 Codex receives Caveman through its native plugin adapter. Humanizer, Impeccable, and Anthropic Frontend Design are downloaded as skill payloads from the GitHub sources in the manifest, without running upstream installers. All three appear in the extension selector for Codex. Ownership is recorded in `~/.my-ai-configuration/extensions.json`. Skill files are tracked by hash; modified or foreign files are retained with a warning. Existing installations from before ownership tracking are not automatically adopted.
 
+On Windows, installation and update repair the known Caveman 1.0.0 hook launcher in setup-owned Codex installations so it resolves the plugin path under PowerShell as well as Command Prompt. Custom commands and foreign installations are preserved. Review the changed hook definitions in Codex `/hooks`; setup does not grant hook trust automatically.

 [QMD](https://github.com/tobi/qmd) requires Node.js 22 or newer and `npm`. Selecting it installs `@tobilu/qmd` globally. Claude receives QMD's official `qmd@qmd` plugin; Codex registers `qmd mcp` as its MCP server. Deselecting QMD removes the client integration owned by this setup, but leaves the global `qmd` executable installed.
 
 Normal installation and update also ask whether to update the selected client CLIs, enable Flashbang, and enable the optional Qwen3-Embedding-0.6B semantic retrieval layer. Retrieval uses a per-user virtual environment and index and is invoked through the installed `server.py search` CLI, disabled by default. Quickupdate reuses the saved shell, client, CLI update, Flashbang, retrieval, and extension choices without opening menus. Disabling retrieval removes its setup-owned runtime and index. Only successful runs save selections; dry runs do not update CLIs, extensions, or retrieval.
