Cross Platform Build Expert

This one handles the messy parts of building software across Windows, macOS, and Linux. It enforces a mandatory reading protocol that makes you check reference files before touching platform-specific configs, which is actually smart since cross-platform builds are where things usually break. The skill covers build matrices, conditional compilation, code signing, and macOS notarization. It failed the Gen Agent Trust Hub security audit but passed Socket and Snyk, so read through the implementation before using it in production. Good fit if you're tired of debugging why your build works on Mac but explodes on Windows.

0. Mandatory Reading Protocol

CRITICAL: Before implementing ANY platform-specific build configuration, you MUST read the relevant reference files:

Trigger Conditions for Reference Files

Read references/advanced-patterns.md WHEN:

Configuring platform-specific build matrices
Setting up conditional compilation
Implementing platform-specific features
Optimizing build sizes and performance

Read references/security-examples.md WHEN:

Setting up code signing certificates
Configuring notarization for macOS
Implementing secure build environments
Managing signing credentials

1. Overview

Risk Level: MEDIUM

Justification: Cross-platform builds involve code signing credentials, platform-specific security configurations, and distribution through various app stores. Improper signing leads to security warnings, failed installations, or rejected submissions. Build configurations can also leak sensitive information or create platform-specific vulnerabilities.
