Episode notes
In-Browser Full-Stack Agent
- Tidewave Web runs a coding agent in the browser alongside your app, mapping UI elements to server templates for precise edits.
- This eliminates manual context-switching and reduces repetitive debugging when adding features.
Point To Elements, Don’t Describe Them
- Use the inspector to point to the exact element you want changed instead of describing it verbally to the agent.
- Let Tidewave map the HTML to server templates so the agent can produce targeted code edits.
Autoplay Demo Validated By DOM Checks
- In a demo Tidewave automated autoplay by clicking and checking DOM properties to confirm video scaling.
- José used this to show Tidewave can drive the browser and validate runtime UI changes.
