What does 'blast radius' mean in software development?

Blast radius refers to the total scope of potential impact a single code change has on the rest of the system, including dependent files, modules, and downstream services.

How does the skill identify stakeholders?

The skill uses ownership analysis via the Omen CLI to look at commit history and file metadata, identifying the developers who most frequently modify the affected areas of the codebase.

Does this skill require any external software?

Yes, this skill requires the Omen CLI to be installed on your system and available in your PATH to perform the code intelligence analysis.

What is temporal coupling in the context of this skill?

Temporal coupling identifies files that are frequently committed together in version control history, suggesting a hidden relationship even if there is no explicit import statement between them.

分析与监控

Analyzes the potential impact and blast radius of code changes by mapping dependencies, temporal coupling, and ownership patterns.

The Impact Assessment skill provides deep code intelligence via the Omen CLI, enabling developers to visualize the consequences of refactoring core components or making breaking API changes before they happen. It maps direct and transitive dependencies while uncovering hidden 'temporal' relationships where files frequently change together despite lacking explicit imports. By identifying affected files and primary stakeholders, this skill helps teams mitigate risk, improve code quality, and ensure the right subject matter experts are involved in the review process.
