85%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a strong skill with excellent actionability through concrete, executable examples covering multiple failure types in both Isabelle and Coq. The workflow is well-structured and the progressive disclosure is appropriate. The main weakness is some verbosity in sections like 'Best Practices' and 'Diagnostic Questions' that restate obvious guidance or duplicate the workflow content.
Suggestions
Remove or significantly condense the 'Best Practices' section - items like 'Read error messages carefully' and 'Check types first' are obvious to Claude and already covered in the workflow
Consolidate 'Diagnostic Questions' into the Step 3 analysis section rather than repeating similar content separately
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is reasonably efficient but includes some unnecessary verbosity, such as the extensive 'Best Practices' section with generic advice Claude already knows (e.g., 'Read error messages carefully') and the 'Diagnostic Questions' section that largely restates the analysis workflow. | 2 / 3 |
Actionability | Provides fully executable code examples for both Coq and Isabelle, with concrete failing proofs, exact error messages, clear explanations, and working solutions. The examples are copy-paste ready and demonstrate real failure scenarios. | 3 / 3 |
Workflow Clarity | The 5-step analysis workflow is clearly sequenced (Gather Context → Identify Category → Analyze Root Cause → Explain → Suggest Solutions) with explicit checkpoints. The quick diagnosis table provides efficient triage for common issues. | 3 / 3 |
Progressive Disclosure | Well-structured with clear overview, detailed examples inline where needed, and appropriate references to external files (failure_patterns.md) and documentation. Navigation is clear with a quick diagnosis table for fast lookup. | 3 / 3 |
