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 | $0.00690 | $0.00690 |
| Opus 5 | $0.00345 | $0.00345 |
| Sonnet 5 | $0.00138 | $0.00138 |
| Haiku 4.5 | $0.00069 | $0.00069 |
Grade A, and why
apple-platform-build-tools-claude-code-plugin CLAUDE.md 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 6d 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.

What This Repository Contains
This repository contains an Agent Skill and Subagent for Claude Code called building-apple-platform-products.
- Skill: Teaches Claude the xcrun ecosystem — xcodebuild, swift build, simctl, devicectl, code signing, profiling, distribution, and binary tools (reference documentation)
- Agent: Executes build and device management commands autonomously, discovering schemes and destinations as needed
Repository Structure

└── building-apple-platform-products/
├── SKILL.md # Entry point with YAML frontmatter
└── references/ # Detailed documentation loaded on-demand

└── builder.md # Autonomous build executor
Skill components:
- SKILL.md: Quick reference tables and links to reference files
- references/: Progressive disclosure—Claude loads these only when needed
Agent: Discovers project structure, constructs correct commands, executes autonomously
Reference files cover: xcrun tool resolution, xcodebuild, swift build, simctl (simulator management), devicectl (physical devices), code signing, profiling/results (xctrace, xcresulttool), distribution (notarization, App Store upload), and binary tools (lipo, otool, dsymutil, atos, plutil, docc)
Key Design Principles
- Reference manual style: Use tables and clear categories, not decision trees
- Standalone Swift packages only:
swift build/swift testdo NOT work for Swift Package Manager submodules in Xcode projects—must usexcodebuildwith the appropriate scheme - Simulator name volatility: Device names change with Xcode releases; always document
xcrun simctl list devices available - JSON output for scripting: Both simctl and devicectl offer JSON output; always prefer structured output over parsing human-readable text
- devicectl requires iOS 17+: Older devices are invisible to devicectl; document this constraint prominently
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.
