Team CR7 Builds Python Dependency Audit Tool Using Only Standard Library in 72 Hours

A three-person team called CR7 — comprising Anant, Ahil, and Dhanvin — built DepZero, a static code analysis tool, during the Zero Dependency 2026 hackathon organised by Hackathon Raptors. The challenge required participants to use only Python's standard library, with no third-party packages or pip installations permitted. DepZero uses Python's built-in AST module to scan source files, map where imported packages are actually used, and identify cases where standard-library modules could replace external dependencies. The tool can parse both pyproject.toml and setup.py manifests without executing them, flagging any dynamic declarations it cannot safely resolve. It targets Python 3.11 and above, leveraging newer standard-library features to keep the implementation clean and fully self-contained.
