 After making changes, you can test your local build in OpenCode:
 
 1. **Build the project**:
+
    ```bash
    bun run build
    ```
 
 2. **Update your OpenCode config** (`~/.config/opencode/opencode.json` or `opencode.jsonc`):
+
    ```json
    {
-     "plugin": [
-       "file:///absolute/path/to/oh-my-opencode/dist/index.js"
-     ]
+     "plugin": ["file:///absolute/path/to/oh-my-opencode/dist/index.js"]
    }
    ```
-   
+
    For example, if your project is at `/Users/yourname/projects/oh-my-opencode`:
+
    ```json
    {
-     "plugin": [
-       "file:///Users/yourname/projects/oh-my-opencode/dist/index.js"

 ### Code Style & Conventions
 
-| Convention | Rule |
-|------------|------|
-| Package Manager | **Bun only** (`bun run`, `bun build`, `bunx`) |
-| Types | Use `bun-types`, not `@types/node` |
-| Directory Naming | kebab-case (`ast-grep/`, `claude-code-hooks/`) |
-| File Operations | Never use bash commands (mkdir/touch/rm) for file creation in code |
-| Tool Structure | Each tool: `index.ts`, `types.ts`, `constants.ts`, `tools.ts`, `utils.ts` |
-| Hook Pattern | `createXXXHook(input: PluginInput)` function naming |
-| Exports | Barrel pattern (`export * from "./module"` in index.ts) |

 **Anti-Patterns (Do Not Do)**:
+
 - Using npm/yarn instead of bun
 - Using `@types/node` instead of `bun-types`
 - Suppressing TypeScript errors with `as any`, `@ts-ignore`, `@ts-expect-error`
