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 document with excellent actionability through complete, executable Isabelle and Coq examples. The workflow is clearly structured with explicit steps and a verification checklist. Minor verbosity in the overview section and some explanatory content that Claude wouldn't need slightly reduces token efficiency.
Suggestions
Remove or significantly condense the Overview section - Claude already knows what proof-carrying code is and doesn't need the numbered list of what the skill generates
The 'Core Approaches' section could be more concise by removing the 'Steps' lists since the examples already demonstrate the workflow clearly
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is reasonably efficient but includes some unnecessary explanatory content like the overview section explaining what PCC is, which Claude would already know. The workflow diagram and some introductory text could be trimmed. | 2 / 3 |
Actionability | Provides fully executable Isabelle and Coq code examples throughout, with complete proof structures, theorem statements, and extraction commands. Examples are copy-paste ready and cover multiple approaches. | 3 / 3 |
Workflow Clarity | Clear multi-step workflows with explicit sequences (specification → implementation → proof → extraction). Includes a verification checklist with explicit validation steps and the workflow diagram clearly shows the process flow. | 3 / 3 |
Progressive Disclosure | Well-structured with clear overview, detailed examples inline, and appropriate references to separate files (isabelle_pcc.md, coq_pcc.md, safety_properties.md) for framework-specific and detailed content. References are one level deep and clearly signaled. | 3 / 3 |
