What this skill carries — grep references/ for any subject the names below miss: !d=${CLAUDE_SKILL_DIR}; command -v skill-toc >/dev/null 2>&1 && exec skill-toc "$d"; s=$HOME/.claude/skills/plugin-utils/bin/skill-toc; [ -x "$s" ] && exec "$s" "$d"; echo "(skill-toc unavailable: references and scripts are NOT listed here — install the plugin-utils plugin, or start a new session so its bin/ reaches PATH)"

Owns the bibliography as an index: every entry pointing at the right PDF, and that PDF being the version of record.

pincite CONSUMES this index — it resolves footnote → source through file = {...} and through nothing else. So the two failures this skill exists to prevent are both silent in pincite: an entry with no file is a pincite that is never attempted, and an entry pointing at a preprint is a pincite that is confidently wrong.
