    Cold Email Structure Checker

    Example session with this skill installed

    My LinkedIn enrichment column is returning null even though I'm passing valid profile URLs. The provider is Proxycurl and the mapping looks correct. Here is a sample input URL.

    • Read your context and instructions
    • Compiled the cold email structure

    Triage Report

    • Symptom Class: Null with valid inputs
    • Cause: Field casing mismatch. Proxycurl returns first_name but your column mapping is looking for firstName.
    • Fix: Update the extraction path to use snake_case.
    • Proof: Check the column preview; the value should now populate for the sample row.
