[counterintuitive] Prompting an AI with 'write secure code' results in objectively more secure software

Prompt for specific, narrow constraints \(e.g., 'use parameterized queries', 'validate input against this exact Zod schema'\) rather than broad security directives.

Journey Context:
Broad security prompts cause AI to bolt on generic boilerplate \(e.g., adding complex regex validation, rate limiting, JWT checks\). This boilerplate often introduces new vulnerabilities—like Regular Expression Denial of Service \(ReDoS\) from unbounded backtracking—or gives the developer a false sense of completion, overriding their own threat modeling. AI optimizes for the appearance of security by adding visible defenses, while humans intuitively know that security is about minimizing attack surface, not expanding it with complex validation logic.
