Python source code type annotation tool
Project description
typify-prototype
Prototype backend CLI for Typify, a lightweight usage-driven static analyzer for precise Python type inference. Published at the 34th IEEE/ACM International Conference on Program Comprehension (ICPC 2026), Rio de Janeiro, Brazil.
Typify infers types for variables, function parameters, and return values in unannotated Python codebases using symbolic execution, fixpoint analysis, and cross-module dependency resolution — no training data or existing annotations required.
Given a Python project directory, the tool produces a JSON file per source file describing inferred types at every resolved identifier, plus a top-level index.json. This output is intended to be consumed by the Typify VS Code extension. See schema.md for the full output format.
