What environment variables are required for this skill?

You must set an OPENROUTER_API_KEY. It is also recommended to set ANTHROPIC_API_KEY to a placeholder and CLAUDISH_MODEL to your preferred default model.

Why is it critical to run Claudish through sub-agents?

Running Claudish in the main context can inject over 10,000 tokens of reasoning and conversation history into your window. Sub-agents isolate this data, keeping your main session clean and efficient.

Which models are best for programming tasks via Claudish?

Currently, x-ai/grok-code-fast-1 is recommended for speed and agentic coding, while google/gemini-2.5-flash and openai/gpt-5 are preferred for complex reasoning and architecture.

What is Claudish and how does it work with Claude Code?

Claudish is a CLI tool that acts as a proxy, allowing Claude Code to communicate with any model hosted on OpenRouter. It mimics the Anthropic API to provide compatibility with alternative models like Grok and Gemini.

Developer Tools

Enables Claude Code to utilize OpenRouter models through delegated sub-agents to optimize context window efficiency.

This skill provides a specialized framework for integrating the Claudish CLI with Claude Code, allowing developers to leverage alternative models like Grok, GPT-5, and Gemini while strictly maintaining context window hygiene. It includes a mandatory decision tree for agent delegation, specialized file-based instruction patterns, and a curated selection matrix to ensure that external model calls happen within isolated sub-agents. By following these patterns, users can prevent token pollution in their main conversation while harnessing the specialized capabilities of various state-of-the-art language models.
