Codex adds cross-thread referencing, agent orchestration

Native cross-thread communication turns Codex into a lightweight multi-agent orchestrator directly in the workspace, bypassing the need for complex external agent frameworks.

• –Drag-and-drop and @-mentioning UX dramatically lower the barrier to managing multi-agent workflows compared to code-first orchestration libraries.
• –Inter-thread messaging and monitoring prevent context window exhaustion by distributing specialized tasks across independent, focused threads.
• –Coupling scheduled triggers with inter-thread communication enables autonomous recurring background maintenance, such as automated PR reviews and dependency updates.
• –Centralizing thread-to-thread collaboration directly inside Codex challenges standalone orchestration platforms by keeping agents close to the developer's working state.
