100%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is an exceptionally well-crafted skill that demonstrates mastery of the format. It provides high-value, actionable VCL recipes targeting genuinely error-prone patterns (Vary header append, cookie parsing, grace detection), includes critical safety guidance (token handling, pre-flight checks), and organizes 20+ topic areas into a clean progressive disclosure table. The common mistakes section alone would prevent numerous silent 503 errors and debugging sessions.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient throughout. It assumes Claude's competence with VCL, CDN concepts, and API usage. Every section earns its place — the VCL recipes address genuinely tricky gotchas (grace detection, Vary append, cookie parsing) rather than explaining basic concepts. The 'Common Mistakes' section is a high-value, compact list of non-obvious pitfalls. | 3 / 3 |
Actionability | All VCL recipes are fully executable, copy-paste ready code with correct syntax. The pre-flight checks provide specific curl and openssl commands. Each recipe includes not just the code but the critical context about where it must be placed (e.g., vcl_fetch vs vcl_deliver) and why alternatives fail. The common mistakes section provides concrete corrections. | 3 / 3 |
Workflow Clarity | The Quick Start section provides a clear sequenced workflow with explicit pre-flight validation checks (verify origin responds, check TLS SANs) before any configuration. The VCL recipes each include clear placement guidance and warnings about incorrect approaches. The skill appropriately delegates the full step-by-step workflow to the CLI skill's reference, keeping this skill focused. | 3 / 3 |
Progressive Disclosure | Excellent progressive disclosure with a well-organized topic table providing 20+ one-level-deep references with clear 'Use when...' descriptions. The main SKILL.md contains a concise overview, common recipes, and quick start, while detailed topics are cleanly separated into reference files. Navigation is intuitive with the table format. | 3 / 3 |
