About this paper
Harish Gaggar
The authors evaluate protocol-aware trimming and adaptive guardrails for long histories in tool-using workflows. The methods preserve information needed for valid future actions while trimming redundant or inactive context; adaptive guardrails adjust retention with risk. At retained-context budgets of 35% or less, protocol-aware trimming had 5.24-fold greater task-success odds than conventional trimming, but results do not establish a safe budget.
Key insights
- Context in agentic systems functions partly as executable state: semantic similarity alone is insufficient when exact identifiers, constraints, authorization conditions, and state transitions determine whether a tool action is valid.
- Retaining 25% or less of the original context increased failure odds 10.92-fold relative to budgets of at least 50%, demonstrating a nonlinear failure regime.
- Safe compression depends on workflow complexity and dependency density; adaptive management lowered critical thresholds more effectively than fixed-budget strategies.
