Agent tools now keep user profile lookups behind approval and apply conversation scope to typing indicators.

Discord thread targets are checked against their parent channel, and private slash-command follow-ups stay private. Twilio direct messages no longer share history or scope across recipients.

Queued messages restore their own conversation context before handlers run. Callback tokens are bound to their action and conversation, expire sooner, and can only be used once.

Link preview metadata is clearly marked as untrusted and bounded before it reaches an AI prompt.

Agent tools now keep user profile lookups behind approval and apply conversation scope to typing indicators.
Discord thread targets are checked against their parent channel, and private slash-command follow-ups stay private. Twilio direct messages no longer share history or scope across recipients.
Queued messages restore their own conversation context before handlers run. Callback tokens are bound to their action and conversation, expire sooner, and can only be used once.
Link preview metadata is clearly marked as untrusted and bounded before it reaches an AI prompt.
