skill

skill is a skill for Claude Code, Codex from sprausliu/healthclaw. It costs 0 tokens per session (2,004 once invoked), scanned A, original, MIT.

A connector that sends iPhone and Apple Watch health records to an OpenClaw agent through a local webhook server. The records can include heart rate, heart-rate variability, sleep, steps, and workouts.

In plain words
What is it for?
Use it to sync individual or batches of health records, maintain an append-only log, remove duplicates, calculate recovery information, examine trends, and set alerts.
Why use it?
It puts health data in a form the agent can query and analyze instead of leaving it only inside Apple Health.

Token cost

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.

Security

Grade A, and why

skill scanned grade A with 1 finding 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 10d 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.

HealthClaw Skill

Connect your iPhone/Apple Watch health data to OpenClaw for AI-powered analysis.

HealthClaw streams Apple Health data (heart rate, HRV, sleep, steps, workouts) to your OpenClaw agent via a local webhook server. Once connected, your agent can calculate recovery scores, detect health anomalies, answer questions about your health trends, and proactively alert you when something looks off.


How It Works

iPhone / Apple Watch
        ↓  (HealthKit → background sync)
  iOS App (HealthClaw)
        ↓  (HTTPS POST)
  Webhook Server  ←  npx healthclaw-webhook-server
        ↓
  health-data.jsonl  (append-only log)
        ↓
  OpenClaw Agent  (queries, crons, alerts)

Key concepts

Concept Description
Pairing One-time setup: server issues a time-limited token (2 min), iOS app scans or opens the deep-link, exchanges it for a permanent API token stored securely on the server
Data sync iOS app POSTs individual records to /api/health-sync or bulk batches to /api/health-sync/batch. Each record contains a type, value, unit, startDate, endDate, and optional metadata
Deduplication Every record gets a deterministic ID from (type, startDate, endDate, value). The server keeps a SQLite dedupe index — re-syncing the same data is always safe, duplicates are silently dropped
Storage All data is appended to health-data.jsonl in a platform-appropriate user directory (~/Library/Application Support/healthclaw-webhook on macOS)

Setup

1. Start the webhook server

npx healthclaw-webhook-server

The server starts on port 3000 by default. Keep it running (consider a LaunchAgent / systemd service for persistence).

Optional environment variables:

PORT=3000                         # Server port
HEALTHCLAW_DATA_DIR=~/custom/path # Override data directory
ADMIN_TOKEN=your-secret           # Protect admin endpoints

2. Expose to the internet (for iOS sync)

Changes

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.

skill is a skill published in the GitHub repository sprausliu/healthclaw (5 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,004 tokens. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
