Disciplined wine purchase evaluation framework for building a learning-focused cellar with limited storage. Use this skill when evaluating wine purchases from any source (retailers, flash sales, screenshots, PDFs, marathons). Triggers include requests to evaluate/assess/analyze wine purchases, make buy/pass decisions, review flash sales, or compare multiple wine offers. Provides structured BUY/CONSIDER/PASS verdicts with scoring, market analysis, and cellar fit assessment.
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
# Wine Purchase Evaluator This skill uses preferences from `references/preferences.md` if available. If no preferences file exists, apply the framework with reasonable defaults and ask the user about their specific constraints. This skill provides a rigorous, storage-aware framework for evaluating wine purchases with a focus on educational value, quality-to-price ratio (QPR), and cellar discipline. ## Core Philosophy **Default stance: PASS** Every wine must earn its place against: - Limited storage (fridge + cabinet + racks) - Budget constraints - Your learning priorities - Existing cellar inventory **Guiding principles:** - Discipline beats curiosity - Rotation beats accumulation - Learning value trumps status/prestige - True market price matters, not claimed retail - Half bottles are educational dead-ends - Known producers over marketing hype ## Evaluation Workflow ### 1. Auto-Detect Evaluation Type Determine evaluation mode from input: **Single Wine** (most common): - Input: Wine name + price + retailer - Output: Tight format (verdict, bullets, scores) - Example: "Domaine Besson Chablis Vaillons 1er Cru 2022 $30 LastBottle" **Multiple Wines**: …

How to install
mdr add slavins-co/cellartracker-mcp/wine-purchase-evaluator@sha256:1b845d3b8e7b4ae4The line at the top of this page pins the label git:20260712.da6a62d, 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.
