+# Coding Standards for npmextra
+
+## Naming Conventions
+- **Interfaces**: Prefix with `I` (e.g., `IAppDataOptions`, `ITestOptions`)
+- **Types**: Prefix with `T` (e.g., `TKeyValueStore`)
+- **Filenames**: Always lowercase (e.g., `npmextra.classes.appdata.ts`)
+- **Module structure**: `npmextra.<type>.<name>.ts` pattern
+
+## Import/Export Patterns
+- Use ES module syntax (`import`/`export`)
+- Import all dependencies through `npmextra.plugins.ts`
+- Reference with full path: `plugins.moduleName.className()`
+- Export all public APIs through `index.ts`
+
+## TypeScript Patterns
+- Use generic types for flexibility (`<T = any>`)
+- Leverage TypeScript utility types from `@tsclass/tsclass`
+- Use async/await for asynchronous operations
+- Use Promises with smartpromise utilities
+
+## Testing Standards
+- Import expect from `@git.zone/tstest/tapbundle`
+- Test files end with `export default tap.start()`
+- Use descriptive test names with `tap.test()`
+- Test file naming: `test.*.ts` pattern
+
+## Code Quality
+- Make focused, goal-oriented changes
+- Preserve necessary complexity
+- Remove redundancy carefully
+- Keep async patterns where they add value
+- No comments unless explicitly requested

+# npmextra Project Overview
+
+## Purpose
+npmextra is a utility library that enhances npm with additional configuration and tool management capabilities. It provides a key-value store for project setups and centralized configuration management through npmextra.json files.
+
+## Tech Stack
+- TypeScript (ES modules)
+- Node.js
+- Dependencies:
+  - @push.rocks/qenv - Environment variable management
+  - @push.rocks/smartfile - File system operations
+  - @push.rocks/smartjson - JSON handling
+  - @push.rocks/smartlog - Logging
+  - @push.rocks/smartpath - Path utilities
+  - @push.rocks/smartpromise - Promise utilities
+  - @push.rocks/smartrx - Reactive programming
+  - @push.rocks/taskbuffer - Task management
+  - @tsclass/tsclass - TypeScript utilities
+
+## Main Components
+1. **Npmextra** - Main class for managing npmextra.json configurations
+2. **KeyValueStore** - Persistent key-value storage system
+3. **AppData** - Advanced data management with environment variable mapping
+
+## Project Structure
+- `ts/` - TypeScript source files
+- `test/` - Test files using @git.zone/tstest
+- `dist_ts/` - Compiled JavaScript output
+- `npmextra.json` - Project configuration
+- `package.json` - Node.js package configuration

+# Suggested Commands for npmextra Development
+
+## Build Commands
+- `pnpm run build` - Build the TypeScript project (uses tsbuild)
+- `pnpm test` - Run tests using tstest
+
+## Development Commands
+- `pnpm install` - Install dependencies
+- `pnpm install --save-dev <package>` - Add development dependencies  
+- `tsx <script>` - Run TypeScript files directly (tsx is globally available)
+
+## Git Commands
+- `git status` - Check current changes
+- `git add .` - Stage changes
+- `git commit -m "message"` - Commit changes (only when explicitly requested)
+- `git mv` - Move/rename files to preserve history
+
+## Testing
+- `pnpm test` - Run all tests
+- `tstest test/test.some.ts --verbose` - Run specific test file
+- Tests use @git.zone/tstest framework with tap-based structure
+
+## Type Checking
+- `pnpm run build` - Type check and build the project
+- `tsbuild check test/**/* --skiplibcheck` - Type check test files only
+
+## Directory Structure
+- Source code in `ts/` directory
+- Tests in `test/` directory  
+- Built output in `dist_ts/` directory
+- Temporary/debug files in `.nogit/` directory
