skill-metrics is a command for Claude Code from athola/skrills. It costs 15 tokens per session (207 once invoked), scanned A, original, MIT.

A metrics command for summarising discovered coding skills. It reports counts, quality ratings, token usage, dependencies, and common categories, with an optional validation summary.

In plain words
What is it for?
Use it to review skill inventory statistics, compare quality levels, inspect token consumption, find widely used dependencies, and see common tags.
Why use it?
It turns a large skill collection into measurable information, so you can understand its size, quality, cost, and structure without checking entries one by one.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

skill-metrics scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Skill Metrics

Get skill metrics and statistics using the skrills MCP server.

Use the mcp__plugin_skrills_skrills__skill-metrics tool with:

  • include_validation: Include validation summary (slower but more complete)

Parse $ARGUMENTS for:

  • --include-validation or -v: Include validation stats

Report metrics including:

  • Total skill count by source (Claude, Codex, Copilot)
  • Quality score distribution (excellent, good, fair, poor)
  • Token usage statistics (total, average, max)
  • Dependency patterns (most depended-on skills)
  • Common tags and categories

Handle errors:

  • If no skills found: Report empty state with setup suggestions
  • If validation fails: Report partial metrics with warning
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
