Claude Code v2.1.304 ·

Saving the list of known plugin marketplaces now depends on the mode Claude Code runs in

Saving the known-marketplaces list no longer always locks the file; depending on mode it skips the save or writes without a lock

Unclear It is not clear which mode changes how the marketplace list is saved, so it is unclear whose setups are affected.

What

A plugin marketplace is a catalogue that Claude Code can install plugins from, and Claude Code keeps a list of the ones it knows about. Before, saving that list always locked the file first, so that two writers could not change it at the same time. Now the save depends on the mode Claude Code is running in:

  • In one mode, the save stops early. If the scope is raw, it is recorded as skipped.
  • Otherwise, the list is written without locking the file.

Claude Code can also now load seed marketplaces, which are marketplaces provided in advance. If a seed is missing, Claude Code shows a warning and carries on.

Why

In practice, saving the marketplace list behaves differently depending on how Claude Code is running. A missing seed marketplace produces a warning rather than an error.
