Domino is a dependency-upgrade impact analyzer for Python codebases. Given a package and a version change, it builds a static dependency graph across the repo, diffs the package API between versions, matches the changed symbols to real code usage, and shows the blast radius across files, callers, tests, and entrypoints. It outputs a conservative upgrade verdict and structured evidence, and uses Codex to explain the findings in plain English.
