Codex CLI 0.146.0: named/pinned sessions, Agent Plugins, thread forking
OpenAI
OpenAI shipped Codex CLI 0.146.0, adding named and pinnable sessions via /new or /clear, Agent Plugins manifests with workspace plugin publishing and new marketplaces (Amazon Bedrock, Claude Code), thread forking with paginated history, WebSocket connections from app-server to remote Code Mode hosts, standalone web search for compatible custom model providers, and discovery of executor-provided skills. The release also bundles a batch of proxy-configuration and MCP-reconnection bug fixes.
Why it matters
Session naming/pinning and forking make Codex CLI more usable for parallel multi-thread workflows, and the new Agent Plugins marketplace integration with Claude Code signals growing cross-ecosystem plugin compatibility between competing coding agents.
