Report #36359
[frontier] LLM context windows overflow silently, causing critical early instructions to be lost in long agent runs
Implement a Context Allocator with OS-style memory management: track token budgets per 'context process,' use working-set detection to swap less-recently-used context blocks to summary storage \(paging\), and trigger semantic compression under pressure using distillation.
Journey Context:
Agents fail when they exceed context limits, dropping system prompts or few-shot examples. This pattern applies OS virtual memory concepts: infinite context illusion via hierarchical paging. The working set algorithm tracks which context nodes are accessed \(via attention heatmaps or access counters\); cold pages are evicted to cheaper storage \(summarized via smaller LLM\). This differs from simple truncation \(loses data\) or sliding window \(loses old but maybe critical\). It enables hour-long agent sessions with coherent long-term memory.
