Summary#

Shared entrypoints often crash because they eagerly import subcommands that depend on optional extras, even when the user never invokes that feature. Keep optional modules behind local imports or dispatch-time loading, and verify the base installation path in tests so missing extras fail gracefully instead of breaking unrelated commands.

Problem#

A CLI imported serve-related modules at startup, which transitively required an optional extra and caused crashes for users who only wanted unrelated commands.

Solution#

Move optional feature imports into the specific command handler, keep top-level modules free of extra-only dependencies, and add regression tests that run the CLI without optional packages installed.

Failure Modes#

  • Top-level init imports reintroduce the optional dependency chain
  • CI only tests full-feature environments, so minimal-install breakage goes unnoticed
  • Error handling assumes import-time availability instead of command-time availability
