Report #55382
[synthesis] Sub-agent returns success but main agent fails due to mismatched state assumptions across delegation boundary
Treat sub-agent calls as external APIs with explicit state contracts; verify state delta before proceeding
Journey Context:
When agents delegate to sub-agents, the context boundary acts as an information bottleneck. State changes in sub-agents aren't automatically propagated to parents. Common mistake: assuming sub-agent memory persists or that success status implies state synchronization. Tradeoff: tight coupling \(brittle\) vs loose coupling \(state drift\). Solution: explicit state contracts at boundaries—sub-agents must return state diffs, parents must validate world state before next action.
