## Error Handling & Resilience

The API client includes production-grade resilience features:

- **Timeouts**: All requests have a 30-second timeout via `AbortSignal`
- **Retries**: Automatic retry with exponential backoff (1s → 2s → 4s) for transient errors (HTTP 429, 5xx)
- **Rate Limiting**: Respects `Retry-After` headers; surfaces `x-ratelimit-remaining` in error messages
- **Structured Errors**: `ForemApiError` includes status code, endpoint, HTTP method, request ID, and rate-limit info

## Known Limitations

- **Reactions**: The `toggle_reaction` tool is currently disabled due to API 401 Unauthorized errors, likely caused by insufficient scopes on standard API keys. This feature may be re-enabled in a future release if API permissions are clarified.
- **Draft Articles**: Retrieval of draft articles via `get_article_by_id` uses a fallback mechanism (searching user's full article list) because the public endpoint does not support drafts. This ensures seamless access for authenticated users.

## Environment Variables

| Variable | Required | Description |
