# Review Delta Perform a focused, token-efficient code review of only the changed code and its blast radius. **Token optimization:** Before starting, call `help(topic="graph")` for the full actions reference. Use ONLY changed nodes + 2-hop neighbors in context. ## Steps 1. **Ensure the graph is current** by calling `graph(action="update")`. 2. **Get review context** by calling `review()`. 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. 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) 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(action="query", pattern="tests_for", target=<function_name>)` - Flag any untested changed functions 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, mis
