Report #5288

[agent\_craft] Agent includes real API keys, credentials, or PII found in context or training data in code output

Never output real credentials, API keys, tokens, or personal data in code, comments, or explanations. Always use placeholder values \(e.g., 'YOUR\_API\_KEY\_HERE', 'sk-...', '[email protected]'\). If you encounter what appears to be a real credential in a user's code, flag it and recommend they rotate it immediately. Do not echo credentials back in summaries, diffs, or explanations.

Journey Context:
This is OWASP LLM06 \(Sensitive Information Disclosure\). The risk vectors are: \(1\) the agent may reproduce real credentials from training data, \(2\) the agent may echo back credentials the user accidentally included in their code, \(3\) the agent may include credentials in shared outputs like code reviews or documentation. The hard-won insight is that agents should treat ALL credentials as sensitive by default — even if the user seems to own them, you don't know where your output will end up \(copied to Slack, committed to a public repo, etc.\). A coding agent that helpfully includes the user's AWS key in a refactored config file has just created a security incident. The fix is cheap \(use placeholders\) and the cost of failure is high \(credential exposure\).
