tdd-guide

I've been working through TDD implementations lately, and your guide hits on something I've been thinking about—the gap between understanding the concept of test-first and actually making it stick in a team workflow. The C grade seems to nail it: solid foundations, but there's room to tighten up how the progression guides someone from "why TDD?" to "I'm actually doing it.

The TL;DR

You're at 72/100, solidly in C territory. The grading is based on Anthropic's best practices for agentic skills—Progressive Disclosure Architecture, ease of use, compliance, and utility. Your strongest area is Utility (16/20)—the skill actually solves real TDD problems. Weakest link is Writing Style (5/10)—there's promotional language and voice inconsistencies dragging you down.

What's Working Well

• Problem-solving power is legit (7/8 for utility). You're addressing real needs: test generation from requirements, coverage analysis, multi-framework support. The shopping cart example actually demonstrates something useful.
• Solid structure underneath (6/10 for layered structure). Having HOW_TO_USE.md and README.md shows you're thinking about depth. The red-green-refactor validation loop is exactly what someone needs.
• Bonus points for grep-friendly structure (+1 modifier). You've built this thoughtfully enough that grep works well, and the scope boundaries are explicit.

The Big One: SKILL.md is Too Heavy

Your main drag is Progressive Disclosure Architecture (18/30)—specifically the token economy. SKILL.md is 288 lines when it should be a tight overview. Right now you're duplicating content from HOW_TO_USE.md and README.md inside SKILL.md itself. That's backwards.

Here's the fix: Cut SKILL.md down to ~100 lines. Keep:

• Metadata (frontmatter)
• One-liner capability summary
• "See HOW_TO_USE.md for examples" pointers
• Input requirements section

Move everything else—the verbose "Capabilities" section, the 8-module breakdown, the framework details—into HOW_TO_USE.md. This alone gets you +4 points on token economy and fixes the navigation issue (missing TOC).

Other Things Worth Fixing

1. Add explicit trigger phrases (Medium impact, +2-3 points). Right now the description is passive ("Comprehensive Test Driven Development guide..."). Change it to: "Test Driven Development guide. Use when: 'generate tests', 'analyze coverage', 'TDD workflow', 'Jest tests', 'Pytest tests'." This fixes discoverability instantly.

2. Strip the marketing voice (Medium impact, +2 points). Phrases like "transforms how engineering teams," "Ready to improve," and "best results" need to go. Rewrite to: "Test Driven Development skill for test generation, coverage analysis, and TDD workflow guidance." Just facts, no sizzle.

3. Standardize terminology (Quick win, +1 point). You're mixing "test cases" vs "test scenarios" and "framework" vs "testing framework." Pick one per concept and stick with it throughout.

4. Fix the voice inconsistency (Quick, +2 points). Lines like "your environment" and "you can use" should be imperative: "optimized for environment," "use." Removes the second-person creep.

Quick Wins

1. Trim SKILL.md, move content to HOW_TO_USE.md → +4 points
2. Add trigger phrases to metadata → +2-3 points
3. Remove marketing language and keep it technical → +2 points
4. Pick one term per concept (test case, framework) and stick → +1 point

Hitting these four gets you close to 85/100. The skill has good bones—your TDD workflow logic is solid. It just needs the cruft cleaned out so people can actually use it without wading through marketing copy.
