I took a look at your c-systems-programming skill and wanted to share some thoughts.

The TL;DR

You're at 78/100 — solid C-grade work. This is based on Anthropic's skill best practices rubric. Your Writing Style is chef's kiss (10/10), and the practical examples are genuinely helpful. The weak spots are Progressive Disclosure Architecture (18/30) and missing structural elements that would make this easier to navigate and reuse.

What's Working Well

• Writing is clean and direct — No fluff, proper imperative voice, reads like someone who actually knows systems programming
• Solid code examples — Your patterns show real-world C systems problems (memory management, file I/O, error handling)
• Good metadata — Name follows conventions, description has clear trigger phrases like "pointer management", "systems programming"
• Comprehensive coverage — You're hitting the major pain points developers face with C

The Big One: Missing References Directory

Here's what's holding back your score the most: You have no external references directory, and your 800+ line skill file lacks a table of contents. This is costing you 5 points straight up.

Why it matters: When devs use your skill, they're jumping around a wall of text trying to find what they need. Progressive Disclosure Architecture is about layering information so people find what's relevant first, not scrolling forever.

The fix:

1. Create a references/ directory at the skill root
2. Break out detailed topics into separate markdown files (e.g., memory-management-patterns.md, signal-handling-guide.md)
3. Add a Table of Contents at the top of SKILL.md with links to sections
4. Link from the main skill into...
