 ## Key Implementation Details
 
+### oh-my-opencode Auto-Detection
+
+This plugin automatically disables itself when oh-my-opencode is detected to avoid conflicts (duplicate `skill` and `skill_mcp` tools).
+
+**Detection Logic:**
+1. Call `client.config.get()` via the OpenCode SDK to fetch the active config
+2. Check if `oh-my-opencode` is in the `plugin` array
+3. If found → return empty hooks (plugin does nothing)
+
+**User's Config Setup:**
+| Mode | Launch Command | Config File | Plugins |
+|------|----------------|-------------|---------|
+| Standard | `opencode` | `opencode.json` | `opencode-lazy-loader` (this plugin) |
+| OMO | `OPENCODE_CONFIG=~/.config/opencode/omo.json opencode` | `omo.json` | `oh-my-opencode` |
+
+**Developer Override:**
+Set `OPENCODE_LAZY_LOADER_FORCE=1` to force-enable the plugin even when oh-my-opencode is detected (for testing).

 ## Configuration Format
 
-The MCP configuration supports the standard format:
+The MCP configuration supports multiple formats for compatibility with both OpenCode and oh-my-opencode:
 
 ```typescript
 interface McpServerConfig {
-  command: string | string[];          // Command to execute (array recommended for args)
-  environment?: Record<string, string> // Environment variables
+  // Command formats (both supported):
+  command: string | string[]   // Array: ["npx", "-y", "@some/mcp"] or String: "npx"
+  args?: string[]              // Used with string command: ["-y", "@some/mcp"]
+
+  // Environment variable formats (both supported):
+  env?: Record<string, string> | string[]  // Object: { "KEY": "val" } or Array: ["KEY=val"]
+}
+```
+
+### Examples
+
+**Object format for env (recommended):**
+```json
+{
+  "my-server": {
+    "command": "npx",
+    "args": ["-y", "@some/mcp-server"],
+    "env": {
+      "API_KEY": "${MY_API_KEY}",
+      "DEBUG": "true"
+    }
+  }
+}
+```
+
+**Array format for env (OpenCode style):**
+```json
+{
+  "my-server": {
+    "command": ["npx", "-y", "@some/mcp-server"],
+    "env": ["API_KEY=${MY_API_KEY}", "DEBUG=true"]
+  }
 }
