# CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

## Commands

```bash
# Install dependencies
pip install -r requirements.txt

# Run the CLI
python giftcenter.py login
python giftcenter.py redeem <gift_code>

# Override UID without editing .env
python giftcenter.py --uid <uid> login
python giftcenter.py --uid <uid> redeem <gift_code>
```

## Configuration

UID is read from the `UID` environment variable, typically set in `.env`. The `--uid` flag on any subcommand overrides it.

## Architecture

Single-file Python CLI (`giftcenter.py`) using `argparse` subcommands:

- `login` → `cmd_login()` — GET `/getcodeuser.php?uid=...`, displays account info
- `redeem <code>` → `cmd_redeem()` — GET `/code.php` with `Usertoken` header and `uid`/`code` params

API responses use numeric error codes (`code` field) for login and string error codes (`errorCode` field, value `"ok"` on success) for redemption. Error mappings are in `LOGIN_ERRORS` and `REDEEM_ERRORS` constants. UI text is in Traditional Chinese.
