**We do not ship the content of your judgment. We ship the forms.**

**Make the AI write the approval slip.** Before any outward action (send, publish, update a canonical document), the agent writes the recipient, the content, the grounds, whether it can be undone, and where it is unsure; the human reads only the 'unsure' field and signs or stops. A button approval becomes a ritual; a slip cannot be signed unread.

kagemusha is **a set of Markdown forms plus the scripts that run them**, for the AI coding agent you already use (Claude Code, Codex, Cursor, …): it makes **inward work run on its own and anything outward wait for your approval**, and it returns the reasons you rejected something to the next run as standing rules. It is not a resident agent and not a SaaS, and **your own judgment criteria are not included**.

**Fits** you if operations that cannot be undone are part of your day and you are willing to write down why you rejected something. **Does not fit** you if you want ready-made judgment criteria, or an approval SaaS for a team.

**Works with Claude Code and Codex CLI** — one instructions file, one set of forms, one command line built for whichever you run ([what maps to what](#works-with-claude-code-and-codex-cli)).
