Find stale attic items and archive them. Use when the user says "prune the attic", "the attic is getting big", "clean up old items", or "archive old findings". This is about the ATTIC's own contents, never about cleaning up source code.
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
# Prune the attic
```bash
node "${CLAUDE_SKILL_DIR}/../attic/scripts/attic.js" prune $ARGUMENTS
```
**Dry run is the default.** The command lists candidates and moves nothing
until `--apply` is passed.
1. Run it without `--apply` first, always. Show the candidate list.
2. Archiving is not deletion: items move to `.attic/archive/`, stay
recallable by `/attic-recall`, and simply stop being injected. Say this,
because "prune" sounds destructive and users hesitate.
3. Ask for confirmation before `--apply`. Never apply in the same turn the
user first mentions pruning, unless they explicitly said to go ahead.
4. Pinned items are skipped automatically. Report how many were skipped.
5. Restore anything with
`node .../attic.js archive <slug> --restore`.
Defaults to items older than 90 days. `--kind output` is the safest filter,
since stale command output ages worst.
Never delete an item file. Never pass `--apply` without the user having seen
the candidate list.Read the whole file at its exact version.
How to install
mdr add nishikantaray/attic/attic-prune@sha256:5d0915af764a7c09The line at the top of this page pins the label v1.6.1, 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.
