What it does

macOS Swiftpm is an agent skill from robinebers/openusage. Build, run, and test SwiftPM macOS packages and executables. Use when the repo is package-first or has no Xcode project.

Its SKILL.md is about 340 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Mobile, covering iOS development. It works with Swift, macOS and Xcode. The repository describes itself as: Burning through your subscriptions too fast? Paying for stuff you never use? Stop guessing. OpenUsage is free and open source. The licence is MIT.

When your agent uses it

  • The repo is package-first
  • Has no Xcode project

Example prompts

  • “/macos-swiftpm”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Inspect the package.
  2. Build with SwiftPM.
  3. Run the right product.
  4. Test narrowly.
  5. Summarize failures.

What it can do on your machine

Read from SKILL.md and the folder at commit 1c37176. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • swift

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

macOS Swiftpm loads about 344 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 172 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~34
When it runs · the whole SKILL.md, loaded when a task matches
~344

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SwiftPM for macOS

Quick Start

Use this skill when Package.swift is the primary entrypoint or when SwiftPM is the fastest path to a reproducible result.

Workflow

  1. Inspect the package.

    • Read Package.swift.
    • Identify executable, library, and test products.

  2. Build with SwiftPM.

    • Use swift build by default.
    • Use release mode only when the user explicitly needs it.

  3. Run the right product.

    • Use swift run <product> when an executable exists.
    • If multiple executables exist, explain the default choice.

  4. Test narrowly.

    • Use swift test.
    • Apply filters when a specific test target or case is known.

  5. Summarize failures.

    • Module/import resolution
    • Package graph or dependency issue
    • Linker failure
    • Runtime failure
    • Test regression

Guardrails

  • Prefer SwiftPM over Xcode when both exist and the package path is clearly simpler.
  • Do not assume an app bundle exists in a pure package workflow.
  • Explain when the package is library-only and therefore not directly runnable.

Output Expectations

Provide:

  • the package products you found
  • the command you ran
  • whether build, run, or test succeeded
  • the top blocker if not
