Conciseness

The body is lean and dense with skill-specific knowledge: exact commands, a full config field table, pacing numbers ('~1.6–2.8 s per line... about 18 characters a second'), refusal rules, known gaps, and a QC checklist. It never explains concepts Claude already knows (Playwright, ffmpeg, and Apple Notes are named, not taught), matching anchor 5 ('Lean and efficient; assumes Claude's competence; every token earns its place').

Actionability

The Run block is fully executable and copy-paste ready ('cd scripts && npm install', 'npx playwright install chromium', the three node/bash invocations with flags and expected outputs), the Config section documents every field with a pointer to a real scripts/config.example.json that matches the documented schema, and all referenced bundle files (record-notes.js, render-end-card.js, stitch.sh, scripts/mockup/) exist. This matches anchor 5 ('Fully executable; copy-paste ready code or commands; specific examples cover the common cases').

Workflow Clarity

The sequence is clearly ordered (install once → free --still-only review stills → record notes → render end card → stitch master) with real checkpoints: review stills before committing to video, built-in script validation (record-notes.js refuses em/en dashes or >80-char lines; render-end-card.js refuses missing rows/logo and fails on unloaded fonts), and an explicit Self-QC checklist. It falls short of anchor 5 because there is no fix-and-retry feedback loop when a QC check or script refusal fires — the Self-QC section says what to watch for but not what to correct and re-run.

Progressive Disclosure

SKILL.md is a genuine overview: implementation is appropriately split into the scripts bundle (record-notes.js, render-end-card.js, stitch.sh, mockup/generate.js), and the config detail is clearly delegated one level deep to 'scripts/config.example.json' (verified to exist and consistent with the documented blocks). No nested references, no inlined content that belongs elsewhere, easy navigation — matching anchor 5.

Specificity

The description lists multiple concrete, comprehensive actions: 'Assemble an Apple Notes list video ad', 'a frame-accurate fake iPhone screen recording of a short list being typed into Apple Notes (character by character, key pops, blinking caret, the note scrolling up as it fills) crossfaded into a checklist end card', plus 'an optional music bed' and the toolchain '(Playwright + ffmpeg)'. Every capability of the skill is explicitly stated with no vague filler; this matches the anchor 'Lists multiple specific concrete actions; comprehensive coverage' and sits clearly above the 'minor gaps in coverage' level 4.

Completeness

Both are present: 'what' is fully and concretely answered, and 'when' is explicit ('Use for the apple-notes format'), so this is above anchor 3 where 'when' is missing or only weakly implied. But the 'when' clause is thin — it names an internal format token rather than concrete user-facing trigger phrases like 'when the user mentions X', which is what anchor 5 requires.

Trigger Term Quality

Good natural keyword coverage: 'Apple Notes', 'iPhone screen recording', 'video ad', 'checklist', 'list', 'end card', 'music bed'. However the explicit trigger clause 'Use for the apple-notes format' leans on the internal format name rather than phrases a user would naturally say (e.g. 'fake notes typing video', 'typed-list ad'), so a few natural synonyms are missing — matching anchor 4 ('Good keyword coverage; a few natural terms missing'), not the comprehensive synonym/extension coverage of anchor 5.

Distinctiveness Conflict Risk

The description carves out a clear niche and explicitly disambiguates it: 'The Apple Notes sibling of render-imessage-chat and render-chatgpt-chat' plus the distinctive Apple Notes typing-recording framing. This matches anchor 5 ('Clear niche with distinct triggers; minimal conflict risk'); the named siblings reduce rather than raise overlap risk.
