Claude Code Power Features — quiz

A QA team notices that every Claude Code session starts with the same 10-minute back-and-forth where engineers explain the test framework, the folder structure, and which files are off-limits. What is the correct fix?

• Each engineer should save the explanation as a text snippet and paste it at the start of every session
• Write a CLAUDE.md file at the project root that documents the stack, conventions, and constraints — Claude Code loads it automatically at session start
• Create a shared Slack channel where engineers post the context before starting Claude Code
• Train a custom Claude model on the codebase — CLAUDE.md is only for small projects
