Build / Run / Debug

Quick Start

Use this skill to set up one project-local script/build_and_run.sh entrypoint, wire .codex/environments/environment.toml so the Codex app shows a Run button, then use that script as the default build/run path.

Prefer shell-first workflows:

• ./script/build_and_run.sh as the single kill + build + run entrypoint once it exists
• xcodebuild for Xcode workspaces or projects
• swift build plus raw executable launch inside that script for true SwiftPM command-line tools
• swift build plus project-local .app bundle staging and /usr/bin/open -n launch for SwiftPM AppKit/SwiftUI GUI apps
• optional script flags for lldb, log stream, telemetry verification, or post-launch process checks

Do not assume simulators, touch interaction, or mobile-specific tooling.
