2323returns a 409 with `error_code` `plugin_name_taken` and, when a Plugin holds it,
2424that Plugin's ID in `details.plugin_id`. A Plugin going into the organization's
2525library marketplace is also refused with a 409 when one of its skills has the name of
26an organization skill (a skill an administrator uploaded for the whole organization
27in claude.ai): `error_code` `skill_name_taken`, with that name in
28`details.skill_name`; rename the skill, or remove the organization skill in
29claude.ai. A 503 with `error_code`
26an organization skill that this API does not list: `error_code`
27`skill_name_taken`, with that name in `details.skill_name`; rename the skill, or
28remove the organization skill in claude.ai. A 503 with `error_code`
3029`registration_pending` means the Plugin and its version were stored (their IDs are
3130in `details`) but are not yet usable in claude.ai: do not retry the create (the
3231retry would return `plugin_name_taken`); create a version on the stored Plugin

354 `remote` means it declares an MCP server or a CLI. `privileged` means it declares no MCP server or CLI, but declares a hook, monitor, language server, or settings, or has a skill, command, or other Markdown file whose frontmatter pre-approves tools (`allowed-tools` with any value other than an empty one or one that names only `AskUserQuestion`, `TodoWrite`, and `ToolSearch`). Otherwise it is `contained`.
355 `remote` means it declares an MCP server or a CLI, or something that counts as one. `privileged` means it is not `remote`, but declares a hook (of any type, even one that posts to a URL), monitor, language server, Claude Code workflow (any file in a `workflows/` folder at its root counts as one), or settings, or has a skill, command, or other Markdown file whose frontmatter pre-approves tools (`allowed-tools` with any value other than an empty one or one that names only `AskUserQuestion`, `TodoWrite`, and `ToolSearch`). Otherwise it is `contained`.

356 If the frontmatter of a skill, command, or other Markdown file that could change the value could not be read, or was past a size limit, the version is `null` or `privileged` (or `remote`, if it declares an MCP server or a CLI), not `contained`. The value is normally worked out when a version is stored, under the rules of that time, so an older version can be `null`, or `contained` where the same files stored today would be `privileged` or `null`.
357 If the frontmatter of a skill, command, or other Markdown file that could change the value could not be read, or was past a size limit, the version is `null` or `privileged` (or `remote`, if something else it declares makes it `remote`), not `contained`. The value is normally worked out when a version is stored, under the rules of that time, so an older version can be `null`, `contained` where the same files stored today would be `privileged`, `remote`, or `null`, or `privileged` where they would be `remote`.
