skill-graveyard

CLI that audits Claude Code skill usage. Two signals from one parser:

1. Dead installs — installed but never invoked → safe to remove.
2. Hallucinated invocations — invoked but not installed → typos, external-framework registrations, or model tool/skill confusion.

How to invoke

Run via npx skill-graveyard@latest <subcommand> [flags] — no install needed.

Subcommands

• audit (default) — classify into active / dead / missing / hallucinated. Flags: --days N, --only <bucket>, --json, --claude-dir <path>.
• prune — print removal commands for dead skills. --apply to execute (user/agents only; plugin removals always print only).
• suggest — triage hallucinated/missing into actionable buckets.
• projects — per-project usage breakdown (cwd from sessions).
• cost — token cost estimate of installed metadata vs invocations.
• outdated — check installed plugins / git skills for upstream updates (network).
