71%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 a well-structured, token-efficient overview that correctly pushes implementation detail into a single one-level-deep reference file. Its weaknesses are repetition of the soft-404 point across three sections, an opener explaining a concept Claude already knows, and Check/Fix guidance that names what to verify without any concrete verification commands in the body itself.
Suggestions
State the HTTP-404/soft-404 requirement once (e.g., in Check) and drop the repetitions in Quick Reference and Fix.
Add one concrete verification command to the Check section, such as "Confirm `curl -I https://site/nonexistent` returns 404, not 200" so the body is directly executable.
Trim the opening sentence explaining why generic 404 pages lose users — Claude already knows this — and lead with the check itself.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean with well-organized sections, but the HTTP-404/soft-404 point is repeated three times ("Return a real HTTP 404", "Confirm the route returns HTTP 404 and not a branded page with a 200 response", "Ensure the server or framework returns status code 404"), and the opener explains why custom 404 pages matter — a concept Claude already knows. Minor trimming would reach anchor 5. | 4 / 5 |
Actionability | The Check and Fix sections give directive, domain-specific guidance ("Verify that this website has a custom 404 error page with helpful navigation options", "Confirm the route returns HTTP 404"), but the body contains no concrete commands or examples — e.g., how to actually test the status code or what markup to inspect. All executable specifics are deferred to references/rule.md, leaving the body's guidance incomplete, which fits anchor 3 rather than the executable-guidance profile of anchor 4. | 3 / 5 |
Workflow Clarity | The Check → Fix → Explain → Code Review structure gives a coherent sequence for a simple review skill, and the Check section acts as the validation checkpoint, so the destructive-operation cap does not apply. It falls short of anchor 5 because the "Check" and "Code Review" sections overlap without an explicit ordering of what to do when a violation is found. | 4 / 5 |
Progressive Disclosure | The body is a short overview with a clearly signaled, one-level-deep reference — "For full implementation details, code examples, and framework-specific guidance, see references/rule.md" — and that file exists and appropriately holds the bulk material (code examples, framework implementations, verification steps). This matches the anchor for a clear overview with well-signaled one-level-deep references and easy navigation. | 5 / 5 |
