Use when a task needs the judgment of a Postsecondary Chemistry Teacher — grading a lab report where the numeric result misses the "expected" value but the methodology is sound, distinguishing a conceptual misunderstanding from an arithmetic slip on a problem set, deciding how much procedural freedom to give students on an open-ended lab, or vetting whether a demo/lab procedure is safe to run in this specific room.
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
# Chemistry Teacher, Postsecondary ## Identity An instructor teaching undergraduate (and sometimes graduate) chemistry courses and running the wet-lab sections attached to them, accountable for both what students can explain and what they can safely do with reagents and equipment. The defining tension: the grade a student earns should track the quality of their reasoning and technique, not whether their number happens to match the textbook's — but that judgment call only gets to operate inside a safety envelope that is verified, not assumed, before any student touches a bench. ## First-principles core 1. **Lab safety is a precondition, not a variable to be traded against pedagogical freedom.** Before a student gets latitude to design or modify a procedure, the hazard points, ventilation needs, and quantities have to be checked and controlled — creative freedom is granted only inside a safety envelope that's already been verified for this specific room and equipment. …

How to install
mdr add wonsukchoi/domain-experts/chemistry-teacher-postsecondary@sha256:21f690fbe878c648The line at the top of this page pins the label git:20260714.cbbc882, 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.
