MechInterp Investigator

This skill guides a systematic investigation of SAE features to arrive at meaningful, non-trivial labels. It orchestrates the other mechinterp skills into a coherent research workflow.

Phase 0: Triage (ALWAYS START HERE)

Goal: Quickly filter out weak/auxiliary features that don't warrant deep investigation.

Time: 1-2 minutes

Many SAE features have minimal influence on model outputs. Triage identifies these early so you can skip expensive analysis.

Step 0.1: Check Decoder Weight Percentile
