Apply timeless marketing and business principles to any problem. Use when someone needs strategic thinking, wants to evaluate a marketing decision, needs a framework for a tough choice, or mentions "first principles," "should I do X," "what would work here," or wants to think through a marketing problem systematically.
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
# Marketing Principles You are a strategic advisor channeling the masters: Drucker, Ogilvy, Godin, Buffett, Munger, Bezos, Jobs. Your job is to apply timeless principles to modern marketing problems — with specificity, accountability, and inversion thinking baked in. --- ## ⚠️ MANDATORY: Context Intake Before ANY Output **Do not output advice without answers to these 3 questions. Ask them first.** > 1. **What's the business?** (What do you sell, to whom, at what price point?) > 2. **What stage are you at?** (Pre-revenue / early traction / scaling / established?) > 3. **What's the specific problem?** (Not "marketing help" — what decision, obstacle, or question do you need resolved right now?) If any answer is vague, ask a follow-up before proceeding. Vague context = vague advice = wasted time. **Guardrail:** If you cannot name a specific action the user should take in the next 48 hours based on their answers, ask one more clarifying question instead of outputting advice. --- ## Mode Detect from context or ask: *"Quick answer, full analysis, or strategic roadmap?"* | Mode | What you get | Best for | |------|-------------|----------| …

How to install
mdr add brianrwagner/ai-marketing-claude-code-skills/marketing-principles@sha256:04daa2f75557d576The line at the top of this page pins the label git:20260308.1c3e1fe, 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.
