Privacy-first · workspace stays local

Speak. Think. Ship.

Voice-controlled ReAct agent for VS Code. The engine reasons. The extension executes file, grep, and terminal tools on your machine — with Keep / Undo and HITL for shell.

Local tools

read, write, edit, grep, listdir, run_command. Paths clamped to workspace root.

Streaming UX

SSE tokens + tool_request events. Chat never waits for the full loop.

Secrets

Engine token and LLM keys in OS keychain via SecretStorage. Never settings.json.

Add error handling to signIn and cover it with tests

Reading src/auth.ts, src/session.ts. I’ll keep the session contract, throw typed errors, and add three tests.

tool read auth.ts
tool grep signIn
tool edit auth.ts, auth.test.ts
HITL npm test — waiting for you

Local or cloud engine

Tools always execute in the extension. Only bounded context leaves the machine.

Local mode (default)

Extension + FastAPI :8000 + speech :3001. Engine reads the workspace directly.

Cloud mode (Render)

POST /v1/generate/stream → SSE token + tool_request → local execute → tool_result.
