Conciseness

The body is lean: terse bullet lists, concrete file paths, and only non-obvious domain gotchas ("user customizations can make theme.json edits appear 'ignored'", "parts must not be nested in subdirectories"). It assumes Claude's competence and every section earns its place; not below 5 since no padded or redundant explanation was found.

Actionability

Concrete commands ("node skills/wp-block-themes/scripts/detect_block_themes.mjs") and exact file locations (templates/, parts/, patterns/, styles/) make the guidance mostly executable. Not 5 because the triage step references an external cross-skill script ("skills/wp-project-triage/scripts/detect_wp_project.mjs") that is not in this bundle, and the theme.json steps have no inline example — though the latter is legitimately deferred to references.

Workflow Clarity

Steps 0–6 are clearly sequenced with a dedicated Verification section and a Failure modes section for error recovery. Not 5 because checkpoints are section-level rather than inline per-step validation (e.g., no 'validate theme.json syntax after editing' checkpoint, and verification items are checks to observe rather than commands to run); not 3 since verification and feedback direction are explicitly present.

Progressive Disclosure

Each section ends with a well-signaled one-level-deep pointer ("Read: references/theme-json.md" etc.), and all six referenced files plus the detect_block_themes script exist in the bundle with matching purpose statements. The overview is concise and navigation is easy; not below 5 as no content that belongs in a reference is inlined and no nesting exceeds one level.

Specificity

"theme.json (global settings/styles), templates and template parts, patterns, style variations, and Site Editor troubleshooting (style hierarchy, overrides, caching)" lists multiple specific concrete capability areas with comprehensive coverage of the block-theme domain. Not below 5 because nothing significant in the domain is omitted; not applicable above.

Completeness

Explicitly answers when ("Use when developing WordPress block themes") and what via the enumerated scope after the colon. Not 5 because the 'what' is a topic list rather than an explicit statement of actions performed (e.g., 'edits', 'creates', 'debugs'), so it is present but slightly less explicit than the anchor-5 form; clearly above anchor 3 since both what and when are stated.

Trigger Term Quality

Strong natural terms users would say: "WordPress block themes", "theme.json", "patterns", "style variations", "Site Editor", "troubleshooting". Not 5 because common synonyms like "FSE", "full site editing", or "Gutenberg" are absent, leaving a few natural trigger variations uncovered.

Distinctiveness Conflict Risk

"WordPress block themes" carves out a clear niche with distinct triggers (theme.json, Site Editor, style variations) and minimal conflict risk against other WordPress skills. No neighboring anchor fits better.
