Use when the user wants words written or rewritten in a human, personal voice, including short casual messages: a Slack note, newsletter intro, cover letter, email, post, bio, speech or story, with or without a pasted voice sample. Also use when a draft sounds fake, robotic, generic, corporate or "ChatGPT-ish", even if they wrote it with an AI, and as a final pass on anything Claude drafted that the user will send or publish as themselves. Skip code, data, translation, proofreading-only requests, legal text, and anything whose exact wording must stay unchanged.
1 skill
Use when the user asks Claude to find, pick, compare or recommend a product to buy (for example 'find me the best toothbrush', 'which laptop should I get', 'best budget vacuum', 'X vs Y, which one?', 'what's worth buying for ...').

Use when the user wants to pick the cheapest model that still works for a custom subagent, asks whether Haiku or Sonnet would do, or wants to re-check an agent's model after new models ship (for example 'which model should this agent use?', 'could this run on Haiku?', 'bake-off my reviewer agent').
1 skill
Use when the user has a tagged PDF whose tables fail accessibility checks or read badly in a screen reader (for example 'fix the table headers in this PDF', 'my PDF tables fail PDF/UA', 'repair the table tags').
1 skill
Use when the user names a platform or medium (Roblox, YouTube, Instagram, TikTok, Twitch, Etsy, Substack and the like) and wants business ideas built on or around it, or asks what to make, sell or build there (for example 'business ideas for Roblox', 'what could I build around YouTube creators', 'find me a niche on Instagram').
