Report #68408
[synthesis] Agent silently ignores early system instructions as context grows
Instrument step-compliance scoring per turn, not just final output; trigger alerts if early-step adherence drops while context token count rises above 60%.
Journey Context:
Teams monitor latency and error rates, which remain stable. The model doesn't fail; it just drops early constraints \(like 'use specific library X'\) because attention mechanisms degrade on the middle/early parts of long contexts. You only see this in retrospect when auditing why the agent suddenly switched libraries. Standard logging shows the full context was passed, but cannot measure attention distribution.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
