Use when writing, recording, updating, or troubleshooting the agent host end-to-end tests under src/vs/platform/agentHost/test/node/protocol (black-box tests that drive the whole agent host over the AHP protocol, using a CapiReplayProxy record/replay system for Claude/Copilot/Codex). Covers adding a cross-provider test, re-recording fixtures after an SDK bump, gating non-deterministic or platform-specific tests, and diagnosing replay cache misses.

Agents window architecture — covers the agents-first app, layering, folder structure, chat widget, menus, contributions, entry points, and development guidelines. Use when implementing features or fixing issues in the Agents window.

Set up and automate VRChat avatar modding workspaces in Unity. Use when Codex needs to install or verify the VRChat-compatible Unity/VCC/VPM environment, import arbitrary avatar and clothing packages, attach adapted clothing to an avatar, merge armatures/bones with Modular Avatar or NDMF, preserve and combine FX controllers, expression menus, and parameters, localize menu labels, validate synced parameter cost, debug clothing/tail/body toggles, preview with Gesture Manager, prepare private SDK upload builds, or produce a reusable VRChat-ready scene/prefab for any avatar plus any compatible outfit.
