Conciseness

The body is lean, imperative, and never explains concepts Claude already knows — it matches 'Efficient; minor instances of over-explanation that could be trimmed' rather than the lean-every-token anchor. The image-attachment constraint is restated three times with overlapping item lists (lines 18, 39, and the §3 note), and the 'Preserve the boundary' rules partially overlap the completion checklist; consolidating these would reach level 5.

Actionability

Guidance is fully concrete: an exact validation command ('node <skill-dir>/scripts/validate_capture.mjs <article-dir>/manifest.json'), a copy-paste Markdown image template (''), explicit required manifest fields, and a filled-in brief contract in references/thread-brief-contract.md. For an instruction-only skill this meets 'Fully executable... specific examples cover the common cases'; it is above the level where minor gaps in executable detail exist.

Workflow Clarity

A clear numbered sequence (locate/validate → originality matrix → briefs → create tasks → handoff requirements → report) with an explicit validation gate ('Stop if validation fails'), blocker-reporting rules, task-confirmation via wait/status tooling, and a final 'Completion checks' checklist. This is a batch operation and validation plus feedback on failure are present, matching 'Clear sequence with explicit validation steps; feedback loops for error recovery; checklists for complex processes'.

Progressive Disclosure

The body is a well-sectioned overview that pushes the detailed brief template into references/thread-brief-contract.md (clearly signaled: 'Read [references/thread-brief-contract.md]... before creating any task') and validation logic into scripts/validate_capture.mjs. Both referenced files exist, the reference is one level deep (thread-brief-contract.md points to no further files), and no content that belongs in a separate file is inlined — matching 'Clear overview with well-signaled one-level-deep references'.

Specificity

The description states concrete actions comprehensively: 'Turn a completed daily UI inspiration capture into exactly five original landing-page builds, one per separate Codex task, using Sites' and enumerates exactly what gets replaced ('brands, names, copy, people, numbers, pricing, claims, and imagery'). It matches the anchor 'Lists multiple specific concrete actions; comprehensive coverage' and is not the level below, which only covers 'several specific actions with minor gaps'.

Completeness

Both questions are answered explicitly: the 'what' is turning a five-item capture into five original landing-page builds with full identity replacement, and the 'when' is an explicit 'Use when the user asks to turn...' clause with three concrete trigger objects. This matches the anchor 'Clearly and explicitly answers both what AND when with concrete trigger phrases'; the level below would require a weaker or less specific 'when'.

Trigger Term Quality

Trigger phrasing covers several natural user formulations ('the daily inspiration references, a five-item UI prompt pack, or a dated `*-ui-inspiration-capture` article into distinct HTML landing pages'), including the dated folder pattern. It sits between anchor 4 and 5: good coverage with synonyms and a file-pattern cue, but a few natural variants (e.g., 'inspiration pack', 'build sites from today's capture') are absent, so the comprehensive-coverage anchor is not fully met.

Distinctiveness Conflict Risk

The niche is unmistakable — a completed daily UI inspiration capture with a five-item manifest, a dated `*-ui-inspiration-capture` article pattern, and Sites/Codex-task orchestration — so it is unlikely to fire for any other skill. This is a clear fit for 'Clear niche with distinct triggers; minimal conflict risk', not the level below where 'minor overlap risk with closely related skills' exists.
