You'll notice
Marketplace directory collision check now runs in both directions
What
When fetching a plugin marketplace, Claude Code already checked whether the target directory was already registered as a different marketplace. It now also runs the reverse check, to see if the new marketplace's directory collides with an existing one the other way around.
Why
This closes a gap where a directory-name collision could previously be caught in one direction but not the other, giving a more reliable "cannot fetch this marketplace" error when clone directories conflict.
