Conciseness

The project-specific material (commands, envelope schema, scoring weights, error handling) is dense and earns its tokens, but the 'Report Structure' section lists generic SEO checklists Claude already knows ('Title tag issues', 'Missing alt text', 'E-E-A-T assessment') and the Crawl Configuration block duplicates limits already stated in step 3. Not a 4: these are several removable sections, not minor trimmings; not a 2: most of the body is non-obvious, project-specific guidance rather than padding.

Actionability

Fully executable guidance throughout: exact invocation commands ('"${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run render_page.py <url> --mode auto --json'), concrete output paths ('{domain}-audit/FULL-AUDIT-REPORT.md'), a complete copy-ready JSON envelope schema, a scoring weights table, and explicit conditional spawn conditions with auth-check commands. Specific examples cover the common cases.

Workflow Clarity

A clear 7-step sequence with explicit error-recovery feedback loops: the Error Handling table prescribes actions for unreachable URLs, robots.txt blocks, rate limiting, timeouts, and partial subagent findings ('Read whatever findings file exists and merge it into the report'). Conditional spawn rules (spawn when Local Service detected, when credentials check passes) act as checkpoints. This matches the anchor-5 example's validate-and-recover pattern adapted to an audit context.

Progressive Disclosure

No bundle files exist (references/, scripts/, assets/ are absent), so everything — the ~40-line JSON envelope schema, the Report Structure checklists, and four integration sections — is inlined in a single ~200-line SKILL.md. Section headers and a flat structure keep it navigable (not a 2), but content that clearly belongs in separate reference files (the envelope spec, per-integration details) is inline, matching the anchor-3 pattern of '200 lines that could be in a separate file'.

Specificity

Names the domain ('full-site SEO audit') with two concrete actions ('run a full-site SEO audit', 'return a scored, prioritized report'), but coverage stops there — crawling, subagent delegation, and reporting detail are absent. Not a 4: fewer than 'several specific actions'; not a 2: the actions named are concrete, not generic.

Completeness

Has a clear 'what' ('Run a full-site SEO audit and return a scored, prioritized report') and an explicit 'when' clause ('Use only for site-wide checks') plus negative guidance routing to seo-page/seo-technical. Not a 5: the 'when' is a scoping constraint rather than concrete trigger phrases like 'when the user mentions X'; not a 3: an explicit 'Use only for...' clause is present, so the completeness cap of 3 does not apply.

Trigger Term Quality

Good natural keyword coverage — 'SEO audit', 'site-wide checks', 'one URL', 'technical-only review' are phrases users would plausibly say. Not a 5: misses common synonyms/extensions users might say ('website audit', 'SEO check', 'search ranking review'); not a 3: the present terms go beyond a single generic keyword with relevant variations for scope selection.

Distinctiveness Conflict Risk

The description actively disambiguates from sibling skills ('use seo-page for one URL or seo-technical for a technical-only review'), carving a clear niche with minimal conflict risk. The routing guidance is stronger than the anchor-4 'minor overlap risk' case.
