Developer Feedback

I took a look at your shell-scripting-fundamentals skill and wanted to share some thoughts.

The TL;DR

You're at 80/100, solid B-grade territory. This is based on Anthropic's best practices for agentic skills. Your strongest area is Spec Compliance (12/15) — the foundational structure is there. The weakest area is Progressive Disclosure Architecture (20/30) — you've got good content, but it's packed into one flat file without a clear layered structure.

What's Working Well

  • Clear spec compliance – Your YAML frontmatter is valid and the hyphenated naming convention is spot-on. Minor formatting tweaks only.
  • Solid examples – You've got good code examples showing patterns (variables, conditionals, functions). The Good/Bad comparisons are helpful for developers.
  • Realistic scope – Your allowed-tools list gives clear boundaries for what the skill covers. Developers know exactly what they're getting.
  • Objective, technical voice – No marketing fluff. Instructions are imperative and easy to follow.

The Big One

Your file is 221 lines with zero navigation. When a skill goes over 100 lines without a table of contents, developers scroll past critical sections without finding them. More importantly, you're missing a layered structure — everything's crammed into SKILL.md when you should extract detailed examples to a references/examples.md file. This impacts your Progressive Disclosure Architecture score significantly (you're at 20/30; this could get you to 25+).

The fix: Add a TOC right after your title, then create references/examples.md with detailed patterns and move the verbose exampl...
