createAB

// WHEN AGENTS USE THIS TOOL

AI agents use createAB to create or modify resources in Anytype. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

Without a policy, an AI agent could call createAB repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Anytype.

// RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access createAB gives an agent. Each links to the full case and the policy that stops it:

• Data exfiltration via tool chaining
• Prompt Injection via Tool Results
• Privilege escalation via admin-only tools
