unity-version-split — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited unity-version-split (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Split a C# source file into two variants: one for Unity 6.5+ (UNITY_6000_5_OR_NEWER) and one for older versions (pre-Unity 6.5).
Unity 6.5 introduced breaking changes including:
EntityId replaces int for instance IDs (GetEntityId() replaces GetInstanceID())EditorUtility.EntityIdToObject(EntityId) replaces EditorUtility.InstanceIDToObject(int)EntityId <-> int conversions are marked [Obsolete(..., true)] (compile error)When a file needs different code for these Unity versions, split it into two files following the project convention.
| File | Purpose | Preprocessor Guard |
|---|---|---|
FileName.cs | Unity 6.5+ (newer version) | #if UNITY_6000_5_OR_NEWER |
FileName.pre-Unity.6.5.cs | Pre-Unity 6.5 (older version) | #if !UNITY_6000_5_OR_NEWER |
For files that also have Editor/Runtime variants, combine the guards:
| File | Guard |
|---|---|
FileName.Editor.cs | #if UNITY_EDITOR && UNITY_6000_5_OR_NEWER |
FileName.Editor.pre-Unity.6.5.cs | #if UNITY_EDITOR && !UNITY_6000_5_OR_NEWER |
FileName.Runtime.cs | #if !UNITY_EDITOR && UNITY_6000_5_OR_NEWER |
FileName.Runtime.pre-Unity.6.5.cs | #if !UNITY_EDITOR && !UNITY_6000_5_OR_NEWER |
Read $ARGUMENTS (the target file path). Identify which parts need version-specific code.
Common differences between Unity 6.5+ and pre-6.5:
| Unity 6.5+ | Pre-Unity 6.5 |
|---|---|
EntityId | int |
EntityId.None | 0 |
go.GetEntityId() | go.GetInstanceID() |
EditorUtility.EntityIdToObject(entityId) | EditorUtility.InstanceIDToObject(instanceID) |
ObjectRef.InstanceID is EntityId | ObjectRef.InstanceID is int? |

#nullable enable#endif matching the opening #ifRun assets-refresh tool to let Unity generate .meta files and recompile.
IMPORTANT: Do NOT manually create `.meta` files. Unity auto-generates them after assets-refresh or any AssetDatabase.Refresh() call.
Check for compilation errors using console-get-logs tool.
Given GameObjectUtils.Runtime.cs with #if !UNITY_EDITOR that uses both EntityId and int with #if UNITY_6000_5_OR_NEWER inside:
Before (single file with nested #if):
#if !UNITY_EDITOR
// ...
#if UNITY_6000_5_OR_NEWER
public static GameObject? FindByInstanceID(EntityId instanceID) { ... }
#else
public static GameObject? FindByInstanceID(int instanceID) { ... }
#endif
#endifAfter (two clean files):
GameObjectUtils.Runtime.cs:
#if !UNITY_EDITOR && UNITY_6000_5_OR_NEWER
// ...
public static GameObject? FindByInstanceID(EntityId instanceID) { ... }
#endifGameObjectUtils.Runtime.pre-Unity.6.5.cs:
