takt

TAKT (TAKT Agent Koordination Topology) is an open-source CLI that controls AI coding agents from the outside instead of trusting them to follow prompt rules. Planning, implementation, review, fix loops, human checkpoints, permissions and output contracts are defined in YAML workflow files, so the process is owned by the workflow rather than left to the agent.

Each step gets its own persona, policy, knowledge, instruction and output contract, which keeps context focused instead of letting one long session accumulate. Reviews cannot be silently skipped: findings route work back to fix steps, and human judgment can be requested. You describe a task in conversation, save it to a queue, run takt run to execute queued tasks in isolated worktrees, then use takt list to review diffs, merge, retry or requeue. On GitHub, takt caccia waits for CodeRabbit reviews and handles unresolved bot threads.

Providers include Claude Code, the Claude, Codex, OpenCode and Pi SDKs, the DeepSeek Harness SDK, Cursor, GitHub Copilot CLI and Kiro, so implementation and review can use different agents. Install with npm install -g takt and takt install for the SDK you want. README in English, Japanese and Chinese, with a written and video tutorial. MIT licensed, and built with TAKT itself.
