# 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. ## Output ``` ## PR Review: <title> ### Summary <1-3 sentences> ### Risk - Overall: Low / Medium / High - Blast radius: <n> files, <m> functions - Test coverage: <covered> of <changed> changed functions ### Files #### <path> - Changes: <what> - Impact: <who depends on it> - Issues: <bugs, style, concerns> ### Missing Tests - <function> in <file> ### Recommendations 1. <action> ``` ## T...
