Orchestrate Multi-Agent Workflows with New Path-Based Addressing and Context

Briefing for: Engineering
What happened
Codex version 0.117.0 introduces Multi-Agent v2, which replaces UUIDs with readable path-based addresses like `/root/agent_a` for structured messaging. The update also enables the app-server-backed TUI by default, adding features like filesystem watching, shell commands, and prompt history recall across sessions.
Why it matters
The retirement of legacy `read_file` and `grep_files` handlers requires engineers to migrate to the newer tool-calling surface immediately. Improved sandboxing for Windows and Linux ensures safer execution of generated code, while new websocket auth supports more complex remote development environments.
What this enables
- If you manage hierarchical agent swarms, the path-based system allows for more intuitive routing and debugging of inter-agent messages.
- If you build automation scripts, the new filesystem watch RPCs enable Codex to respond to local file changes in real-time.
- If you use parallel terminal sessions, the `/title` picker lets you label windows to keep track of different project contexts.
