Individual skill
property-patterns
Diagnose and fix concrete MSBuild property defects in projects and existing shared-file hierarchies. USE FOR: conditions, defaults, append versus overwrite, last-write-wins values, OS/TFM checks, portable paths, normalization, and reviews centered on those property defects. Property defects in Directory.Build.* remain in scope, including overwritten values across parent/child imports and conditions that run before TargetFramework is set, even when the fix changes import order or moves a property group to .targets. DO NOT USE FOR: placement-only or import-only requests with no concrete property defect, such as discovering shared files or choosing which file owns a target or customization (use directory-build-organization); item operations; target structure; broad reviews without a concrete property defect; non-MSBuild work.

# MSBuild Property Patterns
Canonical property definition and manipulation patterns from the MSBuild repository.
## Conditional Defaults — The Foundational Pattern
Set a property **only if not already set**, allowing callers to override:
```xml
<PropertyGroup>
<Configuration Condition="'$(Configuration)' == ''">Debug</Configuration>
<Platform Condition="'$(Platform)' == ''">AnyCPU</Platform>
<BuildInParallel Condition="'$(BuildInParallel)' == ''">true</BuildInParallel>
</PropertyGroup>
