Fastlane/Mobile CI-CD Skill

Overview

This skill provides comprehensive capabilities for mobile CI/CD automation using Fastlane. It enables automated builds, testing, code signing, beta distribution, and app store deployments for both iOS and Android platforms.

Allowed Tools

• bash - Execute Fastlane commands, Ruby, and bundler
• read - Analyze Fastfile, Appfile, and configuration files
• write - Generate Fastlane configurations and lanes
• edit - Update existing Fastlane configurations
• glob - Search for Fastlane and CI configuration files
• grep - Search for patterns in CI/CD configurations
