Track every prompt edit without ever losing history.
“プロンプトのGit”
Every edit to a prompt or worker definition is saved as a new version. Rolling back just moves a pointer — nothing is ever deleted.

What it does
- 01Append-only history
- Every save creates version 1, 2, 3… Existing versions are never overwritten.
- 02Rollback is just a pointer move
- Rolling back only changes which version is “current” — past versions stay intact and browsable.
- 03Line-level diff
- Pick any two versions and see exactly which lines were added or removed.
- 04Quality trend per version
- If an external system POSTs a quality score tied to a version ID, you see which change helped or hurt.
- 05Usable from any AI system
- comet-taskAI, ai-scheduler, your own scripts — anything that can read/write over HTTP can integrate.
- 06API key authentication
- External access is protected by API keys, stored hashed and shown only once at issuance.
How it works
Create a prompt
Give it a key, a description, and initial content — this becomes version 1.
Edit and save a new version
Editing and saving creates a new version. Every earlier version stays exactly as it was.
Compare and roll back
Check the diff, and roll back to an earlier version if quality dropped.
Good to know
- Nothing is ever deleted — neither rollback nor a new save removes a past version.
- Rollback is pointer-only — it never creates or deletes a version.
- Diffs are an LCS-based line diff — additions and removals shown accurately.
