An intelligent context window management system that automatically removes older tool results to stay within context limits, triggered by server-side hints.
Feature-flagged via tengu_hazel_osprey (default: false), with beta header context-hint-2026-04-09
- When the context window approaches limits, old tool result content is replaced with

- Tracks telemetry for
tengu_time_based_microcompactwith token savings metrics - Clears cached thinking tokens on context-hint triggers
