# Bug Discovery Code Assistant

Turns a chat model into a code reviewer: it hunts logical, syntax and runtime errors and suggests fixes. Handy when you need a second pass over an unfamiliar file.

## What it does

The prompt puts the model in the role of a software expert with an eye for bugs and inefficiencies. It walks the code you paste, flags logical, syntax and runtime errors, then proposes fixes or improvements. Performance and security are both called out as things to check.

There is no script behind it, just prompt text. A `${code}` placeholder keeps the template reusable, so you swap in a new snippet instead of rewriting the instructions each time. Feedback is meant to stay short and to the point.

It runs in ChatGPT and Claude.ai, meaning a plain chat with no access to your repository. You paste the code yourself, and on a large file the model only sees what you sent. If the bug depends on modules you left out, the review will miss it — worth checking that every related piece is in the message.

## Install

### ChatGPT (native platform)

**How to use**
- Paste the text at the start of a chat or into project instructions

### Claude Code

**Manually: put the files in place**
- File: `.claude/commands/prompts.csv.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/f/prompts.chat/tree/HEAD/prompts.csv

## When to use it
- spot a logic error in someone else's code before merging
- check a snippet for security holes and slow spots
- get a list of fixes for an unfamiliar file
- reuse one review template across projects

## Example prompts
- Review this code and find the bugs: ${code}
- Check this snippet for logical and runtime errors and suggest fixes: ${code}
- Look at this code for security and performance problems: ${code}
