What
When identical tool results appear multiple times in a conversation, subsequent occurrences are replaced with a short reference to the original, saving context window space.
Status
Feature-flagged behind tengu_onyx_basin_m1k (default: false)
Details
- Hashes tool result content and tracks seen results with short IDs (
r1,r2, etc.) - Duplicate results are replaced with:
<identical to result [rN] from your {tool} call earlier — refer to that output> - Only applies to results longer than 256 characters and shorter than a configurable max
- Tracks telemetry via
tengu_tool_result_dedup
Evidence
Tool result deduplication (gated by tengu_onyx_basin_m1k, search for "result-id:", "identical to result")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
