Author: olgasafonova

автор 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.

Сценарии использования

Реальные сценарии: SkillCheck-Free

Validate your skill before publishing it to a catalog

👤 Skill authors ⏱ ~20 min beginner

Когда использовать: Before opening a PR to awesome-claude-skills or anthropics/skills.

Поток

Run SkillCheck on your SKILL.md

Use SkillCheck-Free — validate ~/my-skill/SKILL.md against the agentskills spec.✓ Скопировано

→ Per-rule findings with severities
Fix Critical issues

Walk me through each Critical finding and propose a fix.✓ Скопировано

→ Concrete edits, not 'improve clarity'
Re-run until clean

Re-validate. Anything still Critical or Warning?✓ Скопировано

→ Progress toward zero Critical

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

Подводные камни

Chasing every Suggestion — Suggestions are aspirational; Critical + Warning is the bar for most catalogs

Сочетать с: 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

Когда использовать: You installed 20 skills and aren't sure which ones are well-made.

Поток

Decide what to keep

Which skills have persistent Critical issues I should uninstall?✓ Скопировано

→ Prioritized uninstall candidates

Итог: A leaner, higher-quality skill collection.

Комбинации

Сочетайте с другими MCP — эффект x10

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.✓ Скопировано

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.✓ Скопировано

Инструменты

Что предоставляет этот MCP

Инструмент	Входные данные	Когда вызывать
validate_skill	path to SKILL.md	Pre-publish or post-install
classify_pattern	skill body	Understanding how a skill fits your collection
batch_validate	directory of skills	Fleet-wide audit

Стоимость и лимиты

Во что обходится

Квота API: None
Токенов на вызов: Small — typical SKILL.md is <10k tokens
Деньги: Free tier only; Pro tier exists for deeper pattern validation
Совет: Free tier is sufficient for most authoring — upgrade only if you publish commercially.

Безопасность

Права, секреты, радиус поражения

Хранение учётных данных: No credentials — pure prompts

Исходящий трафик: None — validation is local

Passing SkillCheck ≠ the skill is actually useful; it's a spec check, not a utility check.

Устранение неполадок

Частые ошибки и исправления

SKILL.md frontmatter wrong in target skill

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

Проверить: head <target>/SKILL.md

Wrong trigger keywords — SkillCheck runs but misses severity tier

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

Альтернативы

SkillCheck-Free в сравнении

Альтернатива	Когда использовать	Компромисс
skills-skill-8 auto-test-skill	You want design robustness testing, not spec compliance	Complementary — run both
Manual review	You've written many skills and have internalized the spec	No machine backstop for subtle issues
