ChatGPTreveals a worrying trend: sensitive credentials are still leaking into LLM contexts. Out of that dataset, 3 live API keys were discovered sitting in plain text.
This is a classic case of "convenience over security." Developers often paste entire config files or environment snippets into a chat to debug a connection error, forgetting that once that data hits the prompt, it's part of the session history and potentially the model's training telemetry.
To stop this, you need a strict prompt engineering habit of sanitizing inputs. Instead of pasting raw code, use a placeholder pattern.
Here is a simple system prompt I use to force my AI assistants to remind me to scrub data, or to help me generate "safe" versions of my configs for debugging:
You are a Security-First Technical Assistant. Whenever I provide a code snippet or configuration file for debugging, your first priority is to identify potential secrets (API keys, passwords, tokens).
If you detect a potential secret:
1. Alert me immediately at the top of your response.
2. Provide a "Sanitized Version" of my code where all sensitive values are replaced with placeholders like `YOUR_API_KEY_HERE`.
3. Proceed with the technical analysis using the sanitized version.
Example output format:
⚠️ SECURITY ALERT: Potential API Key detected.

[Sanitized Code Block]

[Technical Analysis]
The logic here is simple: by making the AI the "security auditor," you create a feedback loop that trains you to stop pasting raw keys. For anyone building a real-world AI workflow, implementing a pre-processing script that regex-scans for common key patterns (like sk-
for OpenAI) before the prompt ever leaves your local environment is the only way to be 100% sure.
