86%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.
The body is an exemplary internal-reference skill: dense with non-obvious, codebase-specific facts (security budget threading, feature gates, registry invariants like 'do not hand-edit EXT_TO_MIME') organized into scannable per-format sections. Its only minor weakness is that some workflows stop at 'add tests' without an explicit verification checkpoint.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is a lean codebase map with zero concept explanations — e.g. 'the engine takes an owned Vec<u8>, not a slice' and 'The Office path does not use ZipBombValidator'. Every token is repo-specific fact Claude could not know otherwise, matching 'Lean and efficient; every token earns its place'. | 5 / 5 |
Actionability | Concrete functions, file paths, and API calls throughout ('ZipBombValidator::new(limits).validate(&mut archive)? before any extraction', exact config member names, real helper locations). It falls short of anchor 5's copy-paste-ready code because much guidance is pointer-style with occasional pipeline shorthand ('ZIP archive → SecurityBudget → XML parsing'). | 4 / 5 |
Workflow Clarity | Each format section is a numbered sequence with a validation gate (ZipBombValidator before any extraction, SecurityBudget threading), and the 'Adding a New Format' checklist is an ordered 8-step procedure including tests. It is not 5 because steps like 'Add tests with fixture files' lack an explicit verify/retry checkpoint after registration. | 4 / 5 |
Progressive Disclosure | Each per-format section is a concise overview pointing one level deep to concrete files ('See extractors/docx.rs', the Common Helpers table with exact locations), plus clearly signaled sibling skills. No bundle files exist to be misorganized, and navigation between sections is trivial — matching 'Clear overview with well-signaled one-level-deep references'. | 5 / 5 |
