# macOS Runtime Debugger Create one project-local `script/build_and_run.sh` and use it as the default build/run/debug path. In Codex app sessions, optionally wire the same script to `.codex/environments/environment.toml`. ## Workflow 1. Discover project shape: ```bash git rev-parse --is-inside-work-tree find . -name '*.xcworkspace' -o -name '*.xcodeproj' -o -name 'Package.swift' ``` If no git repo exists and a host tool needs one, run `git init` at the workspace root, never inside a nested repo. 2. Resolve runnable target/process: - Xcode: list schemes and prefer the app-producing scheme unless named. - SwiftPM CLI: run the executable. - SwiftPM AppKit/SwiftUI GUI: stage a project-local `.app` bundle and launch with `/usr/bin/open -n`; do not run as a raw executable. 3. Create/update executable `script/build_and_run.sh`. It should kill existing process, build, launch, and support optional `--debug`, `--logs`, `--telemetry`, and `--verify`. 4. Use `references/run-button-bootstrap.md` as the canonical script/environment shape; do not duplicate a second full snippet. 5. In Codex app sessions, create/update `.codex/environments/environment.toml` only after the script exists; point the Run action at `./script/build_and_run.sh`. 6. Run through the script: ```bash ./script/build_and_run.sh ./script/build_and_run.sh --debug ./script/build_and_run.sh --logs ./script/build_and_run.sh --telemetry ./script/build_and_run.sh --verify ``` 7.
