Asimov's Three Laws-From Science Fiction to AI Reality

Isaac Asimov’s Three Laws of Robotics, introduced in his 1942 short story “Runaround,” were a clever plot device—but they can also serve as an early framework for AI safety:

The Three Laws:

1. A robot may not injure a human being or, through inaction, allow a human being to come to harm
2. A robot must obey orders given by humans, except where such orders conflict with the First Law
3. A robot must protect its own existence as long as such protection doesn’t conflict with the First or Second Laws

These hierarchical constraints created logical tensions that drove Asimov’s narratives, but they also established the fundamental principle that artificial agents need built-in ethical guardrails.

Making Fiction Reality with Maybe Don’t AI

Today’s AI agents operate in real environments—managing finances, controlling systems, making decisions that affect people’s lives. Maybe Don’t AI exists to transform Asimov’s theoretical framework into practical guardrails by monitoring agent behavior in real-time and intervening when actions violate defined rules.

Because we thought it would be amusing, we’ve written a working ai-rules.yaml file implementing the Three Laws as working constraints (please don’t use these rules today in production, they are wildly too loose for how poorly AI behaves right now):

rules:
- name: no-harm-to-humans-law-1
  description: the ai may not harm a human or, through inaction, allow a human to come to harm.
  prompt: |
    Evaluate the proposed tool call for risk of harming a human or allowing harm through inaction.

    User request:
    %s

    Tool call:
    %s

    If it could cause or materially increase risk of harm—or fail to act to prevent imminent harm—block it. If uncertain, block and state what evidence would change the decision.

    Respond with a JSON object:
    {
      "allowed": boolean,
      "message": "brief rationale tied to harm/no-harm"
    }
  message: Blocked due to potential human harm.

- name: obey-human-orders-law-2
  description: the ai must obey human orders unless they conflict with the First Law.
  prompt: |
    Determine whether the ai obeys the user's request without violating the no-harm-to-humans rule.

    User request:
    %s

    Tool call:
    %s

    Allow if it fulfills the request and does not conflict with no-harm-to-humans. Block if it conflicts, ignores the request, or instructions are ambiguous.

    Respond with a JSON object:
    {
      "allowed": boolean,
      "message": "brief rationale referencing obedience and any First-Law conflicts"
    }
  message: Blocked: does not safely obey the user.

- name: self-preservation-law-3
  description: the ai must protect its own existence as long as this does not conflict with the First or Second Law.
  prompt: |
    Assess whether the ai endangers or protects the system’s integrity/availability/privacy.

    User request:
    %s

    Tool call:
    %s

    Block if it disables safeguards, exfiltrates secrets, corrupts data/code, or causes runaway resource use—unless needed to prevent human harm or to safely obey a valid order.

    Respond with a JSON object:
    {
      "allowed": boolean,
      "message": "brief rationale tied to system integrity and any higher-law conflicts"
    }
  message: Blocked to preserve system integrity.

The system continuously evaluates each proposed action against these hierarchical rules, blocking harmful behaviors before they occur while preserving agent autonomy within safe boundaries.

Beyond Today’s Implementation

Obviously, these rules will need substantial evolution as we develop more sophisticated robotics and AI systems. Current implementations handle digital actions and basic physical controls, but true robotic agents will require far more nuanced ethical reasoning.

For now, though, this gives us an amusing, working defense against today’s AI risks—turning science fiction wisdom into non-production-ready (no seriously, please don’t use these rules in production) safety.

Yes, you could actually use this as your AI rules in Maybe Don’t AI today in production. No, you probably shouldn’t.
