Blast Radius Mapper

Blast Radius Mapper is an AI-powered Visual Studio Code extension designed to prevent catastrophic, silent failures in enterprise software architecture. When a developer modifies a core utility, class, or method, standard IDEs only flag structural compilation errors. They are blind to the cascading logical and semantic failures that frequently cause production outages. Blast Radius solves this by acting as an automated architectural guardrail right inside the developer's local environment. The extension intercepts unsaved code changes and runs a two-step verification pipeline. First, it utilizes an Abstract Syntax Tree (AST) parser to deterministically trace and extract every downstream file that imports or relies on the modified code. Second, it feeds this precise dependency graph and the Git diff to IBM Bob via local shell orchestration. Acting as a senior enterprise architect, IBM Bob semantically evaluates the intent of the change against the dependent files to assess the risk of logical runtime failures. Finally, the extension generates a dynamic, color-coded dependency graph (via Mermaid.js) directly inside a VS Code Webview tab. By visually categorizing downstream impact into Critical, High, or Low risk tiers, Blast Radius allows developers to immediately understand their architectural footprint and fix hidden regressions before a Pull Request is ever opened.
