Areas to Improve

  • Missing TOC in publishing.md

Recommendations

  • Add trigger phrases to description for discoverability
  • Add table of contents for files over 100 lines

Developer Feedback

I've been exploring how extension marketplaces handle the discovery problem, and your skill's approach to surfacing developer tools caught my attention—especially with that A-grade score backing it up. The way you've structured the guidance here suggests you've thought deeply about reducing friction for first-time extension developers.

The TL;DR

You're at 92/100, solid A territory. This is graded against Anthropic's best practices for skill design. Your strongest pillar is Utility (19/20)—the skill actually solves real problems with complete examples and templates. Weakest is Spec Compliance (12/15), mostly because you're only hitting 1-2 trigger phrases instead of a richer set.

What's Working Well

  • Utility is chef's kiss – The grammar structure guidance, language configuration examples, and publishing checklist are genuinely useful. You've got concrete input/output pairs and templates that developers can actually use.
  • Progressive Disclosure nailed – Three reference files (textmate.md, language-config.md, publishing.md) sit exactly one level deep from the main skill, and the token density is tight with zero fluff.
  • Trigger terms are solid – Phrases like "TextMate grammars" and "language configuration" will surface this for the right use cases. The description connects clearly to VS Code extension development.
  • Publishing checklist is structured – Numbered steps and validation checkpoints give developers a clear path to market.

The Big One: TOC Gap in Reference Files

Your three reference files (143, 157, and 151 lines) lack tables of contents. For a developer scanning textmate.md looking for "scope naming conventions," they're doing ctrl+F instead of jumping via TOC. This hurts discove...
