Routes Claude Code through a local LiteLLM proxy to hit GitHub Copilot instead of Anthropic's API, cutting direct spend while keeping your existing workflow. Generates the config.yaml with proper github_copilot provider routing, sets up ANTHROPIC_BASE_URL overrides, and walks through GitHub's device auth flow when LiteLLM first connects. Handles the common gotchas like model name mismatches between your ANTHROPIC_MODEL env var and LiteLLM's model_name, plus debugging when requests never reach the proxy or Copilot throws 401s. It's a technical workaround that works but isn't officially blessed by GitHub.
