使用说明 (SKILL.md)
DataGate
Validate any JSON payload against a JSON Schema.
Start the server
uvicorn datagate.app:app --port 8004
Validate data
curl -s -X POST http://localhost:8004/v1/validate \
-H "Content-Type: application/json" \
-d '{
"json_schema": {
"type": "object",
"properties": {"name": {"type": "string"}, "age": {"type": "integer", "minimum": 0}},
"required": ["name", "age"]
},
"payload": {"name": "Alice", "age": 30}
}' | jq
Returns valid (true/false), error_count, and errors (each with path pointing to the exact field and message explaining the violation).
Handles invalid schemas too
If you send a broken schema, DataGate catches it and returns an error pointing to $schema with a clear message. No crashes.
Use case
Agents passing data between services can validate payloads before sending. Non-Python agents get Pydantic-grade validation via a simple API call.
安全使用建议
This skill is internally consistent and implements a local JSON Schema validation API. Before installing: run it inside a controlled environment (virtualenv/container) so pip installs don't affect system packages; be aware running the server binds a network port — bind to localhost or firewall it if you don't want external access; vet PyPI package sources per your org policy; and avoid exposing the endpoint to untrusted clients because malicious or deeply recursive schemas/payloads could cause high CPU/memory use (denial-of-service risk).
功能分析
Type: OpenClaw Skill
Name: datagate
Version: 1.0.0
The 'datagate' skill bundle is a legitimate utility for validating JSON payloads against JSON Schemas using FastAPI and the jsonschema library. The implementation in datagate/app.py and datagate/models.py is straightforward, follows best practices, and contains no evidence of malicious intent, data exfiltration, or suspicious execution patterns.
能力评估
Purpose & Capability
Name/description match the code and runtime instructions. Required binary (python) and listed Python packages (fastapi, uvicorn, pydantic, jsonschema) are appropriate for a small validation HTTP service.
Instruction Scope
SKILL.md instructs running a local uvicorn server and shows a single POST /v1/validate endpoint. The instructions do not read unrelated files, env vars, or send data to other endpoints.
Install Mechanism
Install spec indicates Python packages (PyPI-style). This is a standard, expected install method for a Python FastAPI app; no downloads from arbitrary URLs or extraction of remote archives were found.
Credentials
The skill declares no required environment variables or credentials and the code does not access secrets or external configs. Required dependencies are limited to those needed for the service.
Persistence & Privilege
always:false and no special privileges requested. The skill runs as a normal local HTTP service and does not attempt to modify other skills or system-wide settings.
