OpenAI Codex release notes: 0.150 links agent tasks with @

OpenAI Codex CLI 0.150.0 can now reference other Codex tasks with @ directly in the terminal interface. The selected task is attached as a live reference, so the agent can read it before answering.

Codex CLI is OpenAI's coding agent for the terminal. TUI means terminal user interface, the interactive view where you work with Codex.

OpenAI Codex release notes: @ loads another task

When the active thread supports task tools, the @ popup includes matching Codex tasks and prioritizes tasks from the current working directory. Selecting a task submits it as a bounded live thread reference. Codex then reads its contents with read_thread instead of treating the task title as the full context.

The release also gives Codex tools to list, read, wait on, create, fork, rename, archive, restore, and message tasks. Delegation tools run through a local MCP server with explicit approvals and respect configured MCP policies. Older app servers without this support start threads without the dynamic tools.

Human step: select the task in Codex

1. Use the Codex TUI in version 0.150 or later.
2. Type @ in the composer and select the intended task from the popup.
3. Keep the reference in the message, then add what the agent should compare or retrieve.

Short example: use the new Codex feature

Select the task through @, then send this to the agent:

Read @TASK before answering. Compare its current decisions and changed files with this task. List shared dependencies, conflicts, and the next handoff. Do not change either task.

Good output should:

• Show that the referenced task was read.
• Name shared files or dependencies when they exist.
• Separate conflicts from the next handoff.
• Stop without changing either task.

The current stable version is 0.150.1

OpenAI published 0.150.0 on August 26. Version 0.150.1 followed on August 27 and is now the npm package's latest release. The patch retains the features above and fixes remote compaction so retained images count toward the token budget, trimming older images when needed.
