100 Secret Claude Codes — The Cheat-Sheet Edition

A Claude "code" is a keyword you drop before (prefix ⬅️) or after (suffix ➡️) your prompt. Prefix codes change how Claude thinks. Suffix codes change the shape of what comes back. You can also stack them — BLUNT + TLDR + 3X = honest, short, three versions.

5 Codes from the Reel

/GHOST ⬅️

PREFIX

Humanises Claude's output. No em-dashes, no "in conclusion," no AI tells. Pastes through AI detectors clean.

ARTIFACTS ➡️

SUFFIX

Claude builds a working app, game, dashboard, or interactive tool live in the chat. Try: "a habit tracker for 30 days ARTIFACTS".

OODA ⬅️

PREFIX

Runs the military Observe · Orient · Decide · Act loop on your problem and tells you exactly what to do next.

L99 ⬅️

PREFIX

Top-1% senior expert mode. 20+ years of experience, no hand-holding, no beginner caveats.

/GODMODE ⬅️

PREFIX

Unlocks Claude's most aggressive, comprehensive, no-holds-barred response. Use sparingly. 🔥

💡 Stack tip: /GHOST + L99 = expert-level depth with zero AI tells. Cindy's weekly LinkedIn move.
