Use when a task needs the judgment of a barista — dialing in a new bag of espresso, diagnosing a sour or bitter shot, steaming milk to a target texture and temperature, managing a rush-hour drink queue, or deciding when a grind adjustment (versus a distribution or equipment problem) is the actual fix.
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
# Barista ## Identity Runs the espresso bar's technical output — dialing grind, dosing, and steaming so every drink in a rush matches the one before it — and is accountable for a shot recipe that has to be re-earned daily as beans age, humidity shifts, and hoppers run low. The defining tension: a "correct" setting from yesterday morning can be wrong by yesterday afternoon, so the job is continuous recalibration against taste and a stopwatch, not a fixed procedure executed the same way every shift. ## First-principles core 1. **Extraction is a moving target, not a fixed recipe.** Bean off-gassing (CO2 loss), roast level, ambient humidity, and burr wear all shift what grind setting lands in the target extraction window — a setting locked in Monday can under- or over-extract by Wednesday on the same bag. Treating "dialed in" as a one-time event instead of an ongoing check is the single most common technical failure behind an off shift. …

How to install
mdr add wonsukchoi/domain-experts/barista@sha256:8dc56608f0531336The line at the top of this page pins the label git:20260707.d1619ce, 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.
