Reference

Technical lookup tables and protocol details.

Environment variables

Every configuration key the app reads, where it’s read from (.env vs the in-app encrypted store), whether it’s required or optional, and what it does. If you’re wondering what to put in your .env or what a setting in the UI maps to in code, this is the page.

HTTP endpoints

The REST API surface: session reset, configuration, logs, notes, MCP management, and the install/auth endpoints. Useful if you’re scripting against the server or building an integration.

WebSocket endpoints

Protocol details for the three WebSocket connections: /chat (text), /call (Twilio phone, G.711 µ-law audio), and /browser-call (browser voice, PCM16 24 kHz). Covers message shapes, connection lifecycle, and audio format specs.

Model calling flows

Sequence diagrams showing the exact chain of API calls for each type of turn: a simple text message, a web_search tool call, a voice barge-in, and a phone call. Useful when you need to understand latency, token usage, or where something in the pipeline is failing.

Architecture

The single-session singleton design, the single base agent, the tool registry, and the WebSocket routing. The right page to read before making significant changes to the codebase.
