prelint is a product verification layer that ingests your specs, tickets, call transcripts, emails, and documentation and turns them into guardrails that run across your CI pipelines, CLI, and pull requests. It plugs directly into your GitHub workflow so reviews happen where your team already works instead of in a separate tool. By synthesising that material into a product knowledge graph, prelint flags product‑level drift introduced by AI agents and developers and lets leaders decide what is allowed to ship.
