Conciseness

The body is mostly efficient — the grep.app URL pattern, the '(?s)' regex tip, the 1000+ stars heuristic, and the evaluation table all earn their tokens — but the 'When to Use This Skill' section duplicates the frontmatter description and the three bash blocks contain only comments, fitting anchor 3 ('could be tightened') more than anchor 4's minor instances.

Actionability

Concrete, usable guidance throughout: a real grep.app URL pattern, an executable 'gh search code "getServerSession(" --language=TypeScript' command, site: query examples, a complete output-format template, and a worked rate-limiting example. The example queries sit in comment-only blocks rather than ready-to-run commands and 'Synthesize' is underspecified, so it falls short of anchor 5.

Workflow Clarity

The Search Workflow is a clear numbered 4-step sequence (docs → GitHub → web → synthesize), and the Result Evaluation table plus the 'Over-researching — stop when you have enough' anti-pattern supply quality criteria and a stopping rule. Evaluation is not wired into the workflow as an inline checkpoint step, so it does not reach anchor 5's explicit validation steps.

Progressive Disclosure

A single-file skill with no bundle files and no external references; sections are well-organized with clear headers and nothing that belongs in a separate reference file. The body exceeds 50 lines, so the simple-skill exception to anchor 5 does not strictly apply — anchor 4 ('good structure; most content appropriately placed') is the best fit.

Specificity

The only concrete action is 'searching'; 'across documentation, open-source repositories, and web resources' names the domain's targets but adds no distinct action verbs, matching anchor 3 ('Names domain and 1-2 concrete actions') rather than anchor 4's several specific actions.

Completeness

Both parts are present: 'Systematic external reference searching across documentation, open-source repositories, and web resources' (what) and an explicit 'Use when working with unfamiliar libraries, APIs, or when needing production-quality implementation examples' (when). The 'what' is process-abstract rather than listing concrete actions, keeping it below anchor 5.

Trigger Term Quality

'unfamiliar libraries', 'APIs', 'production-quality implementation examples', and 'documentation' are phrases users would naturally say, giving good keyword coverage; common variations like 'docs', 'examples', or 'best practices' are missing, so it does not reach anchor 5.

Distinctiveness Conflict Risk

'searching across ... web resources' and 'working with unfamiliar libraries' would plausibly also trigger general web-search or research skills, so it fits anchor 3 ('could still overlap with similar skills') rather than anchor 4's minor overlap risk.
