Compiler-backed semantic editing

Intent-driven code editing
for AI agents

LLMs plan the change. Compilers and language servers apply it precisely.

An abstract code editor flowing into a precise compiler syntax tree

Make intent the interface

semedit separates semantic intent from syntax transformation, so agents can ask for the change while local tooling handles the mechanical work.

A compiler shield protecting a structured code module Deterministic editsUse compiler-backed transformations that preserve syntax and eliminate fragile line-based patching. A target resolved within a connected graph of symbols Symbol-based intentAsk for Server.Start instead of hunting for a byte offset or line number. Diagnostics resolving into a clear evidence graph Structured feedbackReceive formatting, diagnostics, and compiler evidence as structured results. Connected modules sharing one central contract One contract for agentsUse the same semantic operations through the CLI or MCP.

A tighter editing loop

  1. An LLM plans a high-level intent.
  2. semedit resolves the target symbol and selects the compiler or language server.
  3. The host applies and formats the change deterministically.
  4. Diagnostics return as evidence for the next decision.
