Developer Feedback
I found your textmate-grammar skill while evaluating the latest batch, and I'm impressed by how thoroughly you've documented the grammar system—the way you break down scope rules and pattern matching is something most people gloss over. With a solid 91/100, there's just a handful of things that could push this to that next level.

The TL;DR
You're at 91/100, A territory—this is production-ready work. The evaluation is based on Anthropic's best practices for agent skills. Your strongest area is Ease of Use (23/25) with crystal-clear metadata and workflow progression, but you're leaving a few points on the table in Progressive Disclosure Architecture (26/30) where the reference structure could be tighter.
What's Working Well
- Reference architecture is solid. You've got scopes.md and regex.md as clean one-level-deep references—exactly what the PDA pattern calls for. Users don't have to dig through nested references.
- Examples are practical and dense. The JSON patterns in your Quick Start aren't bloated; they show real input/output pairs that someone can actually use immediately.
- Terminology is consistent throughout. You use "patterns," "scopes," "captures," and "repository" the same way across all files—no confusion about what you mean.
- Testing section gives real validation. The "Developer: Inspect Editor Tokens and Scopes" command is solid feedback loop material; users know exactly how to verify their work.
The Big One
Your reference files (scopes.md especially at 145 lines) are missing a table of contents. This is a straightforward fix that nets you +1 point. Add a TOC section right after the header:
# TextMate Scope Naming
## Table of Contents
- [Standard Scope Categories](#stan...
