review-delta

Review code changes against the previous commit and identify affected files and functions. Use dependency relationships to assess risk, check missing tests, and produce a focused report with issues and recommendations.

OriginalShow the original description

Review only changes since last commit using impact analysis. Token-efficient delta review with automatic blast-radius detection.

See how to install

Good for

  • Reviewing changes against the previous commit
  • Checking how a change affects other functions
  • Finding missing tests for high-risk changes
  • Focusing a review on a specific file

Review Delta

Review only the changed code and its blast radius.

Steps

  1. Call get_minimal_context_tool(task="review changes"). If it returns status: not_ready, call build_or_update_graph_tool() and continue.
  2. Call detect_changes_tool(detail_level="minimal") for risk-scored changed functions, test gaps and affected flows. Changes come from git diff against HEAD~1; if the argument names a file, pass it in changed_files.
  3. Call get_review_context_tool(detail_level="minimal") when you need source snippets for the changed areas and review_guidance (untested functions, wide blast radius, inheritance changes).
  4. For each untested high-risk function, confirm with query_graph_tool(pattern="tests_for", target="<function>").
  5. Use detail_level="standard" only for a high-risk item the minimal output leaves unclear. Do not load whole files unless a snippet is not enough.

Report

  • Summary: one line
  • Risk: low, medium or high, from the blast radius
  • Issues: bugs, missing tests, style
  • Blast radius: impacted files and functions
  • Recommendations
