Does it support identifying external service calls?

Absolutely. The tracer includes boundary detection that automatically flags and categorizes calls to external APIs, databases, and third-party libraries.

Is this skill useful for debugging errors?

Yes, it is specifically designed for identifying error paths. You can trace the entire flow of an error handling process to see where a failure might be swallowed or triggered.

Can it show me where specific data originates?

Yes, the skill supports data origin queries. Simply run a command like `/sourceatlas:flow "where does userProfile come from"` to see the flow of that specific data object.

How do I start tracing a specific feature?

You can initiate a trace by using the command `/sourceatlas:flow` followed by a natural language description of the feature, such as 'user login' or 'handleSubmit'.

What kind of output should I expect?

The skill returns a structured ASCII tree visualization representing the call graph, along with entry point identification and logic markers for recursion or cycles.

開発者ツール

Traces complex execution paths and data flows to visualize how features are implemented across any codebase.

Code Flow Tracer is a powerful exploration and diagnostic tool designed to help developers navigate unfamiliar codebases by generating comprehensive execution maps. By leveraging advanced boundary detection and ASCII tree visualizations, it allows users to pinpoint entry points, identify recursive loops, and understand the relationships between local functions and external services like APIs, databases, or cloud providers. Whether you are debugging an error path, performing a security audit, or onboarding onto a new project, this skill provides the architectural clarity needed to understand system behavior without manual source code trekking.
