I built a tool that learns structural code transformations from a single before/after example.It isn’t a transformer or LLM — it doesn’t generate code. It extracts the structural pattern between two snippets and compiles a deterministic rewrite rule. Same input → same output, every time.Examples: • console.log(x) → logger.info(x) generalises to console.log(anything) • require(“x”) → import x from “x” • ReactDOM.render → createRoot • custom project conventionsThe rules apply across an entire codebase or through an MCP plugin inside Claude Code, Cursor, or plain CLI.It runs entirely on CPU and learns rules in real time.Tool: https://hyperrecode.com I’d really appreciate feedback on the approac

The company sits in the show hn launch segment, where it competes on its core product or service.

It is recorded at the Show HN launch stage.
