What's Wrong?

Attempting to create a custom marketplace hosted on GitHub and the naming convention appears overly strict.

When creating a marketplace within an organization, it is highly likely to want to have -claude- of some variant in the naming. Presently, the reserved keywords block many permutations of this.

❯ /plugin marketplace add dagster-io/dagster-claude-plugins
  ⎿  Error: Invalid schema: name: Marketplace name cannot impersonate official Anthropic/Claude marketplaces. Names containing
     "official", "anthropic", or "claude" in official-sounding combinations are reserved.

❯ /plugin marketplace add dagster-io/claude-dagster
  ⎿  Error: Invalid schema: name: Marketplace name cannot impersonate official Anthropic/Claude marketplaces. Names containing
     "official", "anthropic", or "claude" in official-sounding combinations are reserved.

❯ /plugin marketplace add dagster-io/dagster-claude-code
  ⎿  Error: Invalid schema: name: Marketplace name cannot impersonate official Anthropic/Claude marketplaces. Names containing
     "official", "anthropic", or "claude" in official-sounding combinations are reserved.

https://code.claude.com/docs/en/plugin-marketplaces#github-repositories

Reserved names: The following marketplace names are reserved for official Anthropic use and cannot be used by third-party marketplaces: claude-code-marketplace, claude-code-plugins, claude-plugins-official, anthropic-marketplace, anthropic-plugins, agent-skills, life-sciences. Names that impersonate official marketplaces (like official-claude-plugins or anthropic-tools-v2) are also blocked.

Additionally, asking the AI assistant within the docs suggested names that also appear to be incompatible with the naming convention.

What Should Happen?

Should be able to have claude in some way in the name, perhaps just not prefixed with it.
