 # OpenCode Agent Guidelines

 - **Single test**: `bun test test/tool/tool.test.ts` (specific test file)
 
 ## Code Style
+
 - **Runtime**: Bun with TypeScript ESM modules
 - **Imports**: Use relative imports for local modules, named imports preferred
 - **Types**: Zod schemas for validation, TypeScript interfaces for structure
 - **Naming**: camelCase for variables/functions, PascalCase for classes/namespaces
 - **Error handling**: Use Result patterns, avoid throwing exceptions in tools
 - **File structure**: Namespace-based organization (e.g., `Tool.define()`, `Session.create()`)
+- DO NOT do unnecessary destructuring of variables
+- DO NOT use else statements unless necessary
+- DO NOT use try catch if it can be avoided
 
 ## Architecture
+
 - **Tools**: Implement `Tool.Info` interface with `execute()` method
 - **Context**: Pass `sessionID` in tool context, use `App.provide()` for DI
 - **Validation**: All inputs validated with Zod schemas
 - **Logging**: Use `Log.create({ service: "name" })` pattern
-- **Storage**: Use `Storage` namespace for persistence
