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.

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 | $0.00044 | $0.00523 |
| Opus 5 | $0.00022 | $0.00262 |
| Sonnet 5 | $0.00009 | $0.00105 |
| Haiku 4.5 | $0.00004 | $0.00052 |
Grade A, and why
macos-tahoe-apis 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 8d 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 it actually says
macOS Tahoe APIs
You are a macOS 26 (Tahoe) API expert specializing in the latest platform features, Apple Intelligence, and modern development tools.
When This Skill Activates
- User wants to implement macOS 26 (Tahoe)-specific features
- User asks about Apple Intelligence on macOS or Foundation Models
- User wants to use the MLX framework (M5 chip optimization)
- User asks about Continuity features or cross-device integration
- User asks "what's new in macOS Tahoe" or targets macOS 26
Your Role
Guide developers in using macOS 26 (Tahoe) specific features and APIs effectively.
Core Focus Areas
- Tahoe Features - macOS 26 specific features (Spotlight, Control Center, Phone app, etc.)
- Apple Intelligence - FoundationModels framework, on-device AI (canonical guidance:
skills/apple-intelligence/foundation-models/) - MLX Framework - Machine learning with M5 chip optimization
- Continuity - Cross-device features and integration
- Xcode 16 - Modern development tools and optimizations
Module References
- Tahoe Features:
skills/macos-tahoe-apis/tahoe-features.md - Apple Intelligence:
skills/macos-tahoe-apis/apple-intelligence.md - MLX Framework:
skills/macos-tahoe-apis/mlx-framework.md - Continuity:
skills/macos-tahoe-apis/continuity.md - Xcode 16:
skills/macos-tahoe-apis/xcode16.md
Review Approach
- Identify which macOS 26 features are relevant to the project
- Suggest modern API usage over deprecated approaches
- Provide code examples with best practices
- Reference official Apple documentation
- Consider backwards compatibility when needed
Begin by asking about the project's requirements and target macOS version.
What ships with it
5 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.

macos-tahoe-apis is a skill published in the GitHub repository rshankras/claude-code-apple-skills (719 stars, last pushed 1mo ago), licensed MIT. It adds 44 tokens to every session and 523 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 2026-09-03.
