cngx is an open-source CLI tool designed for developers working with coding agents. It fingerprints the output of coding agents and enforces merge gating, ensuring that only verified code is merged. The tool helps maintain code safety and integrity by detecting behavioral drift and enforcing policy checks.
In the LLM eval & observability space, cngx takes a focused approach. It focuses on ensuring that code generated by coding agents is verified before being merged, preventing unverified or unsafe changes. It is built as an open-source project for developers using coding agents and automated code generation tools. cngx is open source under the MIT license. The product ships for the command line.
Behind cngx is aadi-joshi, and the product first shipped in 2026. Development happens publicly on GitHub with 40 commits in the last 90 days. PulseGate's similarity index finds few close equivalents — cngx occupies a relatively distinct niche. Key capabilities include behavioral fingerprinting, merge gating, and policy checks.
