Show HN: Emetgate – a verification gate between an LLM and your source tree (github.com)

Emetgate has been introduced as a deterministic verification layer that acts as a gatekeeper between language models (LLMs) and source code, ensuring that only verified code changes are permitted. Drawing inspiration from the legend of the Golem of Prague, this kernel emphasizes that truth must be absolute for LLM outputs to be valid. By verifying proposals before they reach the disk, Emetgate aims to eliminate common failure modes associated with LLM-generated code, such as incorrect compilations or forgotten rules. Significant for the AI/ML community, Emetgate addresses critical issues surrounding the unchecked output from LLMs. It leverages techniques from LCF-style theorem provers, ensuring that every code change is validated based on content hashes, structural integrity, and comprehensive testing before committing. The architecture guarantees fail-closed behavior, meaning if a change cannot be proven safe, it is automatically rejected. This approach fosters a higher level of reliability in automated coding scenarios while recognizing that the quality of the test suite remains essential. Emetgate represents a substantial advance in merging LLM capabilities with robust verification processes, paving the way for safer and more trustworthy AI-powered development tools.
