neqsim-java8-rules from equinor/neqsim is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add equinor/neqsim/neqsim-java8-rules@git:20260620.2d08b62Pins git:20260620.2d08b62 in mdr.lock. Pin the fingerprint instead.

Java 8 compatibility rules for NeqSim. USE WHEN: writing or reviewing any Java code for NeqSim, including tests. Covers forbidden Java 9+ features, replacement patterns, API verification, and JavaDoc requirements. All NeqSim Java code MUST compile with Java 8.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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
```java
// WRONG (Java 10+):
var map = someMethod.toMap();

How to install
mdr add equinor/neqsim/neqsim-java8-rules@sha256:1201c146f7ee453cThe line at the top of this page pins the label git:20260620.2d08b62, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
