Agent Zero Development

Use this skill to develop Agent Zero or operate an existing instance on the user's behalf. For projects, chats, tasks, and other application features, read references/operate-agent-zero.md and use existing APIs. Load only the references needed for the task; verify current source before changing code.

Reality Rules

1. Source and nearest DOX beat memory, examples, and this skill if they disagree.
2. Before editing, read the applicable AGENTS.md chain from the repo root to every file you expect to touch.
3. New capabilities should usually be plugins. For plugin-specific work, load a0-create-plugin for authoring/review/contribution or a0-manage-plugin for discovery and lifecycle operations.
4. Do not assume ports. Discover WebUI host/port from startup output, launcher or Docker mapping, or explicit --host, --port, WEB_UI_HOST, and WEB_UI_PORT configuration.
5. In Docker, framework checks belong to /opt/venv-a0 and agent/user code execution belongs to /opt/venv. Do not use one runtime as proof for the other.
6. Treat /a0/ as the runtime framework root inside Docker. In local development it means the repository root. If a live container matters, prove that /a0 matches the checkout before trusting source-only conclusions.
7. Do not document or change ignored usr/ or tmp/ runtime state unless the user explicitly asks.
