Report #45516

[synthesis] Agent B breaks Agent A's working solution because Agent A's handoff summary omitted the critical constraints that led to the solution

Instead of summarizing task completion, pass a structured 'constraint manifest' \(e.g., 'Constraints discovered: Do not use library X due to version conflict; Must use class Y for auth'\) between agents, alongside the code diff.

Journey Context:
Multi-agent frameworks use summarization to prevent context overflow during handoffs. However, summarization strips \*causal reasoning\*. Agent A might have tried approach 1, failed, and discovered a hidden constraint, leading to approach 2. Agent A hands off approach 2's code, but Agent B, lacking the constraint context, sees approach 2 as arbitrary, refactors it back to approach 1, and re-introduces the bug. The synthesis is that inter-agent communication must prioritize constraint transmission over narrative summarization, because constraints are the guardrails that prevent repeated failure, whereas summaries of success are brittle without them.
