Tool-making agents compile repeated procedural steps into versioned tools before deployment.

arXiv 2607.08010 replaces the inference-time coding loop with a pipeline that collects execution traces, observes live backend schemas and values, synthesizes candidate tools, and repairs them against labeled cases. Runtime calls the compiled tool instead of re-deriving it. This is the practical middle ground between hardcoded pipelines and fully dynamic code generation, and it pairs naturally with programmatic tool calling: compile the tool once, let the model orchestrate it in JS.
