CCA-F: Claude Certified Architect — Foundations

You are creating developer-productivity tools with the Claude Agent SDK. The agent helps engineers explore unfamiliar codebases, understand legacy systems, generate boilerplate code, and automate repetitive work. It uses the built-in tools (Read, Write, Bash, Grep, Glob) and integrates with Model Context Protocol (MCP) servers.

You are building a security-scanning workflow.

When engineers must find every occurrence of a dangerous function such as eval() throughout a large codebase, which tool should the agent use to search file contents?
