What it does
Hig Technologies is an agent skill from raintree-technology/hig-doctor. Apple HIG guidance for Apple technology integrations: Siri, Apple Pay, HealthKit, HomeKit, ARKit, machine learning, generative AI, iCloud, Sign in with Apple, SharePlay, CarPlay, Game Center, in-app purchase, NFC, Wallet, VoiceOver, Maps, Mac Catalyst, and more. Use when asked about: "Siri integration", "Apple Pay", "HealthKit", "HomeKit", "ARKit", "augmented reality", "machine learning", "generative AI", "iCloud sync", "Sign in with Apple", "SharePlay", "CarPlay", "in-app purchase", "NFC", "VoiceOver", "Maps"…
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 29 other files, including reference files (for example `references/airplay.md`, `references/always-on.md` and `references/apple-pay.md`).
It sits in Mobile, covering iOS development, Text to speech and voice and Machine learning. The repository describes itself as: Apple HIG reference and cross-framework UI audit tooling for agents. The licence is MIT.

What it can do on your machine
Read from SKILL.md and the folder at commit 3ec08f5. 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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
raintree.technology
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
Hig Technologies loads about 1.9k tokens when it runs, and up to ~26k if it reads all its reference files. Until then it costs about 213 tokens; SKILL.md has 672 words of instructions outside code blocks.
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.

Apple HIG: Technologies
Check for .claude/apple-design-context.md before asking questions. Use existing context and only ask for information not already covered.
Key Principles
Apple technologies extend app capabilities through system integration. Each technology has established user-facing patterns; deviating creates confusion and erodes trust.
Privacy and user control are paramount. Especially for health, payment, and identity technologies. Request only needed data, explain why, respect choices.
Siri: natural, predictable, recoverable. Clear conversational intent phrases that complete quickly and confirm results. Support App Shortcuts for proactive suggestions. Handle errors with clear fallbacks.
Payments: transparent and frictionless. Standard Apple Pay button styles. Never ask for card details when Apple Pay is available. Clearly describe what the user is buying, the price, and whether it's one-time or subscription.
Health data is deeply personal. Explain the health benefit before requesting access. CareKit tasks should be encouraging. ResearchKit consent flows must be thorough, readable, and respect autonomy.
HomeKit: simple and reliable. Immediate response when controlling devices. Clear device state. Graceful handling of connectivity issues.
AR: genuine value, not gimmicks. Use AR when spatial context improves understanding. Guide setup (surface, lighting, space). Provide clear exit back to standard interaction.
ML and generative AI: enhance without surprising. Smart suggestions, image recognition, text prediction. Clearly attribute AI-generated content. Controls to edit, regenerate, or dismiss. Let users correct mistakes.
Sign in with Apple as top option. Standard button styles. Respect email hiding preference. ID Verifier: guided flows, don't store sensitive data beyond what verification requires.
iCloud: invisible and reliable sync. Data appears on all devices without manual intervention. Handle conflicts gracefully. Never lose data.
SharePlay: real-time participation. Support multiple participants, show presence, handle latency. AirPlay: appropriate Now Playing metadata.
CarPlay: driver safety first. Minimize interaction complexity, large touch targets, no distracting content. Only permitted app types: audio, messaging, EV charging, navigation, parking, quick food ordering.
Accessibility is a baseline requirement. Every element has a meaningful VoiceOver label, trait, and action. Support Dynamic Type, Switch Control, and other assistive technologies. Test entirely with VoiceOver enabled.
