI coding tool.

What's the difference between Dev Skills and Kairo workflows?+

Dev Skills is the modern integrated workflow with commands like dev-plan and dev-run for streamlined development. Kairo is the legacy comprehensive flow using EARS-notation requirements and explicit TDD/DIRECT task execution steps, now available in the optional tsumiki-legacy plugin.

How do I install tsumiki?+

Open the source repository on GitHub and follow its README. tsumiki is a plugin — MCP Agents Market links you directly to the official repo.

Is tsumiki free?+

tsumiki is an open-source project hosted on GitHub. Check the repository for its license and any usage requirements.
