Can it check for missing tests?

Yes, the skill queries the graph to see if modified functions have corresponding tests and flags any untested changes as a high-risk finding.

Do I need to manually update the code graph?

No, the skill includes a tool to incrementally update the local knowledge graph automatically based on your latest git changes before the review begins.

What is 'blast radius' detection?

Blast radius detection identifies functions, classes, or files that might break because they depend on the code you just changed, ensuring you don't miss unintended side effects.

Does this work with any programming language?

As long as the underlying knowledge graph tool supports the language's structure and dependency mapping, Review Delta can analyze it.

How does Review Delta save tokens?

Instead of sending your entire codebase to the AI, it uses a local knowledge graph to identify only the changed code and its immediate 2-hop dependencies, reducing token usage by up to 49x.

コラボレーションツール

Performs focused, token-efficient code reviews by analyzing git diffs and their downstream blast radius via a local knowledge graph.

Review Delta is a specialized Claude Code skill designed to optimize the code review process by focusing only on what matters. By building a persistent local knowledge graph of your codebase, it identifies the "blast radius" of any change—mapping out impacted callers, inheritance chains, and dependent files. This allows Claude to provide deep structural insights while using up to 49x fewer tokens than traditional full-context reviews. It is particularly effective for identifying regression risks in complex systems and ensuring that new changes are adequately covered by tests without needing to upload the entire repository context.
