GitHub Agentic Workflows v0.75.4: Hardened Codex Engine with Permission-Mode Auditing and OTel Trace Inheritance

GitHub·medium signal

Released May 26, the latest GitHub Agentic Workflows update defaults to gpt-5.3-codex as the Codex engine, adds explicit permission-mode auditing for agent actions, improves OpenTelemetry trace inheritance for end-to-end observability across agent chains, and fixes Gemini stream parsing. Focus areas are stability, security boundaries, and observability for coding agents running in CI/CD pipelines. For teams running coding agents in Actions, the permission-mode auditing gives much-needed visibility into what agents are actually doing.
