What is PROXY_MODE in Claude Code?

PROXY_MODE is a directive used at the start of a prompt that tells a Claude agent to delegate its current task to an external AI model via the claudish tool.

Can I check if a specific agent supports proxy mode?

Yes, you can run a grep command in the terminal to look for 'proxy_mode_support' within the agent's markdown file in the plugins directory.

Which agents support the PROXY_MODE directive?

Currently, 18 agents across the agentdev, frontend, and seo plugins support PROXY_MODE, including reviewers, architects, and developers. General-purpose agents typically do not support this feature.

Why did my agent respond as Claude instead of the external model?

This usually happens if you use an agent that doesn't have proxy support (like general-purpose) or if the PROXY_MODE directive was not the very first line of your prompt.

How do I format a proxy request correctly?

The directive must be the first line: 'PROXY_MODE: {model_id}' followed by a blank line and then your actual task. For example: 'PROXY_MODE: x-ai/grok-code-fast-1'.
