CCA-F: Claude Certified Architect — Foundations

You are developing developer-productivity tools with the Claude Agent SDK. The agent assists engineers in exploring unfamiliar codebases, understanding legacy systems, generating boilerplate code, and automating repetitive tasks. It uses the built-in tools (Read, Write, Bash, Grep, Glob) and integrates with Model Context Protocol (MCP) servers.

An engineer asks the agent to understand how the caching layer functions before adding a new cache-invalidation trigger. After initial Grep searches, the agent has determined that caching logic spans 15 files—including decorators, middleware, and service classes—covering approximately 8,000 lines total. What is the most effective next step to build understanding while managing context constraints?
