feat: OpenAI-compatible HTTP server platform adapter

Salvaged from PR #956 (teknium1) onto current main.

Adds an OpenAI-compatible HTTP server as a new gateway platform
adapter. Any frontend that speaks the OpenAI format — Open WebUI,
LobeChat, LibreChat, AnythingLLM, NextChat, ChatBox, etc. — can
connect to hermes-agent by pointing at http://localhost:8642/v1.

Endpoints:
- POST /v1/chat/completions — stateless chat (full conversation per request)
- POST /v1/responses — stateful via previous_response_id or named conversations
- GET/DELETE /v1/responses/{id} — retrieve/delete stored responses
- GET /v1/models — model discovery
- GET /health — health check

Key features:
- Real SSE streaming via stream_delta_callback
- Responses API with server-side conversation state (in-memory LRU, max 100)
- Named conversations via 'conversation' parameter
- System prompt layering (frontend prompts add to core agent prompt)
- Bearer token auth (optional, via HTTP_SERVER_KEY)
- CORS support for browser-based frontends
- Binds to 127.0.0.1 by default (secure)
- Uses aiohttp (existing dependency, no new deps)

Files:
- gateway/platforms/http_server.py — adapter implementation
- gateway/config.py — Platform.HTTP_SERVER enum + env var overrides
- gateway/run.py — adapter factory branch
- toolsets.py — hermes-http_server toolset
- hermes_cli/config.py — setup env vars
- .env.example — HTTP server env vars
- tests/gateway/test_http_server.py — 72 tests
- website/docs/ — HTTP server guide, Open WebUI integration guide

Closes #956

 ## Context Compression
 
+Hermes automatically compresses long conversations to stay within your model's context window. The compression summarizer is a separate LLM call — you can point it at any provider or endpoint.
+
+All compression settings live in `config.yaml` (no environment variables).
+
+### Full reference
+
+```yaml
+compression:
+  enabled: true                                     # Toggle compression on/off
+  threshold: 0.50                                   # Compress at this % of context limit
+  summary_model: "google/gemini-3-flash-preview"    # Model for summarization
+  summary_provider: "auto"                          # Provider: "auto", "openrouter", "nous", "codex", "main", etc.
+  summary_base_url: null                            # Custom OpenAI-compatible endpoint (overrides provider)
+```
+
+### Common setups
+
+**Default (auto-detect) — no configuration needed:**
 ```yaml
 compression:
   enabled: true
-  threshold: 0.50              # Compress at 50% of context limit by default
-  summary_model: "google/gemini-3-flash-preview"   # Model for summarization
-  # summary_provider: "auto"   # "auto", "openrouter", "nous", "main"
+  threshold: 0.50
 ```
+Uses the first available provider (OpenRouter → Nous → Codex) with Gemini Flash.
+
+**Force a specific provider** (OAuth or API-key based):
+```yaml
+compression:
+  summary_provider: nous
+  summary_model: gemini-3-flash
+```
+Works with any provider: `nous`, `openrouter`, `codex`, `anthropic`, `main`, etc.
+
+**Custom endpoint** (self-hosted, Ollama, zai, DeepSeek, etc.):
+```yaml
+compression:
+  summary_model: glm-4.7
+  summary_base_url: https://api.z.ai/api/coding/paas/v4
+```

+| `auto` (default) | not set | Auto-detect best available provider |

+| `model` | Which model to request | provider's default |

+
+When `base_url` is set, Hermes ignores the provider and calls that endpoint directly (using `api_key` or `OPENAI_API_KEY` for auth). When only `provider` is set, Hermes uses that provider's built-in auth and base URL.
+
+Available providers: `auto`, `openrouter`, `nous`, `codex`, `anthropic`, `main`, `zai`, `kimi-coding`, `minimax`, and any provider registered in the [provider registry](/docs/reference/environment-variables).

+description: "Expose hermes-agent as an OpenAI-compatible API for any frontend"
+---
+
+# HTTP Server
+
+The HTTP server exposes hermes-agent as an OpenAI-compatible HTTP endpoint. Any frontend that speaks the OpenAI format — Open WebUI, LobeChat, LibreChat, NextChat, ChatBox, and hundreds more — can connect to hermes-agent and use it as a backend.
+
+Your agent handles requests with its full toolset (terminal, file operations, web search, memory, skills) and returns the final response. Tool calls execute invisibly server-side.
+
+## Quick Start
+
+### 1. Enable the HTTP server
+
+Add to `~/.hermes/.env`:
+
+```bash
+HTTP_SERVER_ENABLED=true
+```
+
+### 2. Start the gateway
+
+```bash
+hermes gateway
+```
+
+You'll see:
+
+```
+[HTTP Server] HTTP server listening on http://127.0.0.1:8642
+```
+
+### 3. Connect a frontend
+
+Point any OpenAI-compatible client at `http://localhost:8642/v1`:
+
+```bash
+# Test with curl
+curl http://localhost:8642/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -d '{"model": "hermes-agent", "messages": [{"role": "user", "content": "Hello!"}]}'
+```
+
+Or connect Open WebUI, LobeChat, or any other frontend — see the [Open WebUI integration guide](/docs/user-guide/messaging/open-webui) for step-by-step instructions.
+
+## Endpoints
+
+### POST /v1/chat/completions
+
+Standard OpenAI Chat Completions format. Stateless — the full conversation is included in each request via the `messages` array.
+
+**Request:**
+```json
+{
+  "model": "hermes-agent",
+  "messages": [
+    {"role": "system", "content": "You are a Python expert."},
+    {"role": "user", "content": "Write a fibonacci function"}
+  ],
+  "stream": false
+}
+```
+
+**Response:**
+```json
+{
+  "id": "chatcmpl-abc123",
+  "object": "chat.completion",
+  "created": 1710000000,
+  "model": "hermes-agent",
+  "choices": [{
+    "index": 0,
+    "message": {"role": "assistant", "content": "Here's a fibonacci function..."},
+    "finish_reason": "stop"
+  }],
+  "usage": {"prompt_tokens": 50, "completion_tokens": 200, "total_tokens": 250}
+}
+```
+
+**Streaming** (`"stream": true`): Returns Server-Sent Events (SSE) with token-by-token response chunks. When streaming is enabled in config, tokens are emitted live as the LLM generates them. When disabled, the full response is sent as a single SSE chunk.
+
+### POST /v1/responses
+
+OpenAI Responses API format. Supports server-side conversation state via `previous_response_id` — the server stores full conversation history (including tool calls and results) so multi-turn context is preserved without the client managing it.
+
+**Request:**
+```json
+{
+  "model": "hermes-agent",
+  "input": "What files are in my project?",
+  "instructions": "You are a helpful coding assistant.",
+  "store": true
+}
+```
+
+**Response:**
+```json
+{
+  "id": "resp_abc123",
+  "object": "response",
+  "status": "completed",
+  "model": "hermes-agent",
+  "output": [
+    {"type": "function_call", "name": "terminal", "arguments": "{\"command\": \"ls\"}", "call_id": "call_1"},
+    {"type": "function_call_output", "call_id": "call_1", "output": "README.md src/ tests/"},
+    {"type": "message", "role": "assistant", "content": [{"type": "output_text", "text": "Your project has..."}]}
+  ],
+  "usage": {"input_tokens": 50, "output_tokens": 200, "total_tokens": 250}
+}
+```
+
+#### Multi-turn with previous_response_id
+
+Chain responses to maintain full context (including tool calls) across turns:
+
+```json
+{
+  "input": "Now show me the README",
+  "previous_response_id": "resp_abc123"
+}
+```
+
+The server reconstructs the full conversation from the stored response chain — all previous tool calls and results are preserved.
+
+#### Named conversations
+
+Use the `conversation` parameter instead of tracking response IDs:
+
+```json
+{"input": "Hello", "conversation": "my-project"}
+{"input": "What's in src/?", "conversation": "my-project"}
+{"input": "Run the tests", "conversation": "my-project"}
+```
+
+The server automatically chains to the latest response in that conversation. Like the `/title` command for gateway sessions.
+
+### GET /v1/responses/{id}
+
+Retrieve a previously stored response by ID.
+
+### DELETE /v1/responses/{id}
+
+Delete a stored response.
+
+### GET /v1/models
+
+Lists `hermes-agent` as an available model. Required by most frontends for model discovery.
+
+### GET /health
+
+Health check. Returns `{"status": "ok"}`.
+
+## System Prompt Handling
+
+When a frontend sends a `system` message (Chat Completions) or `instructions` field (Responses API), hermes-agent **layers it on top** of its core system prompt. Your agent keeps all its tools, memory, and skills — the frontend's system prompt adds extra instructions.
+
+This means you can customize behavior per-frontend without losing capabilities:
+- Open WebUI system prompt: "You are a Python expert. Always include type hints."
+- The agent still has terminal, file tools, web search, memory, etc.
+
+## Authentication
+
+Bearer token auth via the `Authorization` header:
+
+```
+Authorization: Bearer ***
+```
+
+Configure the key via `HTTP_SERVER_KEY` env var. If no key is set, all requests are allowed (for local-only use).
+
+:::warning Security
+The HTTP server gives full access to hermes-agent's toolset, **including terminal commands**. If you change the bind address to `0.0.0.0` (network-accessible), **always set `HTTP_SERVER_KEY`** — without it, anyone on your network can execute arbitrary commands on your machine.
+
+The default bind address (`127.0.0.1`) is safe for local-only use.
+:::
+
+## Configuration
+
+### Environment Variables
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `HTTP_SERVER_ENABLED` | `false` | Enable the HTTP server |
+| `HTTP_SERVER_PORT` | `8642` | HTTP server port |
+| `HTTP_SERVER_HOST` | `127.0.0.1` | Bind address (localhost only by default) |
+| `HTTP_SERVER_KEY` | _(none)_ | Bearer token for auth |
+
+### config.yaml
+
+```yaml
+# Not yet supported — use environment variables.
+# config.yaml support coming in a future release.
+```
+
+## CORS
+
+The HTTP server includes CORS headers on all responses (`Access-Control-Allow-Origin: *`), so browser-based frontends can connect directly.
+
+## Compatible Frontends
+
+Any frontend that supports the OpenAI API format works. Tested/documented integrations:
+
+| Frontend | Stars | Connection |
+|----------|-------|------------|
+| [Open WebUI](/docs/user-guide/messaging/open-webui) | 126k | Full guide available |
+| LobeChat | 73k | Custom provider endpoint |
+| LibreChat | 34k | Custom endpoint in librechat.yaml |
+| AnythingLLM | 56k | Generic OpenAI provider |
+| NextChat | 87k | BASE_URL env var |
+| ChatBox | 39k | API Host setting |
+| Jan | 26k | Remote model config |
+| HF Chat-UI | 8k | OPENAI_BASE_URL |
+| big-AGI | 7k | Custom endpoint |
+| OpenAI Python SDK | — | `OpenAI(base_url="http://localhost:8642/v1")` |
+| curl | — | Direct HTTP requests |
+
+## Limitations
+
+- **Response storage is in-memory** — stored responses (for `previous_response_id`) are lost on gateway restart. Max 100 stored responses (LRU eviction).
+- **No file upload** — vision/document analysis via uploaded files is not yet supported through the API.
+- **Model field is cosmetic** — the `model` field in requests is accepted but the actual LLM model used is configured server-side in config.yaml.

+# Open WebUI Integration
+
+[Open WebUI](https://github.com/open-webui/open-webui) (126k★) is the most popular self-hosted chat interface for AI. With Hermes Agent's built-in HTTP server, you can use Open WebUI as a polished web frontend for your agent — complete with conversation management, user accounts, and a modern chat interface.
+
+## Architecture
+
+```
+┌──────────────────┐    POST /v1/chat/completions    ┌──────────────────────┐
+│   Open WebUI     │ ──────────────────────────────► │  hermes-agent        │
+│   (browser UI)   │    SSE streaming response       │  gateway HTTP server  │

+└──────────────────┘                                  └──────────────────────┘
+```
+
+Open WebUI connects to Hermes Agent's HTTP server just like it would connect to OpenAI. Your agent handles the requests with its full toolset — terminal, file operations, web search, memory, skills — and returns the final response.
+
+## Quick Setup
+
+### 1. Enable the HTTP server
+
+Add to `~/.hermes/.env`:
+
+```bash
+HTTP_SERVER_ENABLED=true
+# Optional: set a key for auth (recommended if accessible beyond localhost)
+# HTTP_SERVER_KEY=your-secret-key
+```
+
+### 2. Start Hermes Agent gateway
+
+```bash
+hermes gateway
+```
+
+You should see:
+
+```
+[HTTP Server] HTTP server listening on http://127.0.0.1:8642
+```
+
+### 3. Start Open WebUI
+
+```bash
+docker run -d -p 3000:8080 \
+  -e OPENAI_API_BASE_URL=http://host.docker.internal:8642/v1 \
+  -e OPENAI_API_KEY=not-needed \
+  --add-host=host.docker.internal:host-gateway \
+  -v open-webui:/app/backend/data \
+  --name open-webui \
+  --restart always \
+  ghcr.io/open-webui/open-webui:main
+```
+
+If you set an `HTTP_SERVER_KEY`, use it instead of `not-needed`:
+
+```bash
+-e OPENAI_API_KEY=your-secret-key
+```
+
+### 4. Open the UI
+
+Go to **http://localhost:3000**. Create your admin account (the first user becomes admin). You should see **hermes-agent** in the model dropdown. Start chatting!
+
+## Docker Compose Setup
+
+For a more permanent setup, create a `docker-compose.yml`:
+
+```yaml
+services:
+  open-webui:
+    image: ghcr.io/open-webui/open-webui:main
+    ports:
+      - "3000:8080"
+    volumes:
+      - open-webui:/app/backend/data
+    environment:
+      - OPENAI_API_BASE_URL=http://host.docker.internal:8642/v1
+      - OPENAI_API_KEY=not-needed
+    extra_hosts:
+      - "host.docker.internal:host-gateway"
+    restart: always
+
+volumes:
+  open-webui:
+```
+
+Then:
+
+```bash
+docker compose up -d
+```
+
+## Configuring via the Admin UI
+
+If you prefer to configure the connection through the UI instead of environment variables:
+
+1. Log in to Open WebUI at **http://localhost:3000**
+2. Click your **profile avatar** → **Admin Settings**
+3. Go to **Connections**
+4. Under **OpenAI API**, click the **wrench icon** (Manage)
+5. Click **+ Add New Connection**
+6. Enter:
+   - **URL**: `http://host.docker.internal:8642/v1`
+   - **API Key**: your key or any non-empty value (e.g., `not-needed`)
+7. Click the **checkmark** to verify the connection
+8. **Save**
+
+The **hermes-agent** model should now appear in the model dropdown.
+
+:::warning
+Environment variables only take effect on Open WebUI's **first launch**. After that, connection settings are stored in its internal database. To change them later, use the Admin UI or delete the Docker volume and start fresh.
+:::
+
+## API Type: Chat Completions vs Responses
+
+Open WebUI supports two API modes when connecting to a backend:
+
+| Mode | Format | When to use |
+|------|--------|-------------|
+| **Chat Completions** (default) | `/v1/chat/completions` | Recommended. Works out of the box. |
+| **Responses** (experimental) | `/v1/responses` | For server-side conversation state via `previous_response_id`. |
+
+### Using Chat Completions (recommended)
+
+This is the default and requires no extra configuration. Open WebUI sends standard OpenAI-format requests and Hermes Agent responds accordingly. Each request includes the full conversation history.
+
+### Using Responses API
+
+To use the Responses API mode:
+
+1. Go to **Admin Settings** → **Connections** → **OpenAI** → **Manage**
+2. Edit your hermes-agent connection
+3. Change **API Type** from "Chat Completions" to **"Responses (Experimental)"**
+4. Save
+
+With the Responses API, Open WebUI sends requests in the Responses format (`input` array + `instructions`), and Hermes Agent can preserve full tool call history across turns via `previous_response_id`.
+
+:::note
+Open WebUI currently manages conversation history client-side even in Responses mode — it sends the full message history in each request rather than using `previous_response_id`. The Responses API mode is mainly useful for future compatibility as frontends evolve.
+:::
+
+## How It Works
+
+When you send a message in Open WebUI:
+
+1. Open WebUI sends a `POST /v1/chat/completions` request with your message and conversation history
+2. Hermes Agent creates an AIAgent instance with its full toolset
+3. The agent processes your request — it may call tools (terminal, file operations, web search, etc.)
+4. Tool calls happen invisibly server-side
+5. The agent's final text response is returned to Open WebUI
+6. Open WebUI displays the response in its chat interface
+
+Your agent has access to all the same tools and capabilities as when using the CLI or Telegram — the only difference is the frontend.
+
+## Configuration Reference
+
+### Hermes Agent (HTTP server)
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `HTTP_SERVER_ENABLED` | `false` | Enable the HTTP server |
+| `HTTP_SERVER_PORT` | `8642` | HTTP server port |
+| `HTTP_SERVER_HOST` | `127.0.0.1` | Bind address |
+| `HTTP_SERVER_KEY` | _(none)_ | Bearer token for auth. No key = allow all. |
+
+### Open WebUI
+
+| Variable | Description |
+|----------|-------------|
+| `OPENAI_API_BASE_URL` | Hermes Agent's API URL (include `/v1`) |
+| `OPENAI_API_KEY` | Must be non-empty. Match your `HTTP_SERVER_KEY`. |
+
+## Troubleshooting
+
+### No models appear in the dropdown
+
+- **Check the URL has `/v1` suffix**: `http://host.docker.internal:8642/v1` (not just `:8642`)
+- **Verify the gateway is running**: `curl http://localhost:8642/health` should return `{"status": "ok"}`
+- **Check model listing**: `curl http://localhost:8642/v1/models` should return a list with `hermes-agent`
+- **Docker networking**: From inside Docker, `localhost` means the container, not your host. Use `host.docker.internal` or `--network=host`.
+
+### Connection test passes but no models load
+
+This is almost always the missing `/v1` suffix. Open WebUI's connection test is a basic connectivity check — it doesn't verify model listing works.
+
+### Response takes a long time
+
+Hermes Agent may be executing multiple tool calls (reading files, running commands, searching the web) before producing its final response. This is normal for complex queries. The response appears all at once when the agent finishes.
+
+### "Invalid API key" errors
+
+Make sure your `OPENAI_API_KEY` in Open WebUI matches the `HTTP_SERVER_KEY` in Hermes Agent. If no key is configured on the Hermes side, any non-empty value works.

+## Linux Docker (no Docker Desktop)
+
+On Linux without Docker Desktop, `host.docker.internal` doesn't resolve by default. Options:
+
+```bash
+# Option 1: Add host mapping
+docker run --add-host=host.docker.internal:host-gateway ...
+
+# Option 2: Use host networking
+docker run --network=host -e OPENAI_API_BASE_URL=http://localhost:8642/v1 ...
+
+# Option 3: Use Docker bridge IP
+docker run -e OPENAI_API_BASE_URL=http://172.17.0.1:8642/v1 ...
+```
