# Reserved Plugin and Marketplace Names

These names are blocked for third-party use by the Claude Code marketplace. Reject any
plugin or marketplace name that matches an exact entry or a wildcard pattern below.

## Exact reserved names

```
claude-code-marketplace
claude-code-plugins
claude-plugins-official
claude-plugins-community
claude-community
anthropic-marketplace
anthropic-plugins
agent-skills
anthropic-agent-skills
knowledge-work-plugins
life-sciences
claude-for-legal
claude-for-financial-services
financial-services-plugins
```

## Reserved name patterns (prefix match)

Any name starting with these strings is reserved:

```
anthropic-
claude-
official-claude
anthropic-tools
```

## Kebab-case requirement

Plugin names must match `^[a-z0-9]+(-[a-z0-9]+)*$` — lowercase letters, digits, and
hyphens only. No underscores, spaces, or uppercase. The Claude.ai marketplace sync rejects
non-kebab-case names even if the local CLI tolerates them.

## How to check

1. Exact match: is the name in the exact reserved list above?
2. Pattern match: does the name start with any reserved prefix?
3. Format: does the name match the kebab-case regex?

If any check fails, halt and ask the user for a different name before continuing.
