Ethan has ~400 custom tools but no idea which ones are actually firing versus quietly dead. This scans every tool in ~/.claude/tools/ (or wherever they live), cross-references last-execution timestamps from systemd journal + cron logs + shell history, and emails a weekly 'autopsy' listing tools that haven't run in 60+ days alongside their nearest living cousin — so pruning becomes a one-line decision instead of an archaeology dig.
Create ~/.local/bin/tool-autopsy: (1) enumerate tools via `ls ~/.claude/tools/` and `systemctl list-units 'service:*'`; (2) for each, grep last invocation from `journalctl --since '90 days ago' -g
