Attic Prune

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.

File contents

Prune the attic

First, in the same shell command as anything below, locate the script:

ATTIC_JS=$(ls -d "${CODEX_HOME:-$HOME/.codex}"/plugins/cache/attic/attic/*/skills/attic/scripts/attic.js "${CODEX_HOME:-$HOME/.codex}"/skills/attic/scripts/attic.js "$HOME"/.agents/skills/attic/scripts/attic.js .agents/skills/attic/scripts/attic.js 2>/dev/null | sort -V | tail -1)

node "$ATTIC_JS" prune $ARGUMENTS

Dry run is the default. The command lists candidates and moves nothing until --apply is passed.

Run it without --apply first, always. Show the candidate list.
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.
Ask for confirmation before --apply. Never apply in the same turn the user first mentions pruning, unless they explicitly said to go ahead.
Pinned items are skipped automatically. Report how many were skipped.
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.
