Three lean lines assume Claude's competence — no explaining what TTS is or how libraries work — and every token earns its place, matching the lean-and-efficient anchor rather than the padded score 2.

Provides a concrete, executable command 'gen_vo.py --text "..." --voice <id> --out vo.mp3' with all flags and the output file, plus the data-source note; the placeholders are appropriate since the recipe supplies them, so it is not incomplete like the score 2 pseudocode anchor.

A simple single-action skill whose one action (run gen_vo.py with text/voice/out) is unambiguous; per the simple-skills note this can score 3 without a multi-step sequence, and no destructive/batch validation is needed.

The body references gen_vo.py and media_proxy, which are real files in scripts/, with one-level-deep pointers and no nesting; for an under-50-line simple skill, well-organized sections suffice for a 3 per the scoring notes.

Lists multiple concrete actions — 'Generate a voiceover (VO) clip via ElevenLabs text-to-speech, ROUTED THROUGH THE elevenlabs-proxy', sourcing 'Voice id + script text come from the template recipe' — matching the multi-action anchor rather than the single-domain score 2.

Explicitly answers both what ('Generate a voiceover... via ElevenLabs text-to-speech') and when ('Use for the spoken narration of VO-driven video-ad formats'), with an explicit 'Use for' trigger clause, so it is not capped at 2 for a missing trigger.

Covers natural terms a user would say — 'voiceover (VO)', 'ElevenLabs text-to-speech', 'spoken narration' — alongside the concrete ad-format triggers, giving good coverage rather than the partial score 2.

Narrow niche (ElevenLabs VO for specific video-ad formats via a mandatory proxy) with distinct triggers makes it unlikely to fire for unrelated skills, matching the clear-niche anchor.
