Roast your vibe-coded repo.
Fix the prompt that broke it.

Prompt Medic is a Discord bot for people shipping with Cursor, Claude Code and ChatGPT. /roast scores your GitHub repo out of 10 and flags security holes, bugs and quick wins. /fix tells you why your prompt isn't working and rewrites it. Bonus: short game patch-note digests with /patch.

/roast/fix/patch/mybuild

Before and after

Real /fix output, unedited. Brackets mark details only you know, so the rewrite never makes up your stack or your error.

Before
make my app look better
After /fix
Make my app look better. [PASTE APP DESCRIPTION OR CURRENT CODE HERE]. [DESCRIBE WHAT LOOKS BAD OR WHAT YOU WANT IMPROVED]. Use [YOUR TECH STACK]. Constraints: keep existing functionality unchanged and only modify styles/layout. Done = the app has a cleaner, more modern visual appearance that matches the provided description.

Why it failed: The prompt is extremely vague and provides zero context about the app, current design problems, tech stack, or desired improvements.

Before
my login is broken fix it
What went wrong

cursor rewrote half my files and it still 401s

After /fix
my login is broken fix it. It returns 401 errors. Only edit the minimal files needed. Do not rewrite unrelated code. First analyze the current login flow and [PASTE THE EXACT ERROR] plus any relevant logs. Then propose the smallest targeted fix. Done = login succeeds without 401 errors and no other files were changed.

Why it failed: The prompt is a single vague sentence with no context, error details, or constraints, so the AI has no idea what to preserve or where to look.

Before
write a tweet about my game
What went wrong

it sounds like a corporate ad

After /fix
Write a tweet about my game. Make it sound like a real player sharing excitement, not a corporate ad. Use casual, fun language and keep it under 280 characters. Include one specific hook about [ONE THING PLAYERS LOVE] and end with a call to action like trying the game. Done = a natural-sounding tweet that feels personal and engaging.

Why it failed: The prompt is extremely vague with no details on game genre, tone, audience, or desired style, so the model defaults to generic marketing language.

What it does

Four slash commands. The /roast and /patch outputs below are real, and the /fix one is an illustrative example.

/fix: prompt doctor

Paste a prompt that isn't working (and optionally what went wrong). You get a diagnosis, a rewrite, and tips.

Example (illustrative) 
/fix prompt: make the login work
Prompt MedicBOT
🩺 Prompt Medic DiagnosisThe prompt names no stack, no auth method, and no definition of "working", so the model guesses and rewrites unrelated code. Rewritten prompt
Add email/password login to my Next.js app using Supabase Auth. Keep the existing UI and routes. Show validation errors inline under each field. Done = I can sign up, log in, log out, and /dashboard redirects to /login when signed out. Don't modify files outside /app/(auth) and /lib/supabase.
Tips
  • State what "done" looks like
  • Name your stack and the files it may touch
  • One feature per prompt

/roast: repo roast

Drop a public GitHub URL or paste code. You get a score out of 10, security issues, bugs, quick wins, and a verdict.
