Conciseness

The WordPress 7.0-specific material (RTC removal, AI Client, Abilities API, MCP) earns its tokens, but generic boilerplate Claude already knows is inlined: standard theme/plugin directory trees, 'Implement caching (object, page, browser)', 'Minify and combine assets', 'Strong passwords enforced', 'Regular backups configured', and a wp-config.php code block containing only comments. Heavy inline version/date detail (e.g. 'shipped May 20, 2026... April 9 date slipped') further inflates the body.

Actionability

Most guidance is executable and copy-paste ready: full register_post_meta() calls, fluent wp_ai_client_prompt() chains, Abilities API registration on the correct hooks with a complete handler, and concrete MCP server JSON configs. Minor gaps remain, e.g. 'labels' => [...] placeholder, an undefined get_books callback, and the WooCommerce example whose class body is just '// Custom product implementation'.

Workflow Clarity

Eight clearly sequenced phases with numbered actions, per-phase checklists, a Quality Gates section gating phase transitions, and an explicit 'wp plugin check with 0 errors and 0 warnings' verification. Not a 5 because deployment and database migration steps lack explicit validate-fix-retry feedback loops ('Set up database migrations... Deploy to production... Monitor post-deployment' has no checkpoint between migration and deploy).

Progressive Disclosure

The body is a ~560-line monolith with no bundle files (references/, scripts/, assets/ are absent) and no one-level-deep references; substantial reference-grade material (full Abilities API example, AI Client API variations, MCP connection configs) is inlined in SKILL.md. Section headers are well organized and the 'Related skills' pointers exist, but content that should be split into separate files is inline, matching the 'some structure but could be better organized' anchor rather than the 4-5 anchors which require well-signaled file references.

Specificity

Concrete actions are enumerated comprehensively — 'building, extending, auditing, or modernizing WordPress sites end to end' — across named domains (themes, plugins, WooCommerce, performance, security hardening) plus named 7.0 features (AI Client, Abilities API, PHP-only blocks, DataViews). This matches the 'multiple specific concrete actions; comprehensive coverage' anchor and exceeds the 4 anchor, which allows coverage gaps.

Completeness

Explicitly answers 'when' with a 'Use when...' clause listing concrete triggers, answers 'what' ('entry point that routes to the three focused WordPress skills' plus the enumerated capabilities), and even adds negative scope ('Do not use for non-WordPress PHP, or front-end work with no WordPress involvement'). Clearly matches the top anchor.

Trigger Term Quality

Strong natural keyword coverage: 'WordPress', 'themes', 'plugins', 'WooCommerce', 'performance', 'security hardening', 'WordPress 7.0'. Falls short of the 5 anchor ('comprehensive coverage... including synonyms and file extensions') because common variants are absent, e.g. 'WP', 'store/e-commerce setup', 'migration', or 'headless' — users do say these when they need WordPress help.

Distinctiveness Conflict Risk

Clear WordPress-only niche with an explicit exclusion clause ('Do not use for non-WordPress PHP, or front-end work with no WordPress involvement') and explicit routing relative to the three sibling WordPress skills, so it is unlikely to trigger for the wrong skill. Matches the 'clear niche with distinct triggers; minimal conflict risk' anchor.
