Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00260 | $0.19221 |
| Opus 5 | $0.00130 | $0.09610 |
| Sonnet 5 | $0.00052 | $0.03844 |
| Haiku 4.5 | $0.00026 | $0.01922 |
Grade A, and why
neqsim-flow-assurance scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 1,386 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Flow Assurance Analysis with NeqSim
Consolidated guide for all flow assurance threats — hydrate, wax, asphaltene, corrosion, hydraulics, water/liquid hammer screening, slugging, and thermal management — with NeqSim code patterns.
When to Use This Skill
- Hydrate formation temperature/pressure prediction
- Hydrate inhibitor dosing (MEG, methanol, ethanol)
- Wax appearance temperature (WAT) and wax deposition risk
- Asphaltene stability screening (de Boer, CII)
- CO2 and H2S corrosion rate estimation
- Elemental sulfur (S8) deposition risk at pressure/temperature letdown (compressor inlets, control/letdown valves, dry-gas seals, filters)
- Pipeline pressure drop and temperature profile
- DNV-RP-F109 vertical and lateral on-bottom stability screening
- Water hammer/liquid hammer screening for fast valve closure, pump trip, or check-valve slam
- Multiphase flow pattern prediction (slug, annular, stratified)
- Thermal insulation sizing for subsea pipelines
- Arrival temperature and cooldown calculations

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

neqsim-flow-assurance is a skill published in the GitHub repository equinor/neqsim (151 stars, last pushed today), licensed Apache-2.0. It adds 260 tokens to every session and 19,221 once invoked, about $0.0013 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
