  • Confirm the extracted package contains the expected setup assets.

Install with your agent

Agent handoff

Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.

  1. Download the package from Yavira.
  2. Extract it into a folder your agent can access.
  3. Paste one of the prompts below and point your agent at the extracted folder.
New install

I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.

Upgrade existing

I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

HealthKit Sync CLI

Securely sync Apple HealthKit data from iPhone to Mac over local network using mTLS.

When to Use This Skill

User asks about syncing health data from iPhone User mentions healthsync CLI commands User wants to fetch steps, heart rate, sleep, or workout data User needs to pair a Mac with an iOS device User asks about the iOS Health Sync project architecture User mentions certificate pinning or mTLS patterns

Pairing Flow (First Time)

# 1. Discover devices on local network healthsync discover # 2. On iOS app: tap "Share" to generate QR code, then "Copy" # 3. Scan QR from clipboard (Universal Clipboard) healthsync scan # Alternative: scan from image file healthsync scan --file ~/Desktop/qr.png

Fetching Health Data

# Check connection status healthsync status # List enabled data types healthsync types # Fetch data as CSV (default) healthsync fetch --start 2026-01-01T00:00:00Z --end 2026-12-31T23:59:59Z --types steps # Fetch multiple types as JSON healthsync fetch --start 2026-01-01T00:00:00Z --end 2026-12-31T23:59:59Z \ --types steps,heartRate,sleepAnalysis --format json | jq # Pipe to file healthsync fetch --start 2026-01-01T00:00:00Z --end 2026-12-31T23:59:59Z \ --types steps > steps.csv

Available Health Data Types

Activity: steps, distanceWalkingRunning, distanceCycling, activeEnergyBurned, basalEnergyBurned, exerciseTime, standHours, flightsClimbed, workouts Heart: heartRate, restingHeartRate, walkingHeartRateAverage, heartRateVariability Vitals: bloodPressureSystolic, bloodPressureDiastolic, bloodOxygen, respiratoryRate, bodyTemperature, vo2Max Sleep: sleepAnalysis, sleepInBed, sleepAsleep, sleepAwake, sleepREM, sleepCore, sleepDeep Body: weight, height, bodyMassIndex, bodyFatPercentage, leanBodyMass

Configuration

Config stored at ~/.healthsync/config.json (permissions: 0600): { "host": "192.168.1.x", "port": 8443, "fingerprint": "sha256-certificate-fingerprint" } Token stored in macOS Keychain under service org.mvneves.healthsync.cli.

Certificate Pinning

The CLI validates server certificates by SHA256 fingerprint (TOFU model): First pairing stores fingerprint from QR code Subsequent connections verify fingerprint matches Mismatch = connection rejected (MITM protection)

Local Network Only

Host validation restricts connections to: localhost, *.local domains Private IPv4: 192.168.*, 10.*, 172.16-31.* IPv6 loopback: ::1, link-local: fe80::

Keychain Storage

Tokens never stored in config file - always in Keychain with: kSecAttrAccessibleWhenUnlocked protection class Service: org.mvneves.healthsync.cli Account: token-{host}

Troubleshooting

"No devices found": Ensure iOS app is running with sharing enabled Both devices must be on same Wi-Fi network Check firewall isn't blocking mDNS (port 5353) "Pairing code expired": Generate new QR code on iOS app (codes expire in 5 minutes) "Certificate mismatch": Delete ~/.healthsync/config.json and re-pair Server certificate may have been regenerated "Connection refused": iOS app server may not be running Run healthsync status --dry-run to test without connecting
