mcp-builder

I've been diving into MCP implementations lately, and your approach to wrapping the builder pattern is pretty thoughtful—especially how you handle the validation flow without over-engineering it. Scored a solid 90, so curious what you'd prioritize if you were to iterate on it next.

The TL;DR

You're at 90/100, A territory. This is based on Anthropic's Claude Skills Best Practices. Your strongest area is Ease of Use (23/25)—the trigger terms and workflow clarity are solid. The weakest spot is Spec Compliance (13/15), mainly because you're only using 1-2 trigger phrases when you could be more explicit.

What's Working Well

• Layered structure is chef's kiss. SKILL.md stays tight at 314 lines with 5 focused reference files. That's how you do Progressive Disclosure right—no token waste, but comprehensive when developers dig deeper.
• Your trigger terms nail discoverability. "MCP server," "FastMCP," "Python SDK," "Node SDK"—these activate naturally when someone needs to build something. That's why Ease of Use scored 23/25.
• The 4-phase workflow is clear. Research → Implementation → Testing → Evaluation, each with actionable subsections and checklists. Developers know exactly what phase they're in and what to do next.
• Examples in both Python and TypeScript. Shows you understand your audience isn't monolithic. That adds real utility (18/20 there).

The Big One: Missing Navigation in Long Files

Your reference files are dense—719, 970, 602 lines in some cases—but no table of contents. This kills navigation signals and costs you 2-3 points on Progressive Disclosure.

The fix: Add a TOC right after the frontmatter in SKILL.md and any reference file over 100 lines:

## Contents

- [Phase 1: Research](#phase-1-research)
- [Phase 2: Implementation](#phase-2-implementation)
- [Phase 3: Testing](#phase-3-testing)
- [Phase 4: Evaluation](#phase-4-evaluation)

This takes 10 minutes and gets you to 93/100 territory.

Other Things Worth Fixing

1. Docker section overstay. You've got 65 lines of Docker/containerization details embedded in SKILL.md (lines 240-304). Move this to reference/docker_deployment.md and link it. Keeps the main file tighter and follows your own layering pattern.

2. Second-person voice creeping in. Phrases like "you must start the MCP server" and "your implementation" should be imperative: "Start the MCP server separately" or "Configure the implementation." Small shift, but Writing Style moves from 9/10 to 10/10.

3. Add more trigger phrases to the frontmatter description. You've got good ones, but "MCP transport mechanisms," "tool definition," and "resource registration" would help the skill surface in more searches.

Quick Wins

• Add TOC to files >100 lines (+2 points)
• Move Docker content to separate reference file (+1 point)
• Shift second-person to imperative voice (+1 point)
• Expand trigger phrases in description metadata (+1 point)

That's potentially 95/100 with minimal effort. You're already at A-grade—these are just refinements.
