Format JSON Online is a fast, free, and privacy-focused tool to format, validate, minify, and beautify JSON data directly in your browser. Built for developers and API testers, it offers support for large JSON files without requiring login or sending data to a server. Additional features like JSON-to-CSV, JSON-to-XML, and cURL conversion make it a versatile tool for debugging, transforming, and visualizing JSON. Light ads may be introduced in the future to support development, but user privacy and experience will always be top priorities.

This is why eval and observability ship as a unit, not as separate purchases. agent-eval scores and gates the output โ the tiers above, drift, hallucination. AgentLens captures the trace of how the agent got there: every model step and tool call, the resolved inputs, the raw outputs, the trajectory.

The real fragility is in trying to constrain arguments. The docs are explicit that a pattern like Bash(curl http://github.com/ *) fails to do what it looks like it does. It won't match curl -X GET http://github.com/... (option before the URL), curl https://github.com/... (different protocol), curl -L http://bit.ly/xyz (redirects to GitHub), URL=http://github.com && curl $URL (variable), or curl http://github.com... - Source: dev.to / 5 days ago
