Outcome

The framework now supports adding new LLM providers with minimal effort, eliminating code duplication and simplifying configuration.

Workflow

• Add a row to PROVIDER_PROFILES with key_envs, detect_envs, base_url_envs, base_url, model, url_markers
• Extend the SUPPORTED_PROVIDERS Literal to include the new provider name
• Add the provider’s environment variable description to .env.example
