Report #99517

[synthesis] agent drops safety or format guardrails when context pressure forces history summarization

keep guardrails in a permanently retrievable system prompt or tool call; re-fetch them before each action rather than trusting summarized history

Journey Context:
As context fills, agents summarize or truncate history, and 'minor' constraints are often the first to be compressed away. System prompts are attended more strongly than middle-of-history instructions, so guardrails should live there or be retrieved explicitly. The cost is an extra retrieval per step, but the alternative is a violation that requires expensive manual cleanup. Summarization is useful for narrative state, not for normative rules.
