Giving Coding Agents Visual Feedback

Coding agents need evidence about the screen, not only compiler and test output.

Coding agents already consume compiler errors, test failures, and lint output. Interface work needs another signal: what the changed product actually looks like.

An agent-native visual loop should expose the flow, context, baseline, candidate, diff measurement, and review state through a stable machine-readable interface. The agent can run the flow, inspect a failed context, change the code, and publish a replacement candidate.

Keep approval separate from correction

Agents can diagnose and self-correct, but they should not silently redefine the approved baseline on protected branches. The merge check remains pending until a human accepts the visible result.

That separation produces a useful division of labor: machines iterate quickly on evidence; people decide whether the evidence is acceptable.

The result is not “AI replaces visual review.” It is a shorter path from a visual regression to a corrected candidate before scarce human attention is spent.
