Conciseness

Largely lean — every section adds domain-specific judgment rules Claude would not infer on its own (e.g. 'Treat these as separate signals: negotiated markdown works / a stable direct markdown URL works / the page advertises the correct markdown URL'). It falls short of 5 because of repetition: the docs-only-host caveat appears in section 1, again in section 2, and again in Notes ('Do not fail a docs host for lacking MCP or plugin manifests'), and the live-fetch-over-source-tree principle is stated in both the intro and section 7. A 3 would require noticeable padding or explanation of concepts Claude already knows, which is not the case.

Actionability

Concrete throughout: exact paths to probe (/llms.txt, /robots.txt, /.well-known/ai-plugin.json), copy-paste-ready bash invocations of the bundled script including the CHECK_TOOL_MANIFESTS=0 variant, a hard sample floor ('Sample at least 12 pages'), enumerated page types, and a P0/P1/P2 remediation format. It stops short of 5 because the per-page fetch checks in section 4 name what to verify ('Accept: text/markdown behavior', 'redirect chain length and canonical URL consistency') without providing runnable commands or expected output shapes, and criteria like 'obvious chrome/noise' and 'closely enough for retrieval parity' are left as qualitative judgment. A 3 would mean pseudocode or high-level hints only, which underrates the specificity present.

Workflow Clarity

The nine numbered sections form a coherent pipeline (scope → sitewide signals → sampling → per-page checks → judgment → scoring → external comparison → remediation → report), with explicit validation and recovery loops: 'If the sitemap is missing or unusable, discover pages through internal links and note the lower confidence', and the scanner-disagreement rule 'trust the live fetch, report the mismatch explicitly'. Scoring integrity rules ('score only what you verified', 'mark non-applicable checks as N/A', 'normalize the final score against applicable points only') act as checkpoints, and the rubric's foundational caps prevent averaging away weak segments. This matches the 5 anchor's sequence-with-feedback-loops-and-checklists; the read-only audit means the destructive-operation cap does not apply.

Progressive Disclosure

The body is a navigable overview with clearly headed sections, and heavy material is correctly externalized: the scoring rubric lives in references/rubric.md and the output format in references/report-template.md, both linked at their point of use in sections 6 and 9, and both verified to exist with no nested references (one level deep). The bundled script is invoked by path and exists at scripts/baseline-probes.sh. This is the 5 anchor's 'clear overview with well-signaled one-level-deep references'; a 4 would require organization gaps or buried references, and none are present.

Specificity

The description lists multiple concrete actions — 'Audit a documentation site for agent-friendliness: discovery, markdown delivery, crawlability, semantic structure, machine-readable surfaces, and content legibility', 'produce a scored report, compare with external scanners, or generate a remediation list' — covering the workflow comprehensively. This matches the 5 anchor ('multiple specific concrete actions; comprehensive coverage') and exceeds the 4 anchor, which expects minor coverage gaps; none are evident.

Completeness

Both halves are explicit: the 'what' enumerates the audit dimensions and outputs, and the 'when' is a dedicated 'Use when asked to...' clause followed by concrete trigger phrases. This is the 5 anchor verbatim in structure; a 4 would mean the 'when' clause were present but less specific.

Trigger Term Quality

The 'Triggers on:' line gives natural user phrasings — "audit docs for agent readiness", "how agent-friendly is docs.docker.com", "score our docs for AI agents", "review llms.txt / markdown / crawlability", "create an agent-readiness remediation plan" — plus synonyms (agent-friendly, AI/agent readiness, agent-readiness) and technical surface terms (llms.txt, crawlability). Comprehensive natural-term coverage; a 4 would require visible missing variants, and none stand out.

Distinctiveness Conflict Risk

It carves a clear niche — agent/AI-readiness auditing of documentation sites — with triggers naming llms.txt, crawlability, and agent-friendliness that no adjacent skill (general web review, SEO audit) would claim. Minimal overlap risk; not the 4 anchor, which expects some overlap with closely related skills.
