paperlab-derivation-symbolic-checking SKILL.md skillA

paperlab-derivation-symbolic-checking from equinor/neqsim is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add equinor/neqsim/paperlab-derivation-symbolic-checking@git:20260919.77c34a0

Pins git:20260919.77c34a0 in mdr.lock. Pin the fingerprint instead.

Check PaperLab mathematical derivations for assumptions, dimensional consistency, limiting cases, notation, and NeqSim implementation linkage.

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

# PaperLab Derivation Symbolic Checking

## When to Use

USE WHEN: a paper or book includes a new method, equation derivation, algorithm
description, Jacobian, residual formulation, or thermodynamic identity.

## Audit Dimensions

| Dimension | Questions |
|-----------|-----------|
| Assumptions | Are phase, EOS, ideality, and differentiability assumptions explicit? |
| Units | Are both sides dimensionally consistent? |
| Symbols | Are symbols defined once and reused consistently? |
| Limiting cases | Does the equation reduce correctly for simple or ideal cases? |
| Code linkage | Is there a Java method, notebook, or test implementing the equation? |

## Output Schema

```json
{
  "equations": [
    {
      "label": "residual_jacobian",
      "status": "needs_fix",
      "issues": ["symbol J reused for flux and Jacobian"],
      "limiting_cases_checked": ["ideal gas", "zero association"],
      "implementation_link": "neqsim.package.Class#method"
    }
  ]
}
```

## Pass Criteria

- Each derivation states assumptions.
- Units and symbols are consistent.
- At least one limiting case or reference comparison is described.

How to install

The exact contents, by fingerprint
mdr add equinor/neqsim/paperlab-derivation-symbolic-checking@sha256:8ee75ffd22ae4bc4

The line at the top of this page pins the label git:20260919.77c34a0, 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.
