+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Common Development Commands
+
+### Build Commands
+- `npm run build` - Build the library using tshy (generates both ESM and CJS outputs)
+- `npm run build:clean` - Full rebuild including reference type generation from BigCommerce schemas
+- `npm run build:reference-types` - Generate TypeScript types from BigCommerce OpenAPI schemas
+- `npm run build:file-list` - Generate file list for schema processing
+- `npm run build:summarize-changes` - Generate changelog summary of interface changes
+
+### Testing and Quality
+- `npm test` - Run type tests using tsd
+- `npm run lint` - Run ESLint on TypeScript files
+
+### Important Notes
+- Node.js version requirement: >=20 (maintenance LTS)
+- The project uses Yarn 4 as package manager (`yarn install` to install dependencies)
+- TypeScript configuration extends `@aligent/ts-code-standards`
+
+## Architecture Overview
+
+### Type Generation Pipeline
+This library auto-generates TypeScript types from BigCommerce's OpenAPI schemas:
+
+1. **Schema Sources** (`src/internal/reference/`)
+   - YAML schemas are fetched from BigCommerce's official documentation repository
+   - Files listed in `files.json` are processed during build
+   - Blacklisted operations in `blacklist.json` are excluded
+
+2. **Generation Process** (`src/internal/reference/generate.js`)
+   - Uses `openapi-typescript` to convert YAML to TypeScript
+   - Applies custom AST transformations to fix BigCommerce schema issues
+   - Outputs to `src/internal/reference/generated/`
+   - Groups APIs by version (v2, v3, sf)
+
+3. **Type Augmentation** (`src/internal/augmentation.ts`)
+   - Removes methods not declared in schemas
+   - Makes Accept/Content-Type headers optional (handled automatically)
+   - Fixes incorrect response declarations
+
+### Client Structure
+
+The library provides a unified client with version-specific sub-clients:
+
+```
+Management.Client
+├── v2 (Management.V2.Client) - Legacy REST API
+└── v3 (Management.V3.Client) - Modern REST API with pagination
+```
+
+Each versioned client provides:
+- `send()` - Raw API calls with full response
+- `get()`, `post()`, `put()`, `delete()` - Convenience methods returning data directly
+- `list()` (v3 only) - Async iterator for paginated endpoints
+
+### Key Architectural Decisions
+
+1. **Transport Abstraction** (`src/internal/operation.ts`)
+   - Pluggable transport layer allows custom fetch implementations
+   - Built-in retry logic with exponential backoff for 429/5xx errors
+   - Automatic header management
+
+2. **Type Safety**
+   - Full TypeScript coverage for all endpoints
+   - Response narrowing based on status codes
+   - Custom endpoint support via generic type parameter
+
+3. **Module Structure**
+   - Generated types are kept separate from hand-written code
+   - Each API domain has its own generated file (e.g., `catalog/products_catalog.v3.ts`)
+   - Version-specific functionality isolated in v2/v3 directories
+
+### Working with Generated Code
+- Generated files in `src/internal/reference/generated/` should not be edited manually
+- To update schemas: run `npm run build:clean`
+- Schema changes are tracked in `docs/changelog/`
