Announce important things out loud via the `voice` CLI so the user doesn't have to keep watching the terminal. Use whenever a long-running task (deployment, build, large refactor, research run, anything that takes more than a couple of minutes) is finishing, whenever an error or blocker needs the user's attention, and whenever the next move requires user action (a decision, a credential, a manual step). Trigger even if the user didn't ask — the whole point is they're doing something else. Skip only if the work is fast enough that they're obviously still watching.

Check writing against the high-density prose tradition of Paul Graham, Naval Ravikant, Francis Bacon, and George Orwell. Use whenever the user shares an essay, post, tweet, blog draft, memo, landing page copy, or any piece of their own prose and asks for a check, edit, review, critique, or feedback on style; when they say things like "is this too wordy", "make this sharper", "tighten this", "does this sound like fluff", "rewrite in PG style"; or when they paste a paragraph and ask what's wrong with it. Also use when they ask to learn the underlying principles of clear writing or want to understand why a piece works or doesn't. The skill diagnoses thinking failures behind weak prose, not just surface errors.
