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_tool(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_tool() (incremental update).

1. Get review context by calling get_review_context_tool(). 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)

1. Analyze the blast radius by reviewing the impacted_nodes and impacted_files in the context. Focus on:

• Functions whose callers changed (may need signature/behavior verification)
• Classes with inheritance changes (Liskov substitution concerns)
• Files with many dependents (high-risk changes)

1. 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_tool(pattern="tests_for", target=<function_name>)
• Flag any untested changed functions

1. 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

Advantages Over Full-Repo Review

• Only sends changed + impacted code to the model (5-10x fewer tokens)
• Automatically identifies blast radius without manual file searching
• Provides structural context (who calls what, inheritance chains)
• Flags untested functions automatically
