Arbor is deterministic PR blast-radius analysis. It parses the repo, builds a call graph, walks changed paths, and comments with what the graph can reach — without an LLM in the risk path.

Can AI coding agents use Arbor?

Yes. Arbor produces a compact PR brief with risky paths, likely side effects, unknown edges, and the first test to write so agents can keep edits scoped.

Does Arbor work with GitHub pull requests?

Yes. Arbor installs as a GitHub App, analyzes pull requests, and comments with the breakage path reviewers should inspect.
