Compatibility Matrix
All embedded skills work with any LLM provider that supports tool calling. Provider-specific requirements are limited to API keys for external services.

Notes
- Binary dependencies are checked at runtime. Missing binaries produce clear error messages with installation instructions.
- Environment variables are resolved from the secret provider chain: agent-local encrypted file → global encrypted file → environment variables.
- Egress domains declared by skills are automatically merged into
forge.yaml when added via forge skills add.
- Ollama requires models with tool-calling support (e.g.,
llama3.1, mistral). Older models without tool support will not work with script-backed skills.
