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 | $0.00103 | $0.03081 |
| Opus 5.5 | $0.00041 | $0.01232 |
| Sonnet 5.5 | $0.00021 | $0.00616 |
| Haiku 4.5 | $0.00010 | $0.00308 |
Grade A, and why
neqsim-produced-water-and-solids-separation 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.

Produced Water and Solids Separation
When to use this
- Screen a produced-water treatment train, oil-in-water outlet, or discharge volume.
- Size/check hydrocyclone liners, differential pressure, turndown, or droplet response.
- Represent gas flotation, solids splitting, centrifuge dewatering, filter pressure drop, or sulfur removal.
- Evaluate crystallization, liquid-liquid extraction, cryogenic separation, or end-flash where those unit models fit the stated process.
- Evaluate gas/liquid mass transfer over a pipeline with the evaporation/dissolution studies.
- Estimate dissolved-gas release from produced water with the degassing utility.
This skill owns separation and treatment equipment. It does not own chemical selection or dose optimization. Route demulsifier dose-response, lag, compatibility, and recommended dose to neqsim-production-chemistry; reuse its result rather than repeating that model here. Build ion composition and scale chemistry with neqsim-electrolyte-systems.

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-produced-water-and-solids-separation is a skill published in the GitHub repository equinor/neqsim (156 stars, last pushed today), licensed Apache-2.0. It adds 103 tokens to every session and 3,081 once invoked, about $0.0004 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.
