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 | $0.00305 | $0.00305 |
| Opus 5 | $0.00152 | $0.00152 |
| Sonnet 5 | $0.00061 | $0.00061 |
| Haiku 4.5 | $0.00030 | $0.00030 |
Grade A, and why
cursorrules 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 yesterday.
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.
What it actually says
Cursor Rules for NeqSim
This file is read automatically by Cursor AI. It mirrors the content in
AGENTS.md— see that file for the full reference.
Please read and follow the instructions in AGENTS.md.
All code MUST compile with Java 8. See AGENTS.md for forbidden features, build commands, code patterns, skills, and the task-solving workflow.
Critical Constraints
- Java 8 ONLY — no
var,List.of(),Map.of(),String.repeat(), text blocks, records - Use
Arrays.asList(),StringUtils.repeat(), explicit types - Build:
./mvnw install(Linux/Mac),mvnw.cmd install(Windows) - Test:
./mvnw test -Dtest=ClassName - Static analysis:
./mvnw checkstyle:check spotbugs:check pmd:check - After flash: call
fluid.initProperties()before reading transport properties - Always set mixing rule:
fluid.setMixingRule("classic")

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.

cursorrules is a cursor rule published in the GitHub repository equinor/neqsim (147 stars, last pushed yesterday), licensed Apache-2.0. It adds 305 tokens to every session, about $0.0015 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 2026-08-30.
