Agents can repeat arguments, amplify an early false assumption, or converge because later participants trust prior messages more than primary evidence. A long transcript can create the impression of rigorous deliberation while adding little new information. Control these risks with source-first prompts, structured claims, independent checks where justified, maximum budgets, novelty tests, and a coordinator that can stop unproductive turns. Important facts should remain linked to sources rather than gain authority from repetition.
Another risk is social persuasion. One agent may use confident language that causes another to relax uncertainty or tool boundaries. System enforcement should not depend on participants respecting rhetorical instructions. Validate tool calls, permissions, schemas, and policies outside the dialogue. Keep approval decisions in a separate authority path. When the conversation contains sensitive or misleading content, retention and access should follow the task purpose rather than preserving every message indefinitely because it might be useful later.
Conversation memory needs its own boundary. A compact summary can help a resumed task, but it should identify which facts were verified, which claims were proposed, and which decisions were rejected. Replaying the entire transcript may reintroduce poisoned assumptions and unnecessary sensitive data. Treat summaries as derived context with provenance and expiration, not as authoritative records. The operating system should retrieve the current sources again when a material decision depends on them.
