PROXY_MODE Reference Guide

What is PROXY_MODE?

PROXY_MODE is a directive that tells an agent to delegate its task to an external AI model via Claudish.

How It Works

1. Orchestrator launches Task with PROXY_MODE-enabled agent
2. Agent detects PROXY_MODE: {model} at start of prompt
3. Agent extracts model ID and actual task
4. Agent runs claudish --model {model} with the task
5. Agent returns external model's response

Multi-Backend Routing

Claudish routes to different backends based on model ID prefix:

Prefix	Backend	Required Key	Example
(none)	OpenRouter	OPENROUTER_API_KEY	x-ai/grok-code-fast-1
or/	OpenRouter (explicit)	OPENROUTER_API_KEY	or/google/gemini-3-pro
g/ google/	Gemini Direct	GEMINI_API_KEY	g/gemini-2.0-flash
oai/ openai/	OpenAI Direct	OPENAI_API_KEY	oai/gpt-4o
ollama/	Ollama	None	ollama/llama3.2

⚠️ Prefix Collision Warning

OpenRouter model IDs like google/gemini-3-pro collide with the google/ routing prefix!

Always use or/ prefix for:

• or/google/gemini-* (OpenRouter's Google models)
• or/openai/gpt-* (OpenRouter's OpenAI models)

Safe without prefix:

• x-ai/grok-*
• anthropic/claude-*
• deepseek/*
• minimax/*
• qwen/*
• mistralai/*
• moonshotai/*

The PROXY_MODE Directive

Format:

PROXY_MODE: {model_id}

{actual task}

Example:

PROXY_MODE: x-ai/grok-code-fast-1

Common Mistakes

Mistake 1: Using general-purpose

// ❌ WRONG
Task({
  subagent_type: "general-purpose",
  prompt: "PROXY_MODE: grok..."
})

general-purpose doesn't have <proxy_mode_support> so it won't recognize the directive.

Mistake 2: Instructing agent to run claudish

// ❌ WRONG
Task({
  subagent_type: "general-purpose",
  prompt: "Run claudish with model X to review..."
})

The agent doesn't know the claudish pattern. Use PROXY_MODE instead.

Mistake 3: Wrong prompt format

// ❌ WRONG - PROXY_MODE must be first line
Task({
  subagent_type: "agentdev:reviewer",
  prompt: "Please review this plan.
PROXY_MODE: grok..."
})

The directive must be at the START of the prompt.

Correct Usage Pattern

// ✅ CORRECT
Task({
  subagent_type: "agentdev:reviewer",
  description: "Grok review",
  run_in_background: true,
  prompt: `PROXY_MODE: x-ai/grok-code-fast-1

Review the implementation at path/to/file.ts

Focus on:
1. Code quality
2. Error handling
3. Performance
4. Security`
})

Checking Agent Support

To verify if an agent supports PROXY_MODE:

# Find agents with PROXY_MODE support
grep -l "proxy_mode_support" plugins/*/agents/*.md

# Check specific agent
grep "proxy_mode_support" plugins/agentdev/agents/reviewer.md

Troubleshooting

"Agent didn't use external model"

Cause: Agent doesn't support PROXY_MODE Fix: Use a PROXY_MODE-enabled agent (see table above)

"Got Claude response instead of Grok response"

Cause: general-purpose or other non-PROXY_MODE agent was used Fix: Switch to agentdev:reviewer or similar

"PROXY_MODE directive in output"

Cause: Agent treated directive as content, not instruction Fix: Use correct agent; ensure directive is first line
