Question 01 / 07

When should you delegate a task to a subagent?

Always — the main session should never do work directly.
When you need wide investigation whose useful output is a small summary, so the noise stays out of your main context.
Only when working with Module 4 features.
Whenever you want to write less code yourself.

Question 02 / 07

What does a Claude Code 'hook' do?

Generates a new prompt automatically.
Runs a shell command on your machine in response to a Claude Code event (PreToolUse, PostToolUse, Stop, etc.).
Hooks into Anthropic's servers for a discount.
Schedules a task to run later.

Question 03 / 07

What are MCP servers for?

Hosting your codebase.
Adding new tools Claude can use to talk to external services — Linear, Notion, your database, custom internal tools.
Making Claude run faster.
Storing your conversation history.

Question 04 / 07

Roughly when should you reach for Opus vs Sonnet vs Haiku?

Always Opus; cheaper models are inferior.
Haiku for high-volume bounded work, Sonnet as the default, Opus for genuinely hard reasoning or high-stakes work.
Always Haiku to save money.
Whichever is listed first in the model menu.

Question 05 / 07

Claude has been editing the same file five times in a row without progress. What's the right move?

Wait it out — eventually it'll figure itself out.
Interrupt with Esc, reset context if needed, and use plan mode to diagnose before more edits.
Switch to a different model and try the same prompt unchanged.
Restart your computer.

Question 06 / 07

What is a git worktree used for?

Visualising branches inside the IDE.
Checking out multiple branches in separate folders that share the same git history — useful for running parallel Claude agents without interference.
Storing a backup of your repo.
Submitting pull requests.

Question 07 / 07

The mindset shift 'from prompter to manager' is about...

Demanding completions faster.
Moving from typing every request yourself to delegating focused work to agents, reviewing output, and steering the whole flow.
Buying your manager a Claude subscription.
Becoming a manager at your company.
