Report #47008

[frontier] How do I prevent unbounded context growth in deep hierarchical agent systems?

Implement strict 'token envelope' budgeting where each agent subtask is allocated a hard token budget \(e.g., 4k tokens\) enforced by the framework; when the envelope is exhausted, the subtask must checkpoint and return a condensed summary rather than continuing.

Journey Context:
Common approaches truncate history or use summarization heuristics, but these fail in deep agent trees where context compounds exponentially. Token envelopes treat context as a managed resource like memory in OS processes, forcing agents to compress state at boundaries. The alternative—unbounded context—leads to catastrophic token costs and lost coherence in >3 level agent hierarchies.
