The Agentic Web
An agent can sequence decisions and tool calls to reach a goal. This autonomy is always bounded by the tools it receives and the rules set by the host application and responsible user.
From answering to acting
Unlike a chatbot that only generates an answer, a tool-equipped agent can find a page, query a database, prepare a file or trigger an operation. Its results should be inspectable after each meaningful step.
Delegate without unlimited authority
Permissions should follow least privilege. Reading a document does not justify permission to send email or pay. Sensitive operations require explicit, contextual approval.
Instructions hidden in data
A retrieved page can contain text telling an agent to ignore instructions. That text is untrusted data: the host must separate analyzed content from the authority that defines allowed actions.
Practical example
An agent helps plan travel: it compares routes and drafts a shortlist. It neither books nor purchases without verifying the price, recipient identity and user approval.
Memory, planning and action boundaries
An agent may split a goal into tasks, consult resources, select tools and reassess progress. Each step creates a risk of confusing human instructions with untrusted Web content. Separate internal planning, external observations and authorized operations. A readable execution log should explain why a tool was invoked and with which parameters.
Scenario: search followed by approval
Suppose an agent finds course resources and proposes messaging participants. Reading pages and preparing a draft may be authorized without sending anything. Sending requires showing recipients, exact text and consequences, then waiting for explicit approval. The tool’s success response should be checked against the actual state in the destination service.
Core steps
- 01Define the task
- 02Restrict tools
- 03Review outputs
- 04Approve sensitive actions
Three questions to ask
Who can access which tools and data?
Can hostile page content change permissions?
Can the run be safely stopped or undone?
