Bootstrap Swift Package

Overview

Create a new Swift package quickly with repeatable defaults. Prefer the bundled script for deterministic setup.

Workflow

1. Confirm package intent.

• Ask for package name, type (library, executable, or tool), destination path, platform preset (mac, mobile, multiplatform), and version profile (latest-major, current-minus-one, current-minus-two).
• Accept aliases: macos for mac, ios for mobile, both for multiplatform, and latest/minus-one/minus-two for version profiles.

2. Create the package.

• Preferred: run scripts/bootstrap_swift_package.sh --name <Name> --type <library|executable|tool> --destination <dir> --platform <mac|macos|mobile|ios|multiplatform|both> --version-profile <latest-major|current-minus-one|current-minus-two|latest|minus-one|minus-two>.
• Fallback: run swift package init --name <Name> --type <library|executable|tool> manually inside the target directory, patch Package.swift platforms, copy assets/AGENTS.md to repo root as AGENTS.md, then run git init.

3. Validate bootstrap output.

• Verify Package.swift exists.
• Verify .git exists.
• Verify AGENTS.md exists.
• Verify Tests/ exists.
• Run swift build and swift test in the package root.

4. Report result.

• Summarize created path, package type, platform preset, version profile, build/test status, and immediate next steps.

Defaults

• Use library unless the user clearly asks for executable or tool.
• Use multiplatform unless the user clearly wants only mac or mobile.
• Use current-minus-one as the default version profile.
• Keep generated structure minimal; do not add extra frameworks unless requested.
• Always initialize git.
• Always include AGENTS.md with repository expectations for working with Swift Package Manager and Swift packages.

Automation Prompting

• Codex App automation fit: Guarded. Prefer event-driven or explicit scaffold requests over frequent recurring schedules.
• Codex CLI automation fit: Strong. Use deterministic codex exec prompts with explicit placeholders and strict scope.
• Use references/automation-prompts.md for ready-to-use Codex App and Codex CLI templates.
• Keep schedule and workspace configuration outside the prompt body for App automations.

Troubleshooting

• If swift is missing, stop and ask the user to install Xcode command line tools or Swift toolchain.
• If git is missing, stop and ask the user to install git or Xcode command line tools.
• If assets/AGENTS.md is missing, stop and restore the template before bootstrapping packages.
• If destination exists and is non-empty (excluding ignorable macOS metadata like .DS_Store), do not overwrite; ask for a new destination or explicit cleanup instructions.
• If validation fails in constrained environments, rerun with --skip-validation and report that checks were skipped.
