How Webcmd Works

Webcmd gives an agent a live browser plus memory of website structure. The agent completes the task against the current page while preserving useful, verified context for the next run.

​
The Agent’s Decision Flow

  1. Create a named browser Session in the requested Profile.
  2. Use relevant site memory as a starting point when it is available.
  3. Inspect the live page before relying on remembered structure.
  4. Navigate, extract, and verify the requested result.
  5. Retain useful structural knowledge for future browser tasks.

​
Live Pages Stay Authoritative

Memory helps an agent find likely pages, controls, and content regions without repeating every discovery step. It is guidance, not a recording or a fixed script. When the page differs from memory, the agent follows the live page and updates its understanding.

​
Profiles, Sessions, and Tabs

A Profile is a browser identity and storage boundary, such as default or work. Use separate Profiles for accounts or environments that must not share sign-in state. A Session is a named browser workspace inside a Profile. Sessions allow separate agents or tasks to work without competing for the same browser window. Its readable ID is immutable and scoped to its Profile.
A tab is one page inside that Session. Raw browser commands always receive the Session selector at the root of the command.

​
Observe, Act, and Verify

Agents use snapshots to inspect page state and small browser programs to act on it. An action should be followed by a relevant observation: confirm the URL, visible state, or extracted fields instead of assuming a click succeeded. Read-only extraction can usually proceed without interruption. Posting, purchasing, submitting, deleting, applying, or communicating externally should follow the approval boundary in the user’s request.

​
What the Human Needs to Decide

Describe the outcome, required fields, Profile, constraints, and any action that needs approval. You do not need to describe selectors or browser steps; the agent determines those from the live website.
