CODEX LOCKS IN CROSS-OS PATH HANDLING AS PLUGIN ROUTING HARDENS

By RepoJournal · Filed · About OpenAI · Composed from the cited sources · methodology

PathUri is moving to the exec-server core while the plugin auth stack gets tighter, setting up Codex to run faithfully across Windows, macOS, and Linux.

The PathUri migration hit two critical milestones overnight. App-server is now translating between URI-encoded paths and OS-native formats at its public API boundary [1], which means downstream consumers see clean, platform-appropriate paths without URI baggage. Simultaneously, exec-server's working directory parameter is shifting to PathUri [2], completing the second-to-last piece of protocol migration needed for genuine cross-OS operation. Both changes reject non-native URIs before execution, which prevents silent failures in heterogeneous deployments. On the testing front, the Wine harness now includes PowerShell [4], making cross-platform integration tests actually representative of what ships. The build infrastructure got smarter too: buildifier v8.5.1 is now pinned and provisioned centrally via DotSlash [5], so contributors format Bazel files consistently without installing anything locally. The plugin layer tightened as well. Codex now deduplicates plugin MCPs by app declaration name [3], meaning if a plugin declares both an App route and an MCP route for the same endpoint, ChatGPT sessions use the App route and never see the conflicting MCP. This is foundational work: each piece unblocks the next phase of plugin auth routing.
