Features
GBH connects desktop conversations, agent execution, and a file workspace. The default local build uses your model endpoint and runs the Host and Linux sandbox through Docker.
Tasks and working files
Agents can read and write files, run Linux commands, inspect the display, and feed tool results back to the model.
Mount a project at /workspace and open the resulting files directly on your computer.
The desktop retains conversations, execution events, and replies for ongoing work with a Bot.

Models and integrations
- Responses API: configurable URL, model, key, context budget, and timeout, with streaming tool calls.
- MCP: stdio / HTTP / SSE connections, workspace and inline configurations, scoped clients.
- Plugins and Skills: local import, installation, updates, and removal of reusable capabilities.
- Starter marketplace and Bot recipes: pinned GBH-curated Chrome and Firecrawl starters plus strict local recipe JSON import; see the operator guide for setup and verification limits.
- Web tools: WebFetch content extraction and a local SearXNG search service.

Desktop and speech
The retained desktop interface supports a local workspace, a custom icon, and macOS .app packaging.
Dictation uses CPU Whisper; Bot voice previews use Kokoro. After caching their models, speech inference runs locally.
Audio does not need to be sent to the model provider; submitting recognized text still invokes your configured model API.

| Status | Capabilities |
|---|---|
| Current-version integration coverage | Desktop → real model → sandbox → persisted reply; file operations and screenshots; MCP/plugins; English/Chinese dictation and voice previews |
| Adapter and contract coverage | Responses, Auto-review, WebFetch, WebSearch, speech interfaces, scope isolation |
| Retained implementations needing broader validation | Full calls, physical microphones/speakers, Mac execution and GUI, file transfer, attachments, recording workflows |
| Still need local adapters | Image/avatar generation, local Messages integration, additional TTS languages |
| Disabled in the local profile | Vendor login, billing, cloud provisioning, remote sync |
The verified desktop platform is Intel macOS. Image generation and full voice calls are not listed as completed features.
Building original does not establish that vendor services work. See Verification for evidence and limits.
