Description
Validates JSON, CSV, and Excel data with schema enforcement
Usage Guidance
This skill's code does valid JSON validation and schema inference, but it does not implement CSV or Excel parsing despite claiming to. Before installing or using: (1) confirm with the publisher whether CSV/Excel support exists or is planned; (2) treat the included data_validator.js as untrusted code—run it in a sandbox or test environment first and only on non-sensitive JSON files; (3) if you need CSV/Excel support, request a version that includes a well-known parser (e.g., csv-parse, papaparse, xlsx) and an install spec; (4) be aware that the script will read any file path you pass it, so avoid giving it paths to secrets or system config. If the publisher cannot clarify the CSV/Excel discrepancy, consider this skill untrusted for production use.
Capability Analysis
Type: OpenClaw Skill
Name: skylv-data-validator
Version: 1.0.2
The skill is a standard data validation utility that performs schema inference and validation for JSON files. The implementation in `data_validator.js` uses native Node.js modules (fs, path) to process local files and contains no network activity, obfuscation, or evidence of malicious intent.
Capability Assessment
Purpose & Capability
The skill advertises JSON, CSV, and Excel validation, but the included data_validator.js only parses and validates JSON files (JSON.parse, no CSV or Excel parsing libraries, no .csv/.xlsx handling). The README/metadata also lists version 1.0.0 while the registry shows 1.0.2. These discrepancies indicate the stated purpose is broader than the actual implementation.
Instruction Scope
SKILL.md is high level and consistent with running a validator, and the code's commands operate only on file paths supplied to the script. The instructions do not direct the agent to read unrelated system config or env vars. However, because the skill claims CSV/Excel support but the code only handles JSON, the agent or user might be misled into supplying non-JSON files which will cause failures or unexpected behavior.
Install Mechanism
There is no install spec (instruction-only), so nothing is automatically downloaded or written during install. The skill does include a JavaScript file; executing it requires Node and will read files provided by the user. No external URLs, installers, or archive extraction are present.
Credentials
The skill declares no required environment variables, no credentials, and no config paths. The code does not access environment variables or network endpoints. The requested environment access is proportionate to the declared functionality.
Persistence & Privilege
always is false, the skill is user-invocable, and model invocation is not disabled (normal defaults). The skill does not attempt to modify other skills or system-wide agent settings in the files provided.
