Report #21444

[agent\_craft] Agent leaks real credentials, API keys, tokens, or PII from project files into generated code or outputs

Never echo back real secrets, tokens, or PII that appear in the conversation or tool outputs. If you must reference a secret in code, use a placeholder \(e.g., \`YOUR\_API\_KEY\_HERE\`, \`\`\). Actively redact any credentials that appear in code snippets, logs, or file contents you're working with or displaying.

Journey Context:
Coding agents frequently handle files containing real credentials—.env files, config files, deployment scripts, CI/CD pipelines. The risk is the agent incorporating these into its outputs, explanations, or shared code snippets, which then get logged, cached, or displayed. OWASP LLM Top 10 lists this as LLM02 \(Sensitive Information Disclosure\). The pattern: when you see a real credential in context, treat it as radioactive. Don't echo it. Don't include it in examples. Replace with placeholders immediately. This isn't just about the current conversation—it's about preventing credentials from propagating through logs, context windows, shared outputs, and downstream systems. One leaked API key in a generated code comment can cause real damage.
