What it does

Expo Healthkit is an agent skill from appeeky/expo-healthkit. Use expo-healthkit, the identifier-based HealthKit (iOS) and Health Connect (Android) SDK for Expo/React Native. Triggers: expo-healthkit, @appeeky/expo-healthkit, HealthKit, Health Connect, Apple Health, Google Health Connect, HKQuantityType, queryQuantitySamples, queryStatistics, activity rings, ECG, audiogram, clinical records, workout GPS route, correlations, blood pressure, heartbeat series, requestAuthorization, NSHealthShareUsageDescription, development builds for HealthKit.

Its SKILL.md is about 2.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `background-delivery.md`, `examples.md` and `reference.md`).

It sits in Mobile, covering Cross-platform mobile apps. It works with Expo, Android, iOS and React Native. The repository describes itself as: Apple HealthKit and Android Health Connect for Expo and React Native, built on the Expo Modules API. One JavaScript API on both platforms.

When your agent uses it

  • Tasks that involve Cross-platform mobile apps

Example prompts

  • “/expo-healthkit”

Requirements

  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit 2843282. 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

    Shell commands in SKILL.md call:

    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

    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

Expo Healthkit loads about 2.3k tokens when it runs. Until then it costs about 125 tokens; SKILL.md has 872 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~125
When it runs · the whole SKILL.md, loaded when a task matches
~2.3k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 872 words (~2,335 tokens).

“Generic HealthKit-style SDK for iOS and Android. One query/save API plus Apple identifier strings — not getStepCount() / getHeartRateSamples(). iOS uses HealthKit; Android maps the same identifiers onto Health Connect. App code should not Platform.OS fork mapped types.”
