Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
skillcheck-free
SkillCheck Free validates Claude Code SKILL.md files against ~25 contract rules covering structure, naming, semantic consistency, and quality patterns. It catches missing frontmatter, weak or ambiguous descriptions, trigger collisions, anti-pattern formatting (prose where tables belong), naming smells, and contradictions before users encounter them. Runs locally — it's itself a SKILL.md the agent reads, with no API calls, binaries, or external services. MIT-licensed. Works in Claude Code, Claude Desktop/Web (Projects), and Cursor. The Free tier covers structural, semantic, and naming checks plus quality-pattern recognition. SkillCheck Pro (separate product at getskillcheck.com) adds anti-slop detection, security scanning, token budget analysis, WCAG accessibility, and enterprise readiness checks.
