How Coding Agents Think, Act, and Fix Real Software Systems

A coding agent must search for authentication flows, related services, dependencies, and tests before proposing changes to add account recovery to a large service, grounding its solution in the local architecture to reduce unsupported assumptions.

A coding agent must add account recovery to a large service with thousands of files. What should it do before proposing changes? A Load the complete repository into the model context. B Search for authentication flows, related services, dependencies, and tests. C Generate a standard recovery design from general knowledge. D Modify the first file containing the word password. Correct Answer: B Search for authentication flows, related services, dependencies, and tests. A reliable coding agent must first understand how the repository currently handles authentication, users, tokens, notifications, and security checks. It should use repository maps, symbol search, semantic retrieval, and dependency information to identify likely entry points. It should then inspect the actual implementation and related tests before planning edits. This approach grounds the solution in local architecture and reduces unsupported assumptions. It also reveals shared components that may be affected, such as session management, rate limiting, audit…
