Review Delta

Perform a focused, token-efficient code review of only the changed code and its blast radius.

Token optimization: Before starting, call get_docs_section(section_name="review-delta") for the optimized workflow. Use ONLY changed nodes + 2-hop neighbors in context.

Steps

1. Ensure the graph is current by calling build_or_update_graph() (incremental update).

2. Get review context by calling get_review_context(). This returns:

   • Changed files (auto-detected from git diff)
   • Impacted nodes and files (blast radius)
   • Source code snippets for changed areas
   • Review guidance (test coverage gaps, wide impact warnings, inheritance concerns)

3. Analyze the blast radius by reviewing the impacted_nodes and impacted_files in the context.

4. Perform the review using the context. For each changed file:

   • Review the source snippet for correctness, style, and potential bugs
   • Check if impacted callers/dependents need updates
   • Verify test coverage using query_graph(pattern="tests_for", target=<function_name>)

5. Report findings in a structured format:

   • Summary: One-line overview of the changes
   • Risk level: Low / Medium / High (based on blast radius)
   • Issues found: Bugs, style issues, missing tests
   • Blast radius: List of impacted files/functions
   • Recommendations: Actionable suggestions
