jest-testing

I've been diving through testing skills lately, and I noticed your jest-testing skill handles some real-world patterns that a lot of tutorials gloss over—the B grade reflects solid execution with room to polish the developer experience.

The TL;DR

You're at 87/100, solidly in B territory. This is based on Anthropic's best practices for skill design. Your strongest area is Utility (18/20)—the skill solves real problems for testing interpreters and async patterns. The weakness is Progressive Disclosure Architecture (24/30)—your documentation structure could guide developers through patterns more efficiently without the overhead.

What's Working Well

• Practical triggers: Your metadata nails discoverability with specific phrases like "writing Jest tests" and "testing patterns"—developers will actually find this when they need it
• Smart reference organization: Delegating mocking and async patterns to separate files is the right call; keeps SKILL.md lean while letting people dive deeper when needed
• Real-world examples: The Arrange-Act-Assert pattern examples and mock implementations actually match what people write, not textbook pseudocode
• One-level-deep references: No nested reference chains—clean dependency graph that respects token economics

The Big One: Missing Navigation Structure

Your SKILL.md (107 lines) and reference files (mocking.md at 117 lines, async-testing.md at 119 lines) lack tables of contents. This matters because it burns tokens on scrolling through dense content instead of jumping to what developers need.

The fix: Add a simple TOC at the top of each file:
