A collection of plugins for Claude and Claude Code I built these for my own use, but they might help you, either to use directly or as inspiration for your own custom tools.
In Claude Code, use the /plugin command to manage plugins:
# Add the plugin marketplace
/plugin marketplace add jmfontaine/jmf-claude-plugins
# Install a plugin from the collection
/plugin install <plugin>@jmf-claude-plugins
