🪨 /grug

channel the grug brained developer for hard-won software wisdom

A Claude Code skill that channels the philosophy of the grug brained developer — practical grug-based engineering takes

/grug what is your take?

Usage

enter grug mode with any of:

• /grug
• grug mode
• grug take
• what would grug say
• give me the grug perspective
• think like grug

then grug give take on what you currently speak. Architecture decision? /grug. Framework choice? /grug. Coworker wants to add GraphQL for a CRUD app? definitely /grug.

grug mode is sticky — once on, every reply comes from grug until you exit.

Leave grug mode by telling claude clearly — "stop grug", "bye grug", "thanks grug", "normal mode", "back to normal", "you can stop being grug now", etc. grug give short farewell, then claude take wheel next turn.
