The TodoWrite Tool: When It Actually Helps

TodoWrite gives Claude Code an explicit task list it maintains as it works. It's a tool for long, branching work — and pure noise on simple tasks.

What TodoWrite does

TodoWrite is a tool the agent can call to maintain an explicit task list during a session. It writes the list, marks items in-progress, marks them complete, and re-reads it as it goes. The user sees the list update in real time, which gives the session structure a normal back-and-forth chat doesn't have.

When it helps

Multi-step work where the agent is genuinely tracking dependencies
Tasks complex enough that you want to see what the agent has and hasn't done
Long sessions where re-reading 'what's left' would otherwise burn context
Hand-offs — you can stop and resume because the list is the state
Branching work where one decision opens or closes other items

When it's overhead

Single-step tasks ('fix this typo') — the list is performance theater
Tasks short enough that the trace itself is enough
Conversational debugging where structure isn't the problem
Anywhere the list ends up out of date faster than the agent updates it

Apply: a quality test

For your next 5 sessions, note when the agent uses TodoWrite
Mark each as 'helped me track,' 'pure ceremony,' or 'genuinely structured the work'
Tune your prompts to ask for it on real work and discourage it on simple tasks
After a week, you'll know your own threshold

The big idea: TodoWrite is for genuinely multi-step work. Skip it on small tasks; use it as a debugging surface on big ones.
