I Tested 100 Claude 'Secret Codes' — Only 5 Actually Changed the Output

What Are Claude Secret Codes?

Claude Secret Codes are prompt shortcuts you type at the start of your message to change how Claude responds. Each code activates a specific mode, format, or reasoning pattern — turning a generic AI response into exactly what you need.

There are two types:

• Slash commands like /ghost, /deepthink, /godmode — type with the forward slash
• UPPERCASE commands like BEASTMODE, PARETO, ARTIFACTS — type in all caps

Why Use Them?

Most people type vague prompts and get mediocre responses. These codes force Claude into specific modes that produce dramatically better output.

Instead of: "Help me write better"

Try: /ghost Rewrite this paragraph so it sounds completely human-written.
