Developer Feedback

I was curious how you'd handle integrating devtools into the Next.js ecosystem—the timing hints at solving some real pain points in the developer experience, but the implementation seems to be missing some structural decisions that would make it production-ready.

The TL;DR

You're at 67/100, which puts you in D territory. This is graded against Anthropic's skill best practices—specifically their Progressive Disclosure Architecture (PDA) standards. Your strongest area is Spec Compliance (12/15), but Utility is dragging you down hard at 11/20. The good news? You've got a solid foundation; you're just missing the structural pieces that would make this actually useful at scale.

What's Working Well

  • Spec compliance is solid — your frontmatter is valid YAML with all required fields, and the hyphen-case naming convention is correct
  • Clear trigger phrases — terms like "Next.js debugging," "inspect routes," and "component tree inspection" are discoverable and specific
  • Good troubleshooting table — having a dedicated section with common issues shows you're thinking about user pain points
  • Concrete command examples — you provide actual bash commands users can run, which is better than abstract explanations

The Big One: Missing Scripts and Layered Structure

Here's what's holding you back the most: you reference scripts (scripts/start-server.sh, scripts/mcp-client.py) that don't exist in your skill package, and everything lives in a single 103-line SKILL.md file with no supporting documentation.

Why it matters: Users can't actually run your examples. When they try bash scripts/start-server.sh, it fails. That breaks trust immediately.

The fix: Either include the actual s...
