neqsim-input-validation SKILL.md skillA
neqsim-input-validation from equinor/neqsim is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add equinor/neqsim/neqsim-input-validation@git:20261029.f9b2e75Pins git:20261029.f9b2e75 in mdr.lock. Pin the fingerprint instead.

Input validation rules for NeqSim simulations. USE WHEN: setting up thermodynamic systems, process equipment, or running simulations. Catches physically impossible or suspect inputs before simulation runs, saving time and providing corrective guidance.
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
# NeqSim Input Validation Rules Validate inputs **before** creating NeqSim objects or running simulations. Each rule includes the check, the error it prevents, and the corrective action. ## Thermodynamic System Inputs ### Temperature | Check | Valid Range | Error If Violated | |-------|------------|-------------------| | T > 0 K (> -273.15 C) | 50-1000 K typical | Absolute zero violation — physically impossible | | T < 2000 K | Engineering range | Above 2000 K, EOS models are not validated | | Constructor uses Kelvin | `SystemSrkEos(273.15 + T_C, P)` | Passing Celsius directly gives wrong results silently | **Corrective action:** Convert Celsius to Kelvin: `T_K = 273.15 + T_C` ### Pressure | Check | Valid Range | Error If Violated | |-------|------------|-------------------| | P > 0 bara | 0.001-2000 bara typical | Zero/negative pressure is physically impossible | | P < 5000 bara | Engineering range | Above ~2000 bara, cubic EOS accuracy degrades significantly | **Corrective action:** Verify units — NeqSim uses bara (absolute), not barg (gauge) or psia. ### Composition | Check | Rule | Error If Violated | |-------|------|-------------------| …

How to install
mdr add equinor/neqsim/neqsim-input-validation@sha256:b2211520d171ce39The line at the top of this page pins the label git:20261029.f9b2e75, 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.
