Agentic AI: designing the tool allowlist that bounds the agent
An agent can only do what its tools allow. Design the tool surface to make safe actions easy and dangerous ones impossible.
11 min · Reviewed 2026
The premise
Agent safety lives at the tool boundary, not the prompt. If your agent has a delete_user tool, it will eventually call it. The right design exposes only the verbs your use case requires.
What AI does well here
Call the tools you provide with parameters drawn from context
Stop calling tools that error consistently
Compose multi-step plans across the available verbs
What AI cannot do
Restrain itself from dangerous tools by policy alone
Distinguish a tool used wisely from one used recklessly
Audit its own tool history without your help
End-of-lesson check
