ICP Builder

One LinkedIn URL in, a working GTM config out. This skill enriches the user's own profile via Crustdata and writes config/persona-profile.md + config/gtm-config.md — the files sales-prospecting and account-research read at startup.

Three steps, always in this order:

1. Stack (optional, fully skippable): which tools they use.
2. Persona: one LinkedIn URL; Crustdata turns it into who they are, what they sell, an inferred ICP, and their writing voice.
3. Write config + hand off.

Never interrogate the user. Do not ask "what do you sell", "who's your ICP", or "paste your voice emails". All of that is derived from the LinkedIn URL and their posts. The URL is the entire interview.
