lint-skill

lint-skill is a skill for Claude Code, Codex from lorem-dev/skillkeeper-test-repo. It costs 16 tokens per session (311 once invoked), scanned A, original, MIT.

A grouped example skill whose identifier is tooling/lint-skill rather than just lint-skill. It demonstrates how add-ons can be organized under a tooling group and discovered with related configuration files.

In plain words
What is it for?
Testing grouped skill discovery, group-aware identifiers, source guidance, MCP presets, and the allowed one-level directory layout.
Why use it?
It clarifies the catalogue rules for grouped add-ons, including how names, identity files, guidance, and group presets are resolved.

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

lint-skill 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 2mo 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

lint-skill

What this fixture covers:

  • Scheme 2 (grouped layout). The directory sits two levels deep, so the first path segment becomes the group: this skill's id is tooling/lint-skill, not the bare lint-skill.
  • The group directory itself is not a skill. tooling/ has no SKILL.md, and even if it had one, a directory holding skill subdirectories is not treated as a skill.
  • Group membership reaching the .skid.yml identity file, which records group: tooling alongside the name and source remote. Skills with no group omit the field entirely.
  • Making tooling/mcp.yml discoverable. Group MCP presets are only found when the group holds at least one resolvable skill; this skill and format-skill are what qualify tooling.
  • GUIDE.md inside a grouped skill, which exercises the guidance block key - built from the source remote plus the full group/name id rather than the bare name.

Note that group depth is exactly one. tooling/lint-skill resolves; tooling/nested/lint-skill would not - see deep-nesting/ for that case.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
