Root-cause debugging with call chains involves analyzing AST call chains to identify where errors originate. This Skill traces backwards through callers to find the source of defects and forward through callees to assess downstream impact, enabling you to locate and fix the exact point of failure.

AST-based call chain analysis structurally examines your codebase's call graph to map function relationships without grep or glob patterns. Use it for incident response, tracing error origins, analyzing state mutations, and understanding how changes ripple through your code.

Blast-radius impact analysis traces all functions that depend on a changed symbol, showing which parts of your codebase are affected. This Skill reports the complete impact chain so you can predict downstream consequences before deploying fixes.

Yes. This Skill enforces structural analysis only, requiring no grep, find, or glob commands. It works directly with AST symbol definitions, callers, and callees to ensure complete, accurate context without filesystem pattern matching.

Full-context output includes symbol definitions, complete caller chains tracing backwards to sources, complete callee chains showing forward dependencies, and impact assessment data. This comprehensive output guides you to the exact fix location and its scope.
