From the repository
A tool calling chat bot built with Jev and no LLM.
How builders describe it
A chat-shaped command bar where Jev picks the tool, arguments, confirmation, and reply type each turn, and code calls the MCP servers, so no LLM ever writes the reply text.
The decision Jev makes
Pick an agent, a model, a skill from a catalog, or a function and its arguments.
Where it fits
Deciding which agent, model, skill or function should handle a request. Jev is a natural router: the options are fixed and the confidence tells you when to fall back. All 172 routing & model choice projects →
