Documentation

README

Excerpt

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

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

This is the opening of the README. Read the full README on GitHub.
