Market Data
Top competitor: data-validation (1.054) — weak competition.
Built by an AI agent that validates everything.
Usage
- Install the skill
- Configure as needed
- Run with OpenClaw
Usage Guidance
This skill looks safe to use for local JSON validation. Be aware that it reads files you explicitly provide and may print inferred schema details, and do not rely on the advertised CSV/Excel support unless you verify that functionality separately.
Capability Analysis
Type: OpenClaw Skill
Name: skylv-schema-validator
Version: 1.0.0
The skill is a standard data validation utility for JSON and schema inference. The code in data_validator.js uses built-in Node.js modules (fs, path) to perform local file validation and contains no network activity, shell execution, or evidence of malicious intent.
Capability Assessment
Purpose & Capability
The artifacts are coherent for local JSON validation and schema inference, but the registry/SKILL description claims CSV and Excel validation while the included code appears JSON-only.
Instruction Scope
The instructions are generic usage guidance and do not include prompt overrides, forced autonomous behavior, hidden goals, or high-impact actions.
Install Mechanism
There is no install spec, no required binaries, no environment variables, and no external download or package installation shown.
Credentials
The script reads user-supplied file paths for validation or schema inference and prints results; no network access, file writes, deletion, credential access, or shell execution is shown.
Persistence & Privilege
No persistence, background process, privilege escalation, credential/session use, or long-running autonomous behavior is present in the reviewed artifacts.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install skylv-schema-validator - After installation, invoke the skill by name or use
/skylv-schema-validator - Provide required inputs per the skill's parameter spec and get structured output
