[frontier] How do I choose the right compression level for my agent's context window?

Make context compression budget-aware: pass the remaining token budget into the compression step so it preserves detail when budget is ample and compresses aggressively when budget is tight. Monitor token usage, set a compression trigger before the rot zone, and use stronger compression \(shorter summaries, higher pruning\) as the budget shrinks rather than a fixed compression ratio.

Journey Context:
Most agents compress history with a static heuristic, which over-compresses under relaxed budgets \(losing evidence\) and under-compresses under tight budgets \(overflowing\). The ContextBudget work shows that conditioning compression on the available budget improves long-horizon search and reasoning. This is emerging in 2026 because context windows are now large enough that fixed-ratio summarization is obviously wasteful, but model attention still degrades with length. Pair budget-aware compression with a pre-rot threshold and reversible compaction for best results.
