### Review Engines

| Engine | Description | Use Case |
|--------|-------------|----------|
| `agent` | Task-based staged review (`skip` / `light` / `full`) with scoped specialist routing and optional reflection/debate escalation | Deep reviews with token-aware execution |
| `codex` | Codex CLI review execution with independent configuration | External Codex-driven review pipeline |

## Quick Start

### Prerequisites

- [Bun](https://bun.sh/) >= 1.2.5
- Gitea instance with API access
- At least one LLM provider API key (OpenAI, Anthropic, Google Gemini, or any OpenAI-compatible endpoint)

### Installation

```bash
git clone https://github.com/user/gitea-ai-assistant.git
cd gitea-ai-assistant
bun install
```

### Configuration

Create a `.env` file with only infrastructure-level settings:

```bash
# Server port
PORT=3000

# REQUIRED: encryption key for API key storage (generate with: openssl rand -hex 32)
ENCRYPTION_KEY=

# Optional: custom database path (default shown)
# DATABASE_PATH=./data/assistant.db
```

> **All other configuration** (Gitea connection, webhook secret, admin password, review engine, Feishu, memory settings, etc.) is managed through the **Admin Dashboard Web UI** at `http://your-server:3000`. On first boot, all settings are seeded with secure defaults automatically.

See [Configuration Reference](#configuration-reference) for all options.

### Running

```bash
bun run dev    # Development mode
bun run start  # Production mode
```

### Setting Up Webhooks

**Option 1: Admin Dashboard (Recommended)**

1. Access `http://your-server:3000`
2. Log in with the admin password (default: `password` — change it in the dashboard)
3. Click "Enable" on repositories to auto-configure webhooks

**Option 2: Manual Configuration**

In Gitea repository settings, add a webhook:
- **URL**: `http://your-server:3000/webhook/gitea`
- **Content Type**: `application/json`
- **Secret**: Same as the Webhook Secret configured in the dashboard
- **Events**: "Pull Request" and "Status"
## Configuration Reference

### Environment Variables (Minimal)

Only infrastructure-level settings that must be known before the database is initialized:

| Variable | Description | Default |
|----------|-------------|---------|
| `PORT` | Server port | `5174` |
| `DATABASE_PATH` | SQLite database file path | `./data/assistant.db` |
| `ENCRYPTION_KEY` | **Required.** AES-256-GCM encryption key for API key storage (64 hex chars). Generate with `openssl rand -hex 32` | — |

### Web UI Configuration (Admin Dashboard)

All runtime configuration is managed through the **Admin Dashboard** at `http://your-server:PORT`. Changes take effect immediately without restart.

On first boot with an empty database, all settings are seeded with secure defaults:
- `JWT_SECRET` and `WEBHOOK_SECRET` are auto-generated (64-char hex via `crypto.randomBytes`)
- `ADMIN_PASSWORD` defaults to `password` — **change this immediately**

#### Gitea

| Setting | Description |
|---------|-------------|
| Gitea API URL | Gitea API endpoint (e.g. `https://gitea.example.com/api/v1`) |
| Access Token | Token for code review (read + comment permissions) |
| Admin Token | Token for webhook management (optional) |

#### Security

| Setting | Description | Default |
|---------|-------------|---------|
| Webhook Secret | HMAC-SHA256 webhook signature secret | Auto-generated |
| Admin Password | Dashboard login password | `password` |
| JWT Secret | JWT signing secret | Auto-generated |

#### LLM Provider Configuration

LLM providers and models are configured exclusively through the **Admin Dashboard** Web UI:

1. Navigate to **LLM 配置** (LLM Configuration)
2. Add your LLM providers (OpenAI Compatible, OpenAI Responses API, Anthropic, Google Gemini)
3. Assign models to review roles (planner, specialist, judge, embedding)

> API keys are stored encrypted (AES-256-GCM) in the local SQLite database.

#### Feishu Integration

| Setting | Description |
|---------|-------------|
| Feishu Webhook URL | Feishu bot webhook URL |
| Feishu Webhook Secret | Feishu webhook secret (optional) |

#### Agent Review Engine

| Setting | Description | Default |
|---------|-------------|---------|
| Review Engine | Engine mode (`agent` or `codex`) | `agent` |
| Enable Triage | Enable planner triage for task routing | `true` |
| Small Max Files | Upper file-count bound for `small` review size | `3` |
| Small Max Changed Lines | Upper changed-lines bound for `small` review size | `80` |
| Medium Max Files | Upper file-count bound for `medium` review size | `10` |
| Medium Max Changed Lines | Upper changed-lines bound for `medium` review size | `400` |
| Token Budget Small | Token budget cap for `small` staged tasks | `12000` |
| Token Budget Medium | Token budget cap for `medium` staged tasks | `45000` |
| Token Budget Large | Token budget cap for `large` staged tasks | `120000` |
| Review Work Directory | Working directory for repo clones | `/tmp/gitea-assistant` |
| Max Parallel Runs | Max concurrent review tasks | `2` |
| Max Files per Run | Max files analyzed per review | `200` |
| Auto-publish Min Confidence | Min confidence score for auto-publish | `0.8` |
| Enable Human Gate | Require human approval before publishing | `true` |

Agent review execution model (current):

- `skip`: docs/assets/rename-only style changes can bypass specialist review.
- `light`: low-risk code changes run minimal scoped specialist checks.
- `full`: sensitive or larger changes run full specialist tasks, with optional reflection/debate escalation.
- Triage outputs task scopes (`paths`, `riskTags`, `mode`, `tokenBudget`) and orchestrator dispatches specialists by task scope instead of broad fan-out.

#### Memory & Learning (Experimental)

| Setting | Description | Default |
|---------|-------------|---------|
| Qdrant URL | Qdrant vector database URL | - |
| Enable Memory | Enable memory system | `false` |
| Enable Reflection | Enable self-critique | `false` |
| Enable Debate | Enable multi-agent debate | `false` |
## Deployment

### Docker

```bash
docker build -t gitea-assistant .
docker run -d -p 3000:3000 -v ./data:/app/data -e PORT=3000 gitea-assistant
```

### Docker Compose

```bash
docker-compose up -d
```

### Kubernetes

Kubernetes manifests are located in the `k8s/` directory.

**1. Create the encryption secret**

```bash
# Generate a key and create the secret
kubectl apply -f k8s/namespace.yaml
ENCRYPTION_KEY=$(openssl rand -hex 32)
kubectl -n gitea-assistant create secret generic gitea-assistant-secret \
  --from-literal=ENCRYPTION_KEY=$ENCRYPTION_KEY
# Save this key! You'll need it if you ever redeploy.
echo "Your ENCRYPTION_KEY: $ENCRYPTION_KEY"
```

**2. Deploy**

```bash
kubectl apply -k k8s/
```

Or apply individually:

```bash
kubectl apply -f k8s/namespace.yaml
kubectl apply -f k8s/qdrant.yaml
kubectl apply -f k8s/gitea-assistant.yaml
```

**4. Verify**

```bash
kubectl -n gitea-assistant get pods
kubectl -n gitea-assistant get svc
```

**5. Expose the Service (optional)**

By default, services use `ClusterIP`. To expose externally, use an Ingress or change the Service type:

```bash
kubectl -n gitea-assistant patch svc gitea-assistant -p '{"spec":{"type":"NodePort"}}'
```
