What it does when it runs

Pre-conversation research tool. Takes a name, company, or LinkedIn URL and generates a phone-readable cheat sheet with ICP fit, conversation strategy, objections to expect, and which proof points to use. Use before any meeting, call, or intentional conversation. Triggers on "research", "who is", "prep for meeting", "brief me on", "about to meet".

The source carries no licence at all, so no permission to redistribute it exists. Everything else on this page is our own reading of the file and is published here; the text of the skill is not, and stays where its author put it.
