The TL;DR

You're at 96/100 — that's solid A-grade territory. This is graded against Anthropic's skill best practices, and your strongest area is Spec Compliance (15/15 — literally perfect there). The PDA architecture is really clean too at 27/30. The gaps are small: missing TOCs in reference files and a couple of workflow examples that would push this even higher.

What's Working Really Well

• Spec Compliance is locked in — Your YAML is valid, naming conventions are correct (hyphen-case), and your description nails the trigger coverage with phrases like 'write Python', 'pytest', 'FastAPI', 'async', 'Pydantic'. That's exactly what discoverability looks like.

• Token economy is tight — SKILL.md stays lean at 117 lines while your 4 reference files pack 45 chapters of Python depth. You're not making people load everything; they get the nav first, then drill into what they need. That's Progressive Disclosure done right.

• Triggers are really solid — You've got 6+ trigger phrases covering the real work developers do. That means Claude agents will actually find this when they need it.

• Quality validation checklist — The Quickstart Checklist with smoke tests and the validation patterns table give people a way to verify their work. That's practical.

The Main Issue

Your reference files need Tables of Contents. Right now, files like part1-chapters.md and advanced-python.md run 150-236 lines with no TOC, so someone reading a reference file has to scroll through to find what they're looking for.

The fix: Add a simple ## Contents section at the top of e...
