Claude Code is Anthropic's official agentic coding CLI, and it is excellent at the inner loop: a single, capable agent that edits your codebase, runs commands, and iterates with you in one session. For focused day-to-day work, one Claude Code session is the right tool. Maestro does not replace it — Maestro runs on top of the same claude CLI and coordinates several sessions into specialised roles with quality and security gates, for work that outgrows a single thread.

TODO-VERIFY marks a Plain Claude Code capability we have not independently confirmed. We would rather flag it than misstate a competitor.
