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

  1. Create a prompt

    Give it a key, a description, and initial content — this becomes version 1.

  2. Edit and save a new version

    Editing and saving creates a new version. Every earlier version stays exactly as it was.

  3. 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.
