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.

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 | $0.00114 | $0.04283 |
| Opus 5.5 | $0.00046 | $0.01713 |
| Sonnet 5.5 | $0.00023 | $0.00857 |
| Haiku 4.5 | $0.00011 | $0.00428 |
Grade A, and why
neqsim-acid-gas-treating 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 12d ago.
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.

Acid-Gas Treating with NeqSim
When to use this
- Build a screening acid-gas absorber/regenerator using the
SimpleAmine*equipment. - Evaluate CO2/H2S phase equilibrium with Kent-Eisenberg or Desmukh-Mather systems.
- Compare packed-column transfer calculations, equilibrium-stage columns, and shortcut absorbers.
- Screen an H2S scavenger injection rate or a membrane/PSA component-removal alternative.
- Inspect an adsorption bed, PSA cascade, or cyclic adsorption controller.
- Verify component balances, acid-gas loading, H2 purity/recovery, and absorber/regenerator outputs.
The equipment names do not all imply the same fidelity. SimpleAmineAbsorber applies configured
removal efficiencies and transfers removed acid gas to a cloned solvent stream; it is not a reactive
amine equilibrium or mass-transfer solver. SimpleAmineRegenerator uses simplified loading and duty
balances. RateBasedAbsorber has Onda and Billet-Schultes transfer correlations, but requires
credible packing, fluid, and calibration inputs. MembraneSeparator and PressureSwingAdsorptionBed
are simplified separation models. Use AbsorptionColumn/StrippingColumn or reactive thermo systems
when their different physical basis fits the question, and state remaining validation gaps.

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-acid-gas-treating is a skill published in the GitHub repository equinor/neqsim (156 stars, last pushed today), licensed Apache-2.0. It adds 114 tokens to every session and 4,283 once invoked, about $0.0005 per session on Opus 5.5. 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 2026-10-05.
