These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

code-review-claude-skills 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 7d 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.

Claude Skills and Agent Code Review Patterns

Stack-specific rules loaded by dh:code-reviewer when SKILL.md, agent frontmatter files, or plugin.json files are detected.

Frontmatter Validity

  • name must match the containing directory name exactly — mismatch causes lookup failures
  • name must satisfy ^[a-z][a-z0-9-]*$ — lowercase letters, digits, hyphens only
  • description must be a single-line string — no YAML multiline indicators (>-, |-, >, |)
  • tools field (in agents) must be a comma-separated string, not a YAML array — Read, Grep, Glob not [Read, Grep, Glob]
  • model must be one of sonnet, opus, haiku, or inherit — no version strings, no full model IDs
  • Run uvx skilllint@latest check --fix <path> after every frontmatter edit — auto-fixes YAML formatting issues including quoting

Description Quality

  • The description must contain specific trigger keywords
  • First 1024 characters are most important — front-load trigger conditions and activation signals
  • Preferred trigger openers: "Use when", "Activates on", "Triggers on", "Loaded automatically when"
  • Descriptions must be third-person ("Generates commit messages" not "I can help you generate")
  • Vague descriptions produce missed triggers — "Helps with Python stuff" is a blocking finding

Token Budget

  • Skills must not include information Claude already has from training (general language patterns, well-known APIs, common idioms)
  • Include only project-specific context, conventions, and domain knowledge that Claude cannot infer
  • Skills over 4000 tokens should be flagged as oversized (warn); over 6400 tokens are blocking
  • Inline examples are valuable — prefer 2-3 focused examples over exhaustive lists

Scope of Tools

  • allowed-tools in agent frontmatter must be scoped to the minimum required for the agent's task
  • Agents that only review code must not have Write or Edit in their tools list
  • Verification-only agents must not have destructive tools

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.
