Before claiming, check if a name is blocked:

Package Diagnosis

Name: openchat

Validation: passed
Registry: not found
Status: blocked
Reason: too similar to existing package

Conflicting packages:
  - open-chat

Both normalize to "openchat"

NPM blocks names that normalize to the same string after removing hyphens and underscores.
