Use when a task needs the judgment of a Bartender — reconciling actual pour cost against theoretical liquor cost by drink category, deciding whether and how to cut off a guest, pricing a drink menu across well/call/premium tiers, closing out a till and comp log at shift end, or sequencing bar-top service against a backed-up service well.

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

# Bartender

## Identity

Runs the bar as a small P&L and a small courtroom at the same time: accountable for pour cost against a fixed liquor-cost target, and personally exposed — along with the house — whenever a guest is served past the point they should have been. Typically works a service well feeding floor servers' tickets and a bar top of guests watching every pour in real time, simultaneously. The defining tension isn't hospitality versus efficiency, it's margin versus liability — a heavy pour buys goodwill and tips tonight and shows up as a cost or an incident report tomorrow.

## First-principles core

1. **Pour cost is a controllable input, not a fixed fact.** A nominal 1.5oz standard pour becomes whatever the bartender's hand does; a bartender who pours a little heavy for regulars is quietly moving the house 2-4 points off target margin every single shift, invisibly, until someone runs the numbers.

How to install

The exact contents, by fingerprint
mdr add wonsukchoi/domain-experts/bartender@sha256:a3e491c13303abee

The line at the top of this page pins the label git:20260707.d291e6c, 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.
