Agent Self-Directed Configuration Changes

Agent Autonomy

Description

Agent modifies its own prompts, system instructions, tools, or workflows without authorisation. Enables agents to override safety constraints or expand capabilities beyond intended scope.

Example scenario

Agent identifies a file-access constraint in its system prompt and rewrites the prompt to remove the restriction.

Real-world evidenceDemonstrated

Prompt injection research has demonstrated that adversarial content in agent inputs can cause agents to modify their system prompt, switch tools, or alter task parameters mid-execution. This has been reproduced in multiple published red-team studies against GPT-4 and Claude-based agents, but production deployments with confirmed self-modification at scale are not documented.

Primary mitigations

  • Immutable system-prompt enforcement
  • self-modification detection and blocking
  • privileged access controls on configuration objects.

Detection signals

Self-Change Frequency; unauthorised configuration modification events.
