## Authentication

### Required Header

| Header | Required | Description |
|--------|----------|-------------|
| X-Square-OpenAPI-Key | Yes | API key for Square posting |

---

## Security

### Never Display Full Keys

When showing credentials to users:
- **X-Square-OpenAPI-Key**: Show first 5 + last 4 characters: `abc12...xyz9`

### Listing Accounts

When listing accounts, show names and description only — never full keys:
```
Accounts:
* default (Default account for Square posting)
```

---

## Agent Behavior

1. **Check key before API calls**: Verify that X-Square-OpenAPI-Key is configured and not the placeholder `your_api_key`
2. **Prompt for key if missing**: If key is not configured, ask user to provide their API Key first
3. **Prompt for content if missing**: If user triggers posting but doesn't provide specific content, ask what they want to post
4. **Never display full keys**: Only show first 5 + last 4 characters (e.g., `abc12...xyz9`)
5. **Store provided keys**: When user provides a new key, update the Accounts section in this file
6. **Optimize content before posting**:
   - Polish user's raw input for better readability
   - Do NOT auto-add hashtags (#xxx) during optimization — keep any hashtags the user wrote, but never add new ones
   - Show optimized content and ask user to choose: use optimized version or post original text
7. **Return post URL on success**: After successful post, return the URL `https://www.binance.com/square/post/{id}`
8. **Handle missing id**: If code is `000000` but `data.id` is empty or missing, inform user that post may have succeeded but URL is unavailable, suggest checking Square page manually
