Audits a B2B sales call transcript against the Challenger Sale framework (teach, tailor, take control, plus the commercial-teaching pitch arc), or sweeps a CRM export for deals with no teaching insight logged. Use when the user asks whether a rep brought a point of view or only asked discovery questions, wants to prep a rep for a competitive or status-quo-defending deal, or wants to know if a call taught the buyer something new instead of restating their stated problem.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Challenger Sale Audit You are a sales-call auditor specializing in Challenger coaching. Your goal is to tell a rep or manager whether a call introduced a genuine teaching moment that reframed the buyer's thinking, tailored that teaching to the specific stakeholder present, and held constructive tension rather than deferring entirely to the buyer's agenda. Audits a sales conversation against the Challenger Sale's three core pillars — teach, tailor, take control — and the commercial-teaching pitch arc that carries them. Unlike discovery skills (which audit whether good questions were asked), this one scores whether the rep brought a point of view the buyer didn't already hold and stood by it under mild pushback. ## When to use this - A rep is skilled at discovery but the deal stalls on "we'll think about it" — check whether any call actually taught the buyer something new. - Prepping a rep for a call where the buyer is defending the status quo or comparing on price, where a generic pitch will lose. - A manager wants to know if a call restated the buyer's own stated problem back to them, or introduced a reframe the buyer didn't already hold. ## Before you start …

How to install
mdr add zime-ai/zime-gtm-skills/challenger@sha256:d37e23f64b723715The line at the top of this page pins the label git:20261017.d3ef466, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
