A forge for Claude Code plugins.
Claude Anvil is a plugin marketplace containing nine Claude Code plugins for academic research, creative worldbuilding, publication workflows, site management, repository intelligence, personal metadata, encryption, and more. Each plugin provides skills, commands, and agents that extend Claude Code with domain-specific capabilities.

Each plugin follows Claude Code plugin conventions:
<plugin>/
├── .claude-plugin/plugin.json # Manifest: name, version, description, author
├── skills/<name>/SKILL.md # Interactive skills (the core logic)
├── commands/<name>.md # Slash commands (thin wrappers or rich docs)
├── agents/<name>.md # Autonomous subagents with system prompts
└── hooks/hooks.json # Event handlers (optional)
Skills are the heart of each plugin — they contain the domain knowledge and workflow logic. Commands are thin wrappers that trigger skills via /plugin:command syntax. Agents run autonomously for tasks like literature surveys or code review.
Not every plugin uses every component. Minimal plugins like deets have only a skill and a command. Larger plugins like worldsmith add hooks for ambient project detection and propagation discipline.
