Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00034 | $0.00319 |
| Opus 5 | $0.00017 | $0.00160 |
| Sonnet 5 | $0.00007 | $0.00064 |
| Haiku 4.5 | $0.00003 | $0.00032 |
Grade A, and why
swiftpm-macos 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 10d ago.
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.
This is a copy
97% identical to macos-swiftpm — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
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
-
Inspect the package.
- Read
Package.swift. - Identify executable, library, and test products.
- Read
-
Build with SwiftPM.
- Use
swift buildby default. - Use release mode only when the user explicitly needs it.
- Use
-
Run the right product.
- Use
swift run <product>when an executable exists. - If multiple executables exist, explain the default choice.
- Use
-
Test narrowly.
- Use
swift test. - Apply filters when a specific test target or case is known.
- Use
-
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
What ships with it
1 file 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.
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.

swiftpm-macos is a skill published in the GitHub repository fanfan-de/anybox (57 stars, last pushed 27d ago), licensed MIT. It adds 34 tokens to every session and 319 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 97% identical to macos-swiftpm, differing in 2 lines, and is treated as a copy.
