SkillCheck-Free

作者 olgasafonova · olgasafonova/SkillCheck-Free

Validates Claude Code skills against the open agentskills spec — structure, body, naming, semantics, quality patterns — Critical / Warning / Suggestion.

olgasafonova/SkillCheck-Free is a spec-compliance linter for Agent Skills. Free tier covers: 1.x Structure (YAML frontmatter, name validity, description quality, XML injection), 2.x Body (length, hardcoded dates, empty sections, unqualified MCP refs), 3.x Naming (generic names, verb-noun), 4.x Semantic (conflicting instructions, vague terms, unspecified outputs), 8.x Quality patterns (examples, error handling, triggers), 19.x Design pattern classification, 22.x Knowledge density. Severity tiers: Critical / Warning / Suggestion / Strength.

使用场景

实战用法： SkillCheck-Free

Validate your skill before publishing it to a catalog

👤 Skill authors ⏱ ~20 min beginner

何时使用： Before opening a PR to awesome-claude-skills or anthropics/skills.

步骤
  1. Run SkillCheck on your SKILL.md
    Use SkillCheck-Free — validate ~/my-skill/SKILL.md against the agentskills spec.✓ 已复制
    → Per-rule findings with severities
  2. Fix Critical issues
    Walk me through each Critical finding and propose a fix.✓ 已复制
    → Concrete edits, not 'improve clarity'
  3. Re-run until clean
    Re-validate. Anything still Critical or Warning?✓ 已复制
    → Progress toward zero Critical

结果： A skill that won't be rejected for trivial spec violations.

注意事项
  • Chasing every Suggestion — Suggestions are aspirational; Critical + Warning is the bar for most catalogs
搭配使用： skills-skill-8 · awesome-claude-skill-2

Audit every skill you've installed for quality concerns

👤 Skill hoarders who want to prune ⏱ ~30 min intermediate

何时使用： You installed 20 skills and aren't sure which ones are well-made.

步骤
  1. Decide what to keep
    Which skills have persistent Critical issues I should uninstall?✓ 已复制
    → Prioritized uninstall candidates

结果： A leaner, higher-quality skill collection.

组合

与其他 MCP 搭配，撬动十倍杠杆

skillcheck-free-skill + skills-skill-8

Cross-check: SkillCheck validates spec, huangwb8/auto-test-skill tests robustness

Run SkillCheck first for spec issues, then auto-test-skill for design weaknesses.✓ 已复制
skillcheck-free-skill + awesome-claude-skill-2

Validate before submitting your skill to the catalog

SkillCheck my SKILL.md, then if clean, draft the awesome-claude-skills PR.✓ 已复制

成本与限制

运行它的成本

API 配额
None
每次调用 Token 数
Small — typical SKILL.md is <10k tokens
费用
Free tier only; Pro tier exists for deeper pattern validation
提示
Free tier is sufficient for most authoring — upgrade only if you publish commercially.

安全

权限、密钥、影响范围

凭据存储： No credentials — pure prompts
数据出站： None — validation is local

故障排查

常见错误与修复

SKILL.md frontmatter wrong in target skill

Expected — that's the finding SkillCheck exists to surface. Fix the frontmatter and re-run.

验证： head <target>/SKILL.md
Wrong trigger keywords — SkillCheck runs but misses severity tier

Ask explicitly for 'severity-tiered output'; default may compress.
