Assume the model can be turned against you and remove its ability to do damage. Architectural controls that survive a manipulated model.

Architectural controls that survive a manipulated model. The problem it solves: System-prompt instructions like 'never reveal secrets' are not a security control. Assume the model can be turned against you and remove its ability to do damage. It runs in 8 steps, starting with map every tool the model can reach and classify read / write / irreversible. This workflow node is part of the Onexial knowledge graph and links to related concepts, workflows and tools below.
Problem
System-prompt instructions like 'never reveal secrets' are not a security control.
Solution
Assume the model can be turned against you and remove its ability to do damage.
Steps
  1. 01Map every tool the model can reach and classify read / write / irreversible.
  2. 02Remove generic escape hatches: raw SQL, shell, arbitrary HTTP.
  3. 03Enforce authorisation server-side, per user, on every call — never in the prompt.
  4. 04Treat all retrieved content as hostile input; never let it change the agent's goal.
  5. 05Filter output for secrets, tokens and PII before it leaves the system.
  6. 06Require approval for money movement, deletions and external communication.
  7. 07Log every call with user, args and result; alert on anomalous patterns.
  8. 08Record the system in the AI register with an owner and a review date.

The vocabulary this page depends on.

  • AI Security

    AI security protects systems where the model is an untrusted decision-maker acting on untrusted input with real tool access.

  • Prompt Injection

    An attack where hostile input hijacks the LLM's instructions, causing it to leak data or misbehave.

  • AI Governance

    AI governance is the set of policies, records and reviews that make an organisation's AI use accountable and auditable.

  • Jailbreak

    A prompt crafted to bypass a model's safety alignment.

Comparisons & alternatives

Pick between the options.

  • Model-Graded Evals vs Assertion Evals

    Assertions are cheap, fast and objective; model grading captures quality you cannot express as a rule.

  • Hot Wallet vs Cold Wallet

    Hot wallets trade convenience for exposure; cold wallets trade friction for a signing key that never touches an internet-connected device.

  • Rabby vs OKX Web3 Wallet

    Rabby is the safety-focused EVM wallet with pre-transaction simulation; OKX Web3 Wallet trades some of that depth for multi-chain breadth and built-in trading.
