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: 1 finding, 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 | $0.00129 | $0.05435 |
| Opus 5.5 | $0.00052 | $0.02174 |
| Sonnet 5.5 | $0.00026 | $0.01087 |
| Haiku 4.5 | $0.00013 | $0.00543 |
Grade A, and why
neqsim-hydrogen-production 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 20d 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.
How it starts

Hydrogen Production with NeqSim
Guide for modeling hydrogen production routes — steam methane reforming (SMR),
autothermal reforming (ATR), partial oxidation (POX), PSA purification (blue
H2), and water electrolysis (green/pink H2). Companion to
neqsim-ccs-hydrogen (transport/storage/blending) and neqsim-reaction-engineering
(reformer kinetics).
When to Use This Skill
- SMR fired reformer, ATR, and POX plant flowsheets with WGS + PSA
- Oxygen-to-carbon and steam-to-carbon envelope screening
- Reformer furnace heat-balance and tube-wall checks
- POX/ATR quench, refractory, soot-risk, and H2/CO screening
- PSA bed sizing and purity/recovery analysis
- Electrolyzer technology selection (PEM vs Alkaline vs SOEC vs AEM)
- Stack voltage modeling from current density (I-V curves)
- Specific energy consumption (kWh/kg H₂)
- Hydrogen plant CAPEX estimation
- Cryogenic para/ortho H₂ conversion screening
- Catalyst activity decay for SMR/WGS/ammonia cracking studies
- Blue vs green H₂ techno-economic comparison

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-hydrogen-production is a skill published in the GitHub repository equinor/neqsim (156 stars, last pushed today), licensed Apache-2.0. It adds 129 tokens to every session and 5,435 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 2026-09-03.
