CRITICAL E005: Suspicious download URL detected in skill instructions.

• Suspicious download URL detected (high risk: 0.70). drive.google.com is a legitimate cloud storage service but is frequently used to host arbitrary files (including executables) by third parties and is a common vector for distributing malware unless the specific file and sender are verified and scanned.

MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

• Third-party content exposure detected (high risk: 0.80). The skill explicitly downloads and transcribes external Google Drive audio (Phase 1b: "Scan the daily note for Google Drive audio links" + download-gdrive.sh) and always reads Slack messages via slack_search_public_and_private / slack_read_channel (Phase 2b), and it uses those user-generated third-party contents to infer meetings, action items, and to update notes/todos—so untrusted content can directly influence tool actions.
