AI system prompts are attack surfaces, not documentation

System prompts for AI models are vulnerable to various attacks, including paraphrase drift, priority inversion, and context bleed, rather than being secure documentation. These vulnerabilities arise because models may interpret prose-based instructions loosely or prioritize user input over system directives. To mitigate these risks, developers should treat system prompts as public attack surfaces, implement hard constraints in external harnesses like output filters and spend caps, and rigorously regression-test prompts with fixed probes and pinned model versions.

    <p>Every system prompt is a policy document. Nobody reads it. Some of it gets paraphrased into context by a user who found it in a public repo, and the rest gets probed by an automated scanner within an hour of your endpoint going public.</p> <p>That makes the system prompt exact…
