# Olly HTTP Server Phase 1 Complete — Web API Ready

## Summary

Phase 1 of the Olly HTTP Server is complete. The local coding assistant now exposes a REST API and WebSocket endpoint, enabling web-based chat interfaces to connect to the same agent runtime that powers the terminal UI.

## What Was Delivered

### REST Endpoints

| Endpoint            | Method | Purpose                    |
| ------------------- | ------ | -------------------------- |
| `/health`           | GET    | Health check + agent state |
| `/api/state`        | GET    | Current agent state        |
| `/api/chat/history` | GET    | Message history array      |
| `/api/chat`         | POST   | Submit message (202 async) |
| `/api/chat`         | DELETE | Reset conversation         |

### Real-Time Features

* WebSocket endpoint at `/ws` for event streaming
* Events: `state_change`, `message`, `tool_call`, `tool_result`, `done`, `error`
* Hub-and-spoke pattern broadcasts to all connected clients
* Async processing: POST returns 202 immediately, agent runs in background

### Technical Stack

* **Go**: Fiber v2 for HTTP, fasthttp/websocket for WebSocket
* **Agent**: Typed integration with existing runtime
* **CORS**: Configurable origins with credential support
* **Graceful**: Proper shutdown handling

## Business Impact

### Enables Phase 2

Phase 1 unblocks the Web Chat UI (Phase 2). The API contract is now defined:

* Web developers can integrate immediately
* Frontend can be built in parallel with backend
* WebSocket protocol enables real-time streaming responses

### Local-First Value

Unlike cloud-based coding assistants, Olly keeps all data local:

* No API calls to external services
* Model runs locally via llama-cpp-python
* Privacy-first for sensitive codebases
* Works offline

### Developer Velocity

* Single agent, multiple interfaces (TUI + Web)
* Shared tool registry and policy engine
* Unified trace store for both interfaces

## What's Next

### Phase 2: Web Chat UI

* Next.js frontend connecting to `/api/chat` + `/ws`
* Message history persistence
* Real-time token streaming

### Future Enhancements

* Authentication for multi-user support
* Rate limiting
* Metrics endpoint for monitoring
