[dependabot]

Bumps @openai/agents from 0.3.8 to 0.4.0.

Release notes

Sourced from @​openai/agents's releases.

v0.4.0

Key Changes

Drop Zod v3 support and require Zod v4 for schema-based tools and outputs

Starting with this version, we have dropped support for Zod v3 and now require Zod v4 for schema-based tools and outputs. Please use zod@4 instead of zod@3. If you use this SDK in vanilla JavaScript and do not rely on the TypeScript compiler, the SDK will still work with the Zod v3 runtime.

Make @​ai-sdk/provider an optional peer dependency to support v2 and v3 formats

The @ai-sdk/provider dependency was previously a required dependency of the openai/agents-extensions package, but it is now an optional peer dependency. This breaking change is primarily intended to support both v2 and v3 formats. In addition, changing how the dependency is loaded allows developers to use the latest major version without waiting for this SDK to migrate.

Update gpt-5.1/5.2 defaults and reasoning effort types

This change is more minor than the two above. We updated the default reasoning effort for gpt-5.1 and gpt-5.2 to "none". When you use gpt-5.1 or gpt-5.2, the default reasoning effort is now "none", which is better suited for interactive agent apps. If you intentionally relied on "low" effort (the default in v0.3), please explicitly pass your own ModelSettings with reasoning.effort="low".

Experimental: Codex Tool Support

Starting with this version, we have added a new experimental Codex extension (@openai/agents-extensions/experimental/codex). This extension allows you to use Codex as a tool within your agents. Since this module is still experimental, its behavior and implementation details may change in future releases.

If you run an agent with codexTool() on a host where Codex is installed, the agent will use Codex as a tool to answer the question. The tool simply runs the Codex CLI as a subprocess, so all existing Codex configuration, skills, and capabilities are available without any additional setup.

See the example code and openai/openai-agents-js#862 for more details.
