Agent Zero Configuration

Main configuration lives in usr/settings.json and the Settings Web UI.

LLM roles:

• chat_llm: primary reasoning and tool use
• utility_llm: summaries, memory queries, compression, filtering
• embedding_llm: vector embeddings for memory and knowledge

Profiles live in agents/<profile>/; user profiles live in usr/agents/<profile>/. Profiles override prompt fragments without changing the framework.

Plugins live in plugins/ and usr/plugins/. Each plugin has a plugin.yaml; activation can be global or scoped to projects/profiles.

Projects isolate workdir, memory/knowledge scope, custom instructions, secrets, MCP config, and repositories.

Environment settings can use A0_SET_<setting_name>=<value>.
