What is apple-swift-package-bootstrap?

A setup tool for creating new Swift Package Manager projects, including their initial files and standard settings. Swift Package Manager is Apple’s system for building and sharing Swift code packages.

Use it to start a new Swift package for macOS, iOS, or multiple Apple platforms, choose a version profile, and customize the defaults used for future packages.

It avoids repeating project setup by applying the same platform, version, and structure defaults each time. It can also create project guidance files and validate the result immediately.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00045	$0.01270
Opus 5.5	$0.00018	$0.00508
Sonnet 5.5	$0.00009	$0.00254
Haiku 4.5	$0.00005	$0.00127

Security

Grade A, and why

apple-swift-package-bootstrap scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/bootstrap_swift_package.sh, scripts/customization_config.py, scripts/run_workflow.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Apple Swift Package Bootstrap

Purpose

Create a new Swift package repository with one top-level entry point. scripts/run_workflow.py is the runtime wrapper, and scripts/bootstrap_swift_package.sh remains the implementation core for scaffold creation and validation.

When To Use

Use this skill for new Swift package scaffolding.
Use this skill when the user wants consistent package defaults, AGENTS.md generation, and immediate validation.
Use this skill when the user wants to customize the documented bootstrap defaults for future runs.
Do not use this skill as the default path for normal Xcode app collaboration work.
Recommend apple-xcode-workflow when the user is working in an existing Xcode project or needs Apple-platform execution after bootstrap.
Recommend apple-dash-docsets when the user needs Dash docset search, install, or generation work.

Single-Path Workflow

Collect the required inputs:
- name
- type
- destination
- platform
- version_profile
- optional skip_validation
Normalize aliases exactly as scripts/bootstrap_swift_package.sh does:
- macos -> mac
- ios -> mobile
- both -> multiplatform
- latest -> latest-major
- minus-one -> current-minus-one
- minus-two -> current-minus-two
Run python3 scripts/run_workflow.py so documented defaults are loaded from customization state and normalized into one JSON contract.

Let the wrapper invoke the bundled script:

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>

Verify the generated repository:
- Package.swift
- .git
- AGENTS.md
- Tests/
- swift build and swift test unless --skip-validation was requested
Return one JSON execution summary with the created path, normalized options, and validation result.

What ships with it

11 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
