Short summary
Most AI demos stop when something appears on screen. This one starts there.
Dalton Anderson uses OpenAI Codex to turn fictional customer feedback into a working dashboard, then critiques the first output, steers the redesign, and explains the system around reliable agent work: Plan as the map, Goal as the contract, skills as reusable procedures, and evaluations plus stop conditions for agentic loops.
A practical episode for founders, operators, and builders who want better results from Codex without giving up judgment.
### Mobile-first show notes
Most AI demos stop when something appears on screen. This one starts there.
Dalton gives Codex a fictional customer-feedback dataset and asks for a decision-ready dashboard. The first output works, but it is not good enough. That becomes the real lesson.
This episode shows how to move from a one-shot prompt to a workflow you can inspect, steer, and verify.
You will learn:
- Why Plan is the map and Goal is the contract
- The four parts of a strong goal: outcome, context, constraints, and done-when evidence
- When a repeatable workflow should become a skill
- How clear names keep a growing skill library usable
- Why every agentic loop needs an evaluation and a hard stop
- Where human judgment still matters
The demonstration uses fictional data. No outreach is sent.

Install selectively. Read a skill before trusting it, understand the tools and permissions it can use, and test it on bounded work first.
