What problem does it solve? Bumping VS Code's bundled Codex SDK is error-prone: the public npm latest version is often unavailable in the private Azure DevOps feed used by CI, multiple version pins must stay in sync, and generated protocol clients must be regenerated and validated. This Skill automates that entire workflow safely. ## Core Features & Use Cases - Private feed version selection: Queries the private VS Code npm feed via Azure CLI authentication to find the newest stable Codex release with all platform binaries present. - Synchronized version pinning: Updates package.json, lockfiles, and codex-version.txt to the exact same version while keeping lockfile URLs on the public registry. - Protocol regeneration and validation: Regenerates the vendored app-server client, runs compile, unit, hygiene, and Agent Host E2E tests. - Real session verification: Launches an isolated Agents window and confirms a live Codex session reports the expected version sentinel. - Use Case: A maintainer needs to bump @openai/codex from 0.148.0 to the newest CI-available release; the Skill selects the version, updates every pin, regenerates the protocol client, runs all tests, and verifies a real Codex Agent Host session before delivery. ## Quick Start Use the update-codex-sdk skill to update VS Code to the newest private-feed-available Codex SDK and verify it end to end.
