Fuigo — AI skill for Claude Code

Fuigo is a general-purpose, multi-provider AI agent engine. It gives models the machinery to work: tools, persistent sessions, permission controls, workspace memory, and other agents to collaborate with. Use it to research and analyze information, create documents and code, produce structured outputs, or coordinate work across connected systems.

The Rust runtime handles execution, context, and collaboration. Its built-in tools work with files, search, and terminal commands; MCP servers and other configured tools extend what it can do in external services. Run it directly in a terminal, call it from a script, or put an application in front of it through ACP.

Choose your model and authentication route: direct OpenAI and Anthropic API keys, Flux Router and compatible gateways, local OpenAI-compatible servers, or ChatGPT and Grok subscriptions. Switch models while keeping the conversation and tool history.

Model route	Connection
OpenAI directly	Your API key with Chat Completions or Responses
Anthropic directly	Your API key with the Messages API
Flux Router and compatible gateways	A gateway endpoint, supported API protocol, and its credentials
Local models	An OpenAI-compatible endpoint, such as Ollama
ChatGPT and Grok subscriptions	Explicit provider login and a model your subscription grants access to
