Zero to Claude Certified Architect — Complete Exam Prep Series - Zero to Claude Certified Architect — Complete Beginner's Guide | Part 13: Built-in Tools

Welcome to Part 13 of the Zero to Claude Certified Architect series! We cover Task 2.5 — selecting and applying Claude Code's six built-in tools effectively. In this video, you'll learn the critical Grep vs Glob distinction, the two-phase search strategy for exploring unfamiliar codebases, when to use Edit vs Write, the Read+Write fallback pattern when Edit fails, and how to explore codebases incrementally without wasting context. Timestamps: 00:00 Quick Recap — Part 12 (MCP Servers) 01:48 The Six Built-in Tools Overview 03:30 Grep vs Glob — Content vs Name Search 05:20 The Search Strategy: Grep then Read 07:10 Edit vs Write — Targeted vs Full Replace 09:00 The Read+Write Fallback Pattern 10:30 Incremental Codebase Exploration 12:00 Five Anti-Patterns to Avoid 13:20 Six Exam Takeaways 14:30 Part 14 Preview — CLAUDE.md Hierarchy What you'll learn: - Grep searches file contents; Glob searches file names and paths — the #1 exam confusion point - The two-phase strategy: Grep to find entry points, then Read to understand the code - Edit for targeted single-occurrence changes; Write for new files and complete rewrites - The Read+Write fallback when Edit fails due to non-unique match - Incremental codebase exploration: follow imports step by step, never read everything upfront - Why Bash is for build/test/git operations, not for file search - Five anti-patterns that appear as wrong answer choices on the exam This is Part 13 of the Zero to Claude Certified Architect series, covering every domain and task in the Claude Certified Architect (Foundations) exam. In Part 12, we completed Domain 2 with MCP server integration. Now we wrap up Domain 2 with Task 2.5 — the built-in tools every developer needs to master. Coming up in Part 14: Domain 3 begins with Task 3.1 — configuring CLAUDE.md files. You'll learn the three-level hierarchy (user, project, subdirectory), the @import syntax for modular configuration, and the .claude/rules/ directory pattern.
