 Unlike simple wrappers, Codex Mate acts as a **Local Agent Bridge**:
 - **Unified Session Browser**: Search, inspect, filter, and export local sessions across Codex, Claude Code, Gemini CLI, and CodeBuddy Code from one place.
-- **OpenAI-Compatible Bridge**: Use Codex with any OpenAI-compatible UI by normalizing the Responses API.
+- **OpenAI-Compatible Bridge**: Use Codex with any OpenAI-compatible UI by normalizing the Responses API; the built-in Codex conversion also fills and normalizes Codex fingerprint headers such as `User-Agent`, `Version`, `OpenAI-Beta`, and `Originator` so upstream providers see an official Codex CLI-shaped request.
 - **Claude Provider Bridge**: Connect Claude Code to OpenAI Chat Completions-compatible providers and Ollama through the built-in local Claude-compatible proxy.
 - **OpenCode Provider Control**: Manage OpenCode provider/model selection with a CodexMate-owned provider store under `~/.codexmate`, projecting only the active provider into native OpenCode config to avoid polluting or deleting user-owned settings.
 - **Skills Marketplace**: A local-first market to share and import skills between different agent apps.
