+name: opencode-bridge
+description: Bridge between OpenWork UI and OpenCode runtime
+---
+
+## Overview
+
+OpenWork communicates with OpenCode via three mechanisms:
+
+1. **CLI invocation**: Spawn `opencode` with prompts and get JSON responses.
+2. **Database access**: Read OpenCode's SQLite database for sessions and messages.
+3. **MCP bridge**: Real-time bidirectional communication for streaming and permissions.
+
+## CLI Invocation
+
+### Non-interactive mode
+```bash
+opencode -p "your prompt" -f json -q
+```
+
+Returns JSON with the response content.
+
+### Flags
+| Flag | Description |
+|------|-------------|
+| `-p` | Prompt to execute |
+| `-f` | Output format (`text`, `json`) |
+| `-q` | Quiet mode (no spinner) |
+| `-c` | Working directory |
+| `-d` | Debug mode |
+
+### Example response
+```json
+{
+  "content": "Here is the result...",
+  "session_id": "abc123"
+}
+```
+
+## Database Access
+
+### Location
+```
+~/.opencode/opencode.db
+```
+
+Or project-local:
+```
+.opencode/opencode.db
+```
+
+### Schema (key tables)
+
+#### sessions
+```sql
+CREATE TABLE sessions (
+  id TEXT PRIMARY KEY,
+  parent_session_id TEXT,
+  title TEXT,
+  message_count INTEGER,
+  prompt_tokens INTEGER,
+  completion_tokens INTEGER,
+  summary_message_id TEXT,
+  cost REAL,
+  created_at INTEGER,
+  updated_at INTEGER
+);
+```
+
+#### messages
+```sql
+CREATE TABLE messages (
+  id TEXT PRIMARY KEY,
+  session_id TEXT,
+  role TEXT,  -- 'user', 'assistant', 'tool'
+  parts TEXT, -- JSON array of content parts
+  model TEXT,
+  created_at INTEGER,
+  updated_at INTEGER
+);
+```
+
+### Querying from Rust (Tauri)
+```rust
+use tauri_plugin_sql::{Migration, MigrationKind};
+
+#[tauri::command]
+async fn list_sessions(db: tauri::State<'_, Database>) -> Result<Vec<Session>, String> {
+    let sessions = sqlx::query_as::<_, Session>(
+        "SELECT * FROM sessions ORDER BY updated_at DESC"
+    )
+    .fetch_all(&db.pool)
+    .await
+    .map_err(|e| e.to_string())?;
+    
+    Ok(sessions)
+}
+```
+
+### Querying from SolidJS
+```tsx
+import Database from "@tauri-apps/plugin-sql";
+
+const db = await Database.load("sqlite:~/.opencode/opencode.db");
+const sessions = await db.select<Session[]>(
+  "SELECT * FROM sessions ORDER BY updated_at DESC"
+);
+```
+
+## MCP Bridge (Advanced)
+
+OpenWork can register as an MCP server that OpenCode connects to.
+
+### Configuration (opencode.json)
+```json
+{
+  "mcpServers": {
+    "openwork": {
+      "type": "stdio",
+      "command": "openwork-mcp-bridge"
+    }
+  }
+}
+```
+
+### Use cases
+- Real-time permission prompts surfaced in OpenWork UI.
+- Streaming progress updates.
+- Custom tools exposed from OpenWork (e.g., native file picker).
+
+## Message Content Parts
+
+Messages contain a `parts` JSON array with different content types:
+
+### TextContent
+```json
+{ "type": "text", "text": "Hello world" }
+```
+
+### ToolCall
+```json
+{
+  "type": "tool_call",
+  "id": "call_123",
+  "name": "bash",
+  "input": "{\"command\": \"ls\"}"
+}
+```
+
+### ToolResult
+```json
+{
+  "type": "tool_result",
+  "tool_call_id": "call_123",
+  "content": "file1.txt\nfile2.txt",
+  "is_error": false
+}
+```
+
+### Finish
+```json
+{
+  "type": "finish",
+  "reason": "end_turn",
+  "time": 1704067200
+}
+```
+
+## Common Gotchas
+
+- Database is SQLite; use read-only access to avoid conflicts with running OpenCode.
+- Message parts are JSON-encoded strings; parse them in the UI.
+- Session IDs are UUIDs; tool call IDs are also UUIDs.
+- Cost is in USD; tokens are raw counts.
+
+## First-Time Setup
+
+### Verify OpenCode is installed
+```bash
+which opencode
+opencode --version
+```
+
+### Verify database exists
+```bash
+ls ~/.opencode/opencode.db
+```
+
+### Test CLI invocation
+```bash
+opencode -p "Hello" -f json -q
+```
