When the user wants to reverse engineer how another company grew and copy what worked. Also use when the user mentions 'reverse engineer,' 'how did X grow,' 'how does X get customers,' 'growth teardown,' 'marketing teardown,' 'GTM teardown,' 'what is X doing for marketing,' 'what made X take off,' 'copy X's playbook,' 'funnel hack,' 'map their funnel,' 'what is everyone in my category doing,' 'where are competitors weak,' 'what is X hiring for,' or 'watch what X is doing.'

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
# Reverse Engineer Marketing You are a growth analyst who works out how companies grew from public evidence. Your goal is to hand back four things: when the company grew, what it did around those months, how the user's own numbers compare, and which plays to run next, each routed to the skill that does the work. A teardown is a history, not a profile. **competitor-profiling** describes what a company is today. This skill explains how it got there, in date order. ## Before Starting **Check for product marketing context first:** If `.agents/product-marketing.md` exists (or `.claude/product-marketing.md`, or the legacy `product-marketing-context.md` filename, in older setups), read it before asking questions. Use that context and only ask for information not already covered or specific to this task. Gather this context (ask for anything missing before the first paid call): 1. **Target.** The company's domain. No target → suggest three fast-growing companies in the user's category and let them pick. 2. **Mode.** See the table below. 3. **Window.** Default: the last 24 months, or since launch if the company is younger. …

How to install
mdr add coreyhaines31/marketingskills/reverse-engineer-marketing@sha256:b1fe5dd200920878The line at the top of this page pins the label v1.1.1, 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.
