The operators have different trust and execution roles. They are not interchangeable bots with one giant token and a shared shell. | Component | Responsibility | Canonical guide | | --- | --- | --- | | GPTomek | GitHub App identity for bot-authored commits, comments, patches, reactions, and guarded branch changes | [GPTomek](https://github.com/trvny/trvny/blob/main/gh-apps/gptomek/README.md) | | Kanarek Companion | PR coordination, events, and shared Worker operator plumbing | [Companion](https://github.com/trvny/trvny/blob/main/gh-apps/kanarek-companion/README.md) | | Kanarek Review | Model/provider routing for automated review work | [Review](https://github.com/trvny/trvny/blob/main/gh-apps/kanarek-review/README.md) | | Pet Dispatcher | Workspace-confined MCP development-machine tools and an outbound-only remote control plane | [Dispatcher](https://github.com/trvny/trvny/blob/main/mcp/pet-dispatcher/README.md) | ## Key boundaries **GPTomek** authors protected GitHub mutations; pull requests are normally opened by `trvny` so external reviews trigger. It is not a remote shell. **Pet Dispatcher** runs scoped workspace sessions, bounded filesystem/Git operations, and process-confined execution on an authorized machine. Its Cloudflare Queues transport does not broaden the local permission boundary. **Kanarek Review** and the Companion have separate responsibilities; their model routing, quip storage, and PR handling should not be inferred from the Android Kanarek news app. Inspect current main-branch instructions and security docs before changing an operator.
