77%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A tight, well-structured review skill: clear check/fix/explain workflow, concrete header-value guidance, and correct use of a one-level-deep reference for implementation details. The main weakness is mild redundancy — the clickjacking attack scenario is explained twice.
Suggestions
Drop one of the two clickjacking explanations — keep either the banking-login narrative in the intro or the Quick Reference bullet, not both.
Add a one-line concrete verification command to the Check section, e.g. `curl -sI https://example.com | grep -i x-frame-options`.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is compact, but the opening banking-login attack narrative explains clickjacking — a concept Claude already knows — and is then restated by the Quick Reference bullet "Clickjacking attacks trick users into clicking invisible iframe buttons — DENY eliminates this entirely". One of the two passages could be cut. | 3 / 5 |
Actionability | Concrete, executable guidance with exact header values and decision rules: "Use X-Frame-Options: DENY... or SAMEORIGIN", "ALLOWFROM is obsolete... use CSP frame-ancestors instead". Minor gap: the Check section never says how to inspect responses (e.g., curl -I or browser devtools). | 4 / 5 |
Workflow Clarity | A simple, single-purpose skill with an unambiguous Check → Fix → Explain → Code Review sequence, and the Code Review section includes an explicit validation checkpoint ("verify them against the effective production-like response"). | 5 / 5 |
Progressive Disclosure | The body is a lean overview and the single reference (references/rule.md, which exists) is clearly signaled, one level deep, holding the implementation details — matching the simple-skill ideal structure. | 5 / 5 |
