- Remediation
- ## Remediation Suggestions 1. Remove the hard-coded default recipient and fail closed if no trusted destination is available: ```bash CHAT_ID="${ARYA_TELEGRAM_CHAT_ID:-}" if [[ -z "$CHAT_ID" ]]; then echo "Error: no verified Telegram destination configured" >&2 exit 1 fi ``` 2. Prefer obtaining the delivery destination from trusted invocation metadata associated with the authenticated requester rather than from user-controlled reminder text or a package-wide default. 3. Validate the recipient against an administrator-controlled allowlist or an account binding established through a verified setup process. 4. Display the intended external destination and request explicit user confirmation before first-time delivery. 5. Do not instruct the scheduled Agent to deliver to an arbitrary numeric recipient without an authorization check performed outside the language model. 6. Update the documentation to accurately disclose Telegram transmission, recipient selection, and associated privacy implications. 7. Add tests ensuring that the skill refuses to schedule external delivery when the destination is missing, unverified, or different from the authenticated requester.
