78%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 exceptionally concise and well-structured for a small single-purpose skill, with a clear sequence and an implicit test-based feedback loop; its main weakness is that the scraping/parsing mechanics are described rather than shown as executable code.
Suggestions
Add a short, concrete code snippet showing the selector-based parsing (e.g., the tr.athing extraction into the Story record) so the actionability of the scraping step matches the run command.
Make the validation/feedback loop explicit in the workflow (e.g., 'If parsing returns 0 stories, the HN HTML layout likely changed; regenerate the fixture and update selectors') rather than relegating it to the rationale section.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and assumes Claude's competence: a short usage block, a four-step 'How it works' list, and a brief rationale with no padding or explanation of basic concepts, matching anchor 5 ('lean and efficient; every token earns its place'). Not 4 because there is no over-explanation to trim. | 5 / 5 |
Actionability | It gives an executable invocation ('$B skill run hackernews-frontpage') and a concrete sample JSON output, but the core scraping logic is described abstractly ('Reads the page HTML', 'Parses each story row') with no executable code for the actual parsing, matching anchor 3 ('some concrete guidance but incomplete'). Not 4 because there is no copy-paste parsing code; not 2 because the run command and output schema are concrete. | 3 / 5 |
Workflow Clarity | The 'How it works' list is a clear four-step sequence (navigate, read HTML, parse rows, emit JSON), and the fixture/test feedback loop ('the test fails against the captured fixture before users notice') acts as an implicit validation checkpoint, matching anchor 4 ('clear sequence with most checkpoints present; minor validation gaps'). Not 5 because validation is described as an external test rather than an explicit in-workflow validate->fix->retry step; not 3 because the sequence is clear and a feedback mechanism is present. | 4 / 5 |
Progressive Disclosure | This is a simple skill under 50 lines with no bundle files (references/scripts/assets all absent) and well-organized sections (Usage, How it works, Why), so per the simple-skill scoring note it qualifies for anchor 5; the content is appropriately self-contained with no nested or buried references. Not 4 because there are no organization gaps given the size. | 5 / 5 |
