Blood

What This Skill Does

Blood is a robust, privacy-focused command-line health and wellness tracking tool designed for the OpenClaw ecosystem. It serves as a local personal database for health metrics, allowing users to log, monitor, and analyze vital signs such as blood pressure, glucose levels, and other custom health metrics. By keeping all data stored strictly on the local machine within ~/.local/share/blood/, it ensures total privacy, as no medical information is ever transmitted to external servers.

Beyond basic logging, the tool offers advanced analytical capabilities. Users can generate trend charts, view weekly or monthly summaries, establish personal health goals, and track streaks or milestones. The tool is highly interoperable, supporting data exports in JSON, CSV, or plain text formats, making it easy to share health trends with medical professionals or integrate the data into other analytical applications. It is an ideal solution for users who want to maintain comprehensive personal medical records without relying on cloud-based proprietary health services.

Installation

You can install this skill directly into your OpenClaw environment by running the following command: clawhub install openclaw/skills/skills/bytesagain/blood

Once installed, you can verify the status and health of the data directory by running blood status to ensure everything is configured correctly.

Use Cases

• Routine Health Logging: Keep a daily log of blood pressure or glucose readings to build a long-term profile for your doctor.
• Trend Analysis: Monitor how lifestyle changes affect your health over time using the blood trend and blood chart features.
• Medical Data Portability: Export your entire health history into a CSV file to provide to your physician during an annual physical.
• Milestone Tracking: Set goals for weight or health metrics and use the blood streak and blood milestone features to maintain motivation.
• Privacy-First Data Management: Store highly sensitive personal health metrics locally without risk of cloud-based data breaches.

Example Prompts

1. "Blood, log my morning blood pressure reading: 120 over 80 at 8:00 AM."
2. "Show me a summary of my health trends for the last month using the Blood skill."
3. "Export all my blood glucose logs into a CSV file so I can email them to my endocrinologist."

Tips & Limitations

• Offline Reliability: The primary strength of Blood is its offline-first architecture. Because the data is stored in a local directory, it remains accessible even without an active internet connection.
• Backup Regularly: Although the data is stored locally, it is the user's responsibility to perform backups. Utilize the blood export command regularly to ensure your historical health data is saved to a secure secondary location or cloud storage.
• Security: Since the data is stored in clear text or standard formats within your home directory, ensure your user profile is protected by strong OS-level encryption or authentication.
• Command Scope: The tool works best when used consistently. Use the blood help command to see the full list of available metrics and flags to ensure your entries are categorized correctly for later reporting.
