Claude Cowork Setup and Prompt Template

Setup: 1. Open the Claude desktop app. 2. Click "Cowork" (not Chat). 3. Point it to a folder with your context files. 4. Create 3 files: about-me, my-company, anti-ai. Before prompting, change these 2 settings: 1. Turn on "Extended Thinking" - it forces Claude to think before answering. 2. Select "Opus 4.7" model - top-tier for deep, multi-step work. (Note: Opus 4.7 with Extended thinking burns tokens faster. Only use these settings for complex tasks.) Then paste this prompt: "I want to [TASK]. Read all files first. Ask me questions using AskUserQuestion before you execute. Do not guess."
