🧠 The Universal Cowork Formula
Essential

Every great Claude Cowork prompt contains these 5 components. The more you include, the better the output:

GREAT PROMPT = IDENTITY + CONTEXT + TASK + FORMAT + CONSTRAINTS IDENTITY: Who you are → "I'm a Head of Product at a B2B SaaS startup" CONTEXT: Situation & background → "We're preparing for Series A and need..." TASK: Specific request → "Write a competitive analysis framework..." FORMAT: Output structure → "...as a structured table with 8 competitor rows" CONSTRAINTS:What to include/avoid → "Focus only on our 3 direct competitors"
⚡ Quick Version

If you can only remember one thing: Always tell Claude who you are, what you're building, and who will use the output. These three facts alone improve output quality by 50%.

🔄 The 5-Step Cowork Workflow
Process
  • Brief: Define identity, context, task, format, constraints upfront. Invest 5 minutes here.
  • Structure first: Get the outline/architecture approved before any drafting begins. Saves hours of rework.
  • Draft: Generate sections. For long content — one section at a time is better quality than all at once.
  • Self-critique pass: Ask Claude "What are the 3 weaknesses in what you just wrote?" and then address them.
  • Verify & personalize: Fact-check specific claims. Add your voice, specific examples, and judgment calls.
📄 Document Analysis Quick Reference
Documents

Copy-paste starter prompts for any document type:

CONTRACT REVIEW: "Review this contract from my perspective as [ROLE]. Flag: 🔴 High-risk clauses | 🟡 Unusual terms | 🟢 Missing protections For each flag: quote + plain-English risk + suggested alternative." RESEARCH PAPER: "Summarize using IMRAD structure. Then: key finding in 1 sentence, methodology in plain English, 2 biggest limitations, 1 gap for future research." BUSINESS REPORT: "Extract the 5 most actionable insights for a [ROLE]. For each: what it means for my organization + what I should do about it." POLICY DOC: "I need to comply with this policy. Tell me: what do I need to do, by when, what constitutes non-compliance, and what's ambiguous?"
✅ Always Do
  • Tell Claude what you'll use the output for
  • Add "Based ONLY on this document" for factual work
  • Ask Claude to cite specific sections
  • Verify critical claims against the source
❌ Never Do
  • Paste personal data (names, SSNs, confidential PII)
  • Rely on Claude alone for high-stakes legal decisions
  • Upload scanned images (Claude reads text, not images)
  • Assume numerical extractions are 100% accurate
🔬 Research Assistance Quick Reference

Step 2: [Conduct real research using Google Scholar, Perplexity, databases] Step 3: "Here are my findings: [paste]. Synthesize into a structured report." Step 4: "What gaps, contradictions, and unexplored territories does this reveal?" COMPETITIVE INTEL FORMULA: "Build a competitive matrix for [MARKET]. Dimensions: [pricing / positioning / target segment / key feature / weakness] Format: table with color-coded strength ratings" LITERATURE REVIEW FORMULA: "Synthesize these papers [paste summaries].

⚠️ Remember

Claude's training data has a cutoff — don't ask it for current market data, recent news, or updated statistics. Use Perplexity AI or Google for live information, then bring findings to Claude for synthesis.

  • Accept the first draft as professionally final
  • Trust specific citations without verification
