Reading Code Quickly

A focused code-reading skill for understanding a selected function, class, snippet, or file.

It explains the purpose and main flow with file and line references, reads one level of direct project-local callees, and locates one level of direct callers or entry points. It distinguishes declared contracts, implementation-based inferences, and unknown information.

Output: purpose, main flow, direct calls, project context, and reading takeaways. Instructions and default output are in Chinese. Intended for readers with a computer science background.

Scope: code orientation only. Not debugging, security or performance audits, refactoring, or deep architecture analysis. Missing definitions and dynamic dispatch may remain unconfirmed. Effectiveness has not yet been benchmarked.
