I used to create a skeptical VC investor persona through prompting whenever I ran ideas and actual business plans through AI. Recently, after working on a business plan for weeks, I used Claude Cowork with Opus 5/High to evaluate the same concept. Instead of prompting for critique and redesign each time, I built a Skill upfront. The concept is the same, but the Skill makes the execution much more effective. It reviews ideas or detailed business plans, researches first, and critiques only after that. It also analyzes and suggests wedges and new moats and, when instructed, generates detailed business plans. It works well as a one-shot analysis, but it is most effective when I push back and challenge it further.

I used to prompt AI to role-play a skeptical VC investor when reviewing ideas and business plans. 2. After working on a business plan for several weeks, I ran the same concept through Claude Cowork with Opus 5/High. 3. Instead of prompting separately for critique and redesign, I built a Skill upfront. 4. I designed the Skill to research first and critique only afterward. 5. I used it to review ideas or detailed business plans, analyze and suggest wedges and new moats, and generate detailed business plans when instructed. 6. I continued the analysis by pushing back and challenging the Skill beyond its initial one-shot response. 7.
