What
An intelligent tool deferral system that tracks your tool usage patterns and only defers tools you haven't used recently, keeping frequently-used tools immediately available.
Status
Feature-flagged behind tengu_coral_whistle (default: true)
Details
- Tracks tool usage count and last-used timestamp in config (
toolUsage) - Uses a 7-day half-life decay function to compute a "recency-weighted usage score"
- Tools below the threshold are deferred (loaded on demand via ToolSearch)
- MCP tools are always deferred regardless of this flag
- When enabled, the
shouldDeferflag on a tool triggers the usage-based check
Evidence
tengu_coral_whistle feature flag, functions h84 (track usage), I84 (compute score with decay), b84 (check threshold) (search for "tengu_coral_whistle")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
