/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 one-liners and storing water and sleep history in `{baseDir}/health-data.json`. Cup values should be validated as numbers before execution, and deleted or overwritten records may not be recoverable unless you keep backups.
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 stated purpose is tracking water and sleep, and the artifact only provides commands to add, view, update, or delete records for that tracker.
Instruction Scope
The Node.js snippets use numeric placeholders for cup counts; agents should treat those as numbers only and avoid inserting arbitrary user text into the command.
Install Mechanism
No install script, bundled executable, network dependency, package installation, or automatic startup behavior is present; the instructions assume Node.js is available at runtime.
Credentials
File access is scoped to `{baseDir}/health-data.json`; there are no network calls, credential access, broad filesystem reads, or unrelated system changes.
Persistence & Privilege
The skill intentionally persists personal water and sleep history locally and includes immediate update/delete operations, including deletion of the last water record without an undo mechanism.
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
