paperlab-derivation-symbolic-checking skillA
paperlab-derivation-symbolic-checking is agent-read markdown (skill) from equinor/neqsim: Check PaperLab mathematical derivations for assumptions, dimensional consistency, limiting cases, notation, and NeqSim implementation linkage..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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
mdr add equinor/neqsim/paperlab-derivation-symbolic-checking@git:20260919.77c34a0mdr add equinor/neqsim/paperlab-derivation-symbolic-checking@sha256:8ee75ffd22ae4bc4Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
