prompt-snippets

Type ;review or ;tests and it expands into a full instruction.

Short ;name shortcuts in a prompt expand to reusable instructions before Claude sees them. Ships with ;review ;tests ;plan ;explain ;short ;fix, and you can add your own.

Install

/plugin marketplace add cloudcruncher/claude-mod-garage
/plugin install prompt-snippets@mod-garage

Run /reload-plugins (or restart Claude Code) afterwards. To try it from a local clone without installing: claude --plugin-dir ./dev-mods/prompt-snippets

Use it

  • Type ;name anywhere at the start of a word in a prompt.
  • /snippets lists everything available.
  • Add your own with the extraSnippets option (a JSON object).
