## Why Included

HarnessAgent can now pass images to vision models through every supported coding-agent adapter, so image-based tasks can use the same AI SDK message flow as text.

## Source Summary

HarnessAgent accepts images in the standard AI SDK message format, using a content array with **text** and **file** parts. The feature works across **all available adapters**, including Claude Code, Codex, Cursor, and OpenCode.

## Practical Implication

Builders can include screenshots or other image files in agent requests without changing the message format between harnesses. The image is handled by the adapter’s underlying vision model.

## Agent-Ready Context

HarnessAgent accepts images in the standard AI SDK message format, using a content array with **text** and **file** parts. The feature works across **all available adapters**, including Claude Code, Codex, Cursor, and OpenCode.

Builders can include screenshots or other image files in agent requests without changing the message format between harnesses. The image is handled by the adapter’s underlying vision model.

Image understanding still depends on the underlying model. The announcement does not specify supported image formats or size limits.

## Connected Context

Feed7 judgment across 944 accumulated Signals:

This makes image input part of HarnessAgent’s common message format across its available adapters, so builders can send screenshots or other images without changing formats when switching harnesses. Image understanding still depends on the underlying vision model, and the source leaves supported formats and size limits unspecified.

No material corpus connection was strong enough to record.

## Context Map

- Layer: tools
- Domains: coding, image
- Topics: agent-sdks, tool-use

## Uncertainty

- Image understanding still depends on the underlying model. The announcement does not specify supported image formats or size limits.
