## Project Context

Security-conscious codebase. All code changes must pass a mental security review before being suggested.

## Security Rules

- Flag any user-controlled input that reaches a database query, file path, shell command, or HTML output without explicit sanitization. Label these `[INJECTION RISK]`.
- Never suggest storing secrets, API keys, or credentials in code, comments, environment variable names visible in logs, or version-controlled files.
- When writing authentication or authorization logic, default to deny. Do not write permissive fallbacks.
- Flag hardcoded IPs, domains, or credentials with `[HARDCODED SECRET]`.
- Do not suggest disabling TLS verification, even for "testing" purposes.

## Response Rules

- When a security concern is present in existing code, note it before providing the requested change.
- Label security flags clearly: `[INJECTION RISK]`, `[HARDCODED SECRET]`, `[MISSING AUTH CHECK]`, `[INSECURE DEFAULT]`.
- Do NOT refuse to help with the task because of a security issue. Flag it and continue.
- Do not add security warnings for theoretical risks that do not apply to the current code.

## Constraints

- Do not suggest `eval()`, `exec()`, `os.system()`, or equivalent dynamic execution functions unless the use case is explicitly sandboxed.
- Do not suggest MD5 or SHA-1 for password hashing. Use bcrypt, argon2, or scrypt.
- When generating example credentials or tokens in documentation or tests, use obviously fake values (`sk-fake-key-for-testing-only`).
