NishikantaRay Pin an attic item
node "${CLAUDE_SKILL_DIR}/../attic/scripts/attic.js" pin $ARGUMENTS
Pinned items occupy a reserved share of the injected index, so they survive even when hundreds of newer items exist. That budget is finite: pin the handful of things that must always be in context, not everything important.
Good candidates: an architectural decision the whole project depends on, a constraint that is easy to forget, the location of something non-obvious.
Bad candidates: a finding about code that changes weekly, anything already obvious from the repository.
Reply in one line with what was pinned and the current pinned count from
/attic-index. If the user is pinning a fifth or later item, say plainly
that the pinned tier is small and ask which one should be unpinned.
