whoop

whoop is a skill for Claude Code, Codex from Demerzels-lab/elsamultiskillagent. It costs 44 tokens per session (2,391 once invoked), scanned A, original, MIT.

A connector for retrieving personal health data from WHOOP, including sleep, recovery, strain, and workouts. WHOOP is a wearable service that records these measurements.

In plain words
What is it for?
Use it to fetch recovery scores, HRV, resting heart rate, sleep stages, strain, calories, and workout details, or import historical records.
Why use it?
It lets an agent use your WHOOP measurements without requiring you to copy daily health data manually.

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

whoop 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 9d ago.

The scan reads SKILL.md. This mod also ships 10 executable files (src/auth.js, src/import-historical.js, src/recovery.js, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

WHOOP Central

Access sleep, recovery, strain, and workout data from WHOOP via the v2 API.

Quick Commands

# 1) One-time setup (writes ~/.clawdbot/whoop/credentials.json)
node src/setup.js

# 2) Recommended: Get tokens via Postman (see Auth section), then verify
node src/verify.js
node src/verify.js --refresh

# Prompt-friendly snapshot (includes last workout)
node src/today.js

# Daily summary (all metrics)
node src/summary.js

# Individual metrics
node src/recovery.js
node src/sleep.js
node src/strain.js
node src/workouts.js

# Bulk import to ~/clawd/health/logs/whoop/*
node src/import-historical.js

Data Available

Metric Data Points
Recovery Score (0-100%), HRV, resting HR, SpO2, skin temp
Sleep Duration, stages (REM/deep/light), efficiency, performance
Strain Daily strain (0-21), calories, avg/max HR
Workouts Activity type, duration, strain, calories, HR

Recovery Score Guide

  • 💚 67-100% Green - Ready to perform
  • 💛 34-66% Yellow - Moderate readiness
  • ❤️ 0-33% Red - Focus on recovery

Setup

0. Requirements

  • Node.js 18+ (this repo uses ESM)
  • openssl (only needed for the optional auth.js flow when using https://localhost; Postman auth does not need it)

1. Create WHOOP Developer App

  1. Go to https://developer.whoop.com/
  2. Sign in with your WHOOP account
  3. Create a new App
  4. Add these Redirect URIs (exact match; no extra trailing slashes):
    • Postman browser callback (recommended auth path):
      https://oauth.pstmn.io/v1/browser-callback
      
    • Optional local callback (only used by auth.js):
      https://localhost:3000/callback
      
    You can keep both registered at the same time.
  5. Copy the Client ID and Client Secret

Team note: this skill does not ship any client credentials. Each user can create their own WHOOP app, or (if you trust each other) a team can share one app's client_id/client_secret and let multiple WHOOP accounts authorize it.

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.

whoop is a skill published in the GitHub repository Demerzels-lab/elsamultiskillagent (10 stars, last pushed 4mo ago), licensed MIT. It adds 44 tokens to every session and 2,391 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings.
