neqsim-cpa-water-boundaries SKILL.md skillA

neqsim-cpa-water-boundaries 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/neqsim-cpa-water-boundaries@git:20261030.b7ae1f4

Pins git:20261030.b7ae1f4 in mdr.lock. Pin the fingerprint instead.

Calculate and explain liquid-water, ice and hydrate onset temperatures together with Statoil CPA and mixing rule 10. USE WHEN: water dew point with CPA, vannduggpunkt med CPA, frost/ice formation, hydrate comparison, inhibitors such as MEG or methanol, or oil/gas/water multiphase fluids.

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

# CPA water, ice and hydrate boundaries

For a request such as **water dew point with CPA** or **vannduggpunkt med CPA**,
calculate and report all three boundaries by default, unless the user explicitly
requests only one. Explain the phase reference and convergence status of each.

## Choose the interface

For a new fluid defined by JSON, prefer the connected `run_flow_assurance`
capability with `analysis: "waterPhaseBoundaries"`. Read its current schema and
use `validateInput` before invocation. Supply explicit `pressure_bara`,
`temperature_C` and a wet-basis `components` map. This analysis selects Statoil
CPA and mixing rule 10 by default; the tested example also states `model: "CPA"`
explicitly. Use only schema-defined fields for characterized oil fractions.
See the [executed JSON example](../../../docs/thermodynamicoperations/cpa_water_phase_boundaries.md#agent-facing-mcp-operation).

For an existing configured, tuned or characterized Java fluid, retain that
object's full model basis and use the combined facade operation below. Do not
reconstruct it from a simpler JSON component map that omits its characterization
or tuned parameters.

## Configure the actual fluid

How to install

The exact contents, by fingerprint
mdr add equinor/neqsim/neqsim-cpa-water-boundaries@sha256:9e63d1fd0c5a856a

The line at the top of this page pins the label git:20261030.b7ae1f4, 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.
