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 | $0.00037 | $0.00750 |
| Opus 5 | $0.00018 | $0.00375 |
| Sonnet 5 | $0.00007 | $0.00150 |
| Haiku 4.5 | $0.00004 | $0.00075 |
Grade A, and why
swift-package-pro 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Review Swift Package Manager libraries for sound public API design, clean module organization, and modern SPM features. Report only genuine problems - do not nitpick or invent issues.
Review process:
- Validate
Package.swiftstructure and target organization usingreferences/module-organization.md. - Check public API surface for correct access control using
references/public-api.md. - Verify
public importvsimportusage matchesInternalImportsByDefaultrules usingreferences/public-api.md. - Check resource handling for
.processvs.copycorrectness usingreferences/resources.md. - Validate semantic versioning,
@available, and deprecation patterns usingreferences/versioning.md. - Check inter-module dependency graph for cycles or unnecessary coupling using
references/module-organization.md.
If doing a partial review, load only the relevant reference files.
Core Instructions
- Target Swift 6.0 or later with
.swiftLanguageMode(.v6). - Prefer
InternalImportsByDefaultto make import visibility explicit and prevent accidental dependency re-export. - Public API is a contract — adding a
publicdeclaration is easy, removing it is a breaking change. Default tointernal. - Each module should have a single, well-defined responsibility. Flag modules that mix unrelated concerns.
- Avoid third-party dependencies in foundational utility packages — they become transitive burdens for every consumer.
- Use
path:parameters inPackage.swiftto define a per-module directory layout ({Module}/Sources/,{Module}/Tests/) — flatSources/andTests/directories don't scale.
Output Format
Organize findings by file. For each issue:
- State the file and relevant line(s).
- Name the rule being violated.
- Show a brief before/after code fix.
Skip files with no issues. End with a prioritized summary of the most impactful changes to make first.
Example output:
CoreUI/Sources/Spacing.swift
Line 7: Unnecessary public import — Foundation types do not appear in this file's public API.
What ships with it
4 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.
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.

swift-package-pro is a skill published in the GitHub repository kelvinkosbab/AppBootstrapAI (5 stars, last pushed 18d ago), licensed MIT. It adds 37 tokens to every session and 750 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
