agentnb

Use this when working in a repo that has agentnb installed or under development and the task benefits from a persistent Python REPL instead of one-off Python commands. Covers starting the project-scoped kernel, executing code, inspecting live state, recovering from failures, and shutting the session down cleanly.

Use this when the user asks for a thorough code review, full review, nitpicky review, architecture review, or test quality review. Produces a detailed review that checks clean code, clean typing, John Ousterhout style architecture, and test quality including pytest fixtures, parameterization, pytest-mock usage, behavior-vs-implementation testing, and useless/no-op tests.
