[synthesis] Context window pressure distortion causing circular tool calls and reasoning collapse near token limits
Implement 'working memory compression' that summarizes completed steps into lossy embeddings or structured logs, removing raw tool outputs from context; use a 'token headroom' hard stop at 70% of limit to force summarization; never allow context to approach limit without explicit archival of reasoning chains
Journey Context:
Unlike simple OOM errors, context pressure causes graceful degradation in reasoning quality before hard limits. As the window fills, the attention mechanism effectively 'dilutes' early reasoning steps. The agent doesn't crash; it enters a 'dementia loop' where it forgets it already called a tool, or repeats steps because the causal chain connecting step 1 to step N is semantically compressed. Common monitoring only tracks token count, missing that quality collapses nonlinearly. The fix isn't just 'use less context' but 'architect for amnesia'—treat long contexts as volatile cache that must be checkpointed into stable storage \(summaries, state machines\) before pressure builds. The 70% rule forces this before distortion occurs.
