/install healthcheck
Description
Track water and sleep with JSON file storage
Usage Guidance
Install only if you are comfortable with the agent running local Node.js commands and storing water and sleep history in `{baseDir}/health-data.json`. Ensure cup counts are treated as numbers, not copied as arbitrary text into the command.
Capability Analysis
Type: OpenClaw Skill
Name: healthcheck
Version: 1.0.2
The skill is classified as suspicious due to the potential for prompt/command injection. The `SKILL.md` file instructs the AI agent to execute `node -e` commands that directly embed user input variables (`CUPS`, `NEW_CUPS`) into the JavaScript string. If the OpenClaw platform does not strictly sanitize these variables to numerical values, an attacker could inject arbitrary JavaScript code, leading to unauthorized execution. While there is no explicit malicious intent (like data exfiltration or persistence) within the provided code, this mechanism presents a significant security risk.
Capability Assessment
Purpose & Capability
The artifact's stated purpose is to track water and sleep, and the observed commands only add, view, update, or delete records in `{baseDir}/health-data.json`.
Instruction Scope
The `node -e` examples use `CUPS` and `NEW_CUPS` placeholders; the skill says to replace them with numbers, so agents should validate those values as numeric before execution.
Install Mechanism
There is no install script or bundled executable, but the runtime instructions assume Node.js is available.
Credentials
File access is scoped to a single local JSON file, with no network calls, credentials, broad filesystem indexing, or third-party account access shown.
Persistence & Privilege
The skill intentionally persists water and sleep timestamps locally, which is proportionate but may reveal personal routine or health information.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install healthcheck - After installation, invoke the skill by name or use
/healthcheck - Provide required inputs per the skill's parameter spec and get structured output
