Xenon

Open-source terminal AI coding agent that verifies its own claims against tool evidence.

Pluginfreeglobal

Xenon is an open-source terminal AI coding agent built around a verification system that treats the model's own output as a claim and only tool results as evidence, aimed at reducing hallucinated or unverified changes. It reports a published SWE-bench Lite benchmark result and supports multiple reasoning approaches and MCP tools. It is aimed at developers who want an AI coding agent with a built-in check against hallucinated fixes.
