One env var, one builder, one send(). The builder checks ANTHROPICAPIKEY, then OPENAIAPIKEY, GROQAPIKEY, GEMINIAPIKEY, MISTRALAPIKEY, DEEPSEEKAPIKEY, OLLAMAHOST, in that order, and uses whichever it finds first. No YAML, no agent framework to learn, no vendor lock-in. The agent decides which tools to call and in what order, running a ReAct loop (reason, act, observe, repeat) until it has an answer or hits the iteration cap. This works identically whether the tools touch your shell, your database, your HTTP APIs, or your codebase.
