Review PR

Review PR

Review all commits of a pull request or branch against its base branch.

Steps

1. Identify the changes. With a branch name run git diff --name-only main...<branch>; otherwise diff the current branch against main (or master). Use that ref as base below.
2. Call get_minimal_context_tool(task="review PR", base="main"). If it returns status: not_ready, call build_or_update_graph_tool() and continue.
3. Call detect_changes_tool(base="main", detail_level="minimal") for risk-scored changed functions, test gaps and affected flows across the whole branch.
4. For high-risk functions call query_graph_tool(pattern="callers_of", target="<function>") and query_graph_tool(pattern="tests_for", target="<function>"). Flag public API changes whose callers were not updated.
5. Call get_review_context_tool(base="main") for source snippets, or get_impact_radius_tool(base="main") for the full dependent list, only when step 3 leaves a high-risk item unclear.
6. Read the changed source of the highest-impact files first. Do not load whole files unless the change needs it.
