Why this is a false positive

The prompt requested developer onboarding documentation in Markdown for implementing a third-party API client, including standard cloud message deletion methods. The safeguard classifier flagged the prompt under the cyber safety filter upon encountering terms associated with remote API operations and message deletion. Documenting authorized API endpoints for application integration involves no exploit material, unauthorized access techniques, or malicious payloads.
