Master AI before it masters you.
You still use Claude like in 2025. So here's a recap in a single cheat sheet: 1: Claude isn't 1 tool. It's 6. Chat, Projects, Code, Cowork, Skills, Connectors. If you don't code, Cowork should be the go-to one. 2: Pick the model before the prompt. Opus 4.7 = thinking, analyzing, planning. Sonnet 4.6 = grammar, brainstorming, formatting. Haiku 4.6 = bulk tasks at 1M input tokens. 3: Toggle Extended Thinking on Opus. Model selector → Opus 4.7 → Turn on Extended Thinking. Forces an internal monologue. 4: Cowork > Chat for serious work. Desktop + Pro only. Reads your local files. Creates docs. Runs for minutes while you grab coffee. 5: Stop writing 500-word prompts. Write 29 words: "I want to [task] so that [goal]. Read the files first. Ask me questions via AskUserQuestion before executing." 6: Build 3 folders inside Cowork. ABOUT ME/ (identity + rules). TEMPLATES/ (reusable patterns). CLAUDE OUTPUTS/ (deliverables). Your prompts drop to 10 words. 7: Set Global Instructions once. Settings → Cowork → Edit Global Instructions. Prompt: "read ABOUT ME first, save in CLAUDE OUTPUTS, use AskUserQuestion when unclear, don't over-explain." 8: Connectors are free. Turn them on. Slack, Gmail, Drive, Notion, Figma, Granola + 50 others. Claude reads your emails and messages mid-conversation. Zero copy-paste. 9: Force AskUserQuestion in every prompt. Claude stops guessing. It generates a form with clarifying questions. You click. Claude executes. Prompting ends. 10: Install Claude in Excel (3 minutes). Excel → Insert → Get Add-ins → Search "Claude by Anthropic" → Add → Sign in. Ctrl+Option+C to open. It now knows what cell D14 actually contains. 11: Install Plugins from claude .com/plugins. Sales, Marketing, Legal, Finance, Data, Product, Support + more. Each adds skills and slash commands. Type / in the chat to see them. 12: Skills replace your prompt library. Turn repeat workflows into slash commands. Type /negotiation-prep + one line. Claude pulls from Gmail, Slack, Granola. Drafts the email. Done. 13: Context > Prompts. Feed your files, not just prompts. That's the game. Download my own files at how-to-ai.guide. Don't pay anything. Reply to the email to get the link 14: Examples > Prescriptions. Paste 3 posts you wrote. "Write like this." Claude copies voice faster from examples than from 500 words of description. 15: Images = Use ChatGPT Image (with Thinking). Claude doesn't generate realistic images (yet). 16: Real-time search = Use Grok. Connected to X. Covers 99% of what you need. 17: Videos = Use Google Veo-4 Right tool, right job.
