The body is lean — numbered steps with copy-paste shell commands, a compact comparison table, and a short Gotchas list — and assumes Claude's competence without explaining what whisper, BlackHole, or cargo are.

Provides fully executable commands (cargo build --release, minutes setup --model <chosen-model>, brew install blackhole-2ch, minutes record) and concrete numbered procedural steps for audio setup, with the one placeholder justified by the preceding table.

Steps 1-7 are clearly sequenced with explicit validation checkpoints: 'Skip any steps that already pass', a verify-run in step 6 to 'confirm everything passes', and a test-recording step that checks the output file exists.

This is a self-contained single SKILL.md with no own bundle and well-organized sections, satisfying the under-50-lines/no-external-references allowance for a 3; its one inline reference to a sibling skill's audio-devices.md is one level deep and clearly signaled.

Names the domain (Minutes first-time setup) and three concrete actions — 'download whisper model, create directories, configure audio input' — matching the 'lists multiple specific concrete actions' anchor.

Explicitly answers 'what' (guided first-time setup, with the three actions) and 'when' via a clear 'Use when the user says...' clause, satisfying the both-what-and-when anchor.

Covers natural user phrasings ('set up minutes', 'install minutes', 'first time setup', 'configure minutes', 'get started with minutes', 'how do I start using minutes') plus a verify-state trigger, giving good coverage of terms users would actually say.

Tied to a specific product name and distinctive setup triggers, with the 'when verify shows missing components' clause linking it to a sibling verify skill, making it unlikely to trigger for the wrong skill.
