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 high
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 →
- high Tool Misuse · line 65 Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.
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 | $0.00066 | $0.01312 |
| Opus 5.5 | $0.00026 | $0.00525 |
| Sonnet 5.5 | $0.00013 | $0.00262 |
| Haiku 4.5 | $0.00007 | $0.00131 |
Grade A, and why
neqsim-java8-rules 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 1mo 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
The opening of the file, as written. The whole thing — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Java 8 Compatibility Rules for NeqSim
All NeqSim Java code — including test classes in src/test/java/ — MUST compile with Java 8. The CI build will FAIL if you use Java 9+ features.
Forbidden Java 9+ Features
| Forbidden | Java 8 Alternative |
|---|---|
var x = ... |
Explicit type: String x = ..., Map<String, Object> map = ... |
List.of(a, b) |
Arrays.asList(a, b) or Collections.singletonList(a) |
Set.of(a, b) |
new HashSet<>(Arrays.asList(a, b)) |
Map.of(k, v) |
Collections.singletonMap(k, v) or new HashMap<>() |
"str".repeat(n) |
StringUtils.repeat("str", n) (Apache Commons) |
str.isBlank() |
str.trim().isEmpty() |
str.strip() |
str.trim() |
str.lines() |
str.split("\\R") or BufferedReader |
Optional.isEmpty() |
!optional.isPresent() |
Text blocks """...""" |
Regular strings with \n |
| Records | Regular class with fields, constructor, getters |
Pattern matching instanceof |
Traditional instanceof + cast |
Stream.toList() |
.collect(Collectors.toList()) |
Common var Replacements
// WRONG (Java 10+):
var map = someMethod.toMap();
var list = getItems();
var result = calculate();
// CORRECT (Java 8):
Map<String, Object> map = someMethod.toMap();
List<String> list = getItems();
CalculationResult result = calculate();
Required Import for String Repeat
import org.apache.commons.lang3.StringUtils;
// Usage: StringUtils.repeat("=", 70)
Code Formatting (Spotless) — MANDATORY
AI-generated Java is NOT auto-formatted. After creating or editing ANY .java
file, reformat it before committing — do not rely on local pre-commit hooks
being installed:
./mvnw spotless:apply # reformats Java to the project style (Eclipse profile)
./mvnw spotless:check # verifies formatting — this is what CI runs
- Formatter profile:
.config/neqsim_formatter.xml(configured inpom.xml), applied tosrc/main/javaandsrc/test/java. - CI runs
./mvnw spotless:checkand FAILS the build on any unformatted file. - Run
spotless:apply, thengit addthe reformatted files, then commit. - NEVER bypass the gate with
git commit --no-verify.
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.
- 1mo ago First seen · 134 lines · 66 tokens per session scan A 1201c146f7ee
neqsim-java8-rules is a skill published in the GitHub repository equinor/neqsim (156 stars, last pushed today), licensed Apache-2.0. It adds 66 tokens to every session and 1,312 once invoked, about $0.0003 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.
