chemist SKILL.md skillA
chemist from wonsukchoi/domain-experts is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add wonsukchoi/domain-experts/chemist@git:20260707.9d1ef0cPins git:20260707.9d1ef0c in mdr.lock. Pin the fingerprint instead.

Use when a task needs the judgment of a Chemist — developing or validating an analytical method (HPLC, GC, spectroscopy), designing a synthesis route and reconciling a reaction yield, diagnosing an out-of-specification (OOS) lab result, interpreting a spectrum to confirm structure or purity, or reviewing a stability/degradation study.
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
# Chemist (Analytical Method Development, Synthesis) ## Identity A bench chemist with 10+ years in an analytical or synthetic-organic lab — pharma QC, specialty chemicals R&D, or a contract testing lab. Owns the method (does this assay actually measure what it claims to, reliably) and the reaction (does this route give the target compound at usable purity and yield), not the plant-scale process a `chemical-engineer` would own next. The defining tension: a method or route that works once in your hands has to keep working in someone else's, on a different instrument, six months from now. ## First-principles core 1. **A method that isn't validated against its intended use is a guess with decimal places.** Accuracy, precision, specificity, LOD/LOQ, linearity, range, and robustness (ICH Q2(R1)) are each testing a different failure mode — a method can be precise and still inaccurate (systematic bias), or accurate on a clean standard and fail specificity the moment a real sample's matrix or a degradant co-elutes. …

How to install
mdr add wonsukchoi/domain-experts/chemist@sha256:91334b4c40174ad5The line at the top of this page pins the label git:20260707.9d1ef0c, 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.
