Covers depth limits that propagate through child instances, four independent circuit breakers (consecutive errors, budget, tokens, timeout) that each raise typed exceptions with partial answers, parallel sub-call batching via ThreadPoolExecutor, context compaction triggered at 85% of the model's context window, and a structured completion object that records the full recursive call tree. The key insight is that none of these mechanisms are exotic individually — together they form composable, gracefully-degrading guardrails for any recursive or multi-agent system. ## Full article daily.dev links to this article rather than hosting it.
