Left of the Loop: The Trireme
Short summary
Solo developers with AI agents can ship fast but often solve the wrong problem because no one challenges their assumptions. A functional team needs three irreplaceable functions: someone framing what's worth building, someone challenging that framing, and someone representing user or business needs. The agent is a fourth seat implementing what the three produce.
- •Solo + agent creates circular validation: agent agrees with your prompt, your prompt reflects your blind spots
- •Minimum team requires three functions: problem discovery, framing challenge, user/business representation
- •Agent is the fourth seat implementing decisions, not replacing any of the three
Generated with AI, which can make mistakes.
Is this a good recommendation for you?
