Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# AI Prune

If a slash or dollar invocation already added these instructions to the conversation, follow them directly. In that
case, do not invoke this skill again through a skill tool.

Review everything under `.ai/` and `.cache/`. Decide which entries are clearly outdated relative to the repository's
current state. Archive the matching `.ai/` entries. Move the matching `.cache/` entries to the macOS Trash. Prefer to
keep entries. Change only entries with concrete evidence that they are outdated.

This skill runs only on macOS. If `uname -s` is not `Darwin` or `/usr/bin/trash` is missing, stop and report.

## Arguments

- `path` (optional): Repository root or any path inside the repository. Default to the current directory.
- `--dry-run` (optional): Report the planned moves and deletions without changing the filesystem.

## Never Touch

- `.ai/todos/` and `.ai/archive/` (including everything beneath them).
- `TODO.md` and `PROMPT.md` files anywhere: they are user-owned notes. Do not read or move them.
- Live agent state: coordination ledgers, leases, locks, inboxes, and notification queues (for example `.ai/coord/`,

How to install

The exact contents, by fingerprint
mdr add paulrberg/agent-skills/ai-prune@sha256:9ae799aecf1d9e4e

The line at the top of this page pins the label git:20261005.b512acb, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
