85%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A lean, well-organized codebase reference with clear sequencing and validation guidance. Its main gap is actionability: the 'add a new MIME type' workflow omits the concrete registration call and a DocumentExtractor trait example, leaving two steps as directives rather than copy-paste-ready code.
Suggestions
Show the concrete registration call in 'Adding New MIME Types' (e.g. the exact registry.register(...) line used inside register_default_extractors()) so step 3 is executable rather than a pointer.
Add a minimal DocumentExtractor trait impl skeleton (with supported_mime_types() returning the new MIME) so step 2 is concrete instead of a directive.
Add a verification checkpoint to the add-MIME workflow (e.g. 'validate_mime_type("application/x-new") returns true, then select_extractor_for_mime routes correctly') to confirm the new type is wired end-to-end.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean — tables, terse rules, and code blocks — with no padding explaining what MIME types or registries are; every line is codebase-specific, matching the score-3 'every token earns its place' anchor. | 3 / 3 |
Actionability | Provides exact function names, file locations, and a real insert snippet, but the 'Register in register_default_extractors()' step shows no registration call and 'Implement DocumentExtractor…' is a directive without a trait example — missing key details that fit the score-2 rather than the copy-paste-ready score-3 anchor. | 2 / 3 |
Workflow Clarity | The detection flow is a clearly sequenced pipeline (Extension -> EXT_TO_MIME -> validate -> Registry -> Extractor) and Critical Rules #1 mandates validate_mime_type() before extraction; as a self-contained reference skill with clear sequencing and an explicit validation rule it meets the score-3 simple-skills bar. | 3 / 3 |
Progressive Disclosure | A roughly 50-line self-contained reference with no external files needed, organized into clear headed sections (Detection Flow, Key Functions, Registry Selection, etc.), matching the score-3 guideline for short skills needing no external references. | 3 / 3 |
