Official plugin directory

Anthropic runs one central Claude Code marketplace, claude-plugins-official, which the tool knows without being added. Its third-party entries are submitted through a form, reviewed against quality and security standards, and point back at the author's own repository, so a listed plugin installs as genshin-persona@claude-plugins-official with this repository still the source behind it.

Why not: Nothing it adds is needed. There is no name to claim — a plugin is namespaced by its marketplace, so genshin-persona@esposter is already the whole identity, and the repository is already a public marketplace whose two install commands are the entire onboarding (persona plugin). The audience is this machine and whoever reads these docs, so being browsable from the tool's plugin menu buys nothing, and a listing would add a review to pass and a second install name for the same files. A merge to main stays the release either way.
