How to add resume proof receipts to browser AI agents

Browser agents often pause with cached page evidence, then resume after the page, account, cart, or approval has changed. Resume proof receipts make the agent verify old context before it clicks, submits, books, buys, or publishes.

Browser AI agent resume proof receipt workflow

The browser resume moment needs proof.

A browser AI agent can be technically on the right page and still be using stale evidence. The receipt connects cached observations, refreshed page state, approval scope, and next action.

Start with a reference packet

Before the browser agent pauses, save the evidence it will rely on later: URL, page title, active account, selected item, price, visible fields, screenshot, approval text, and expected next action.

  • Capture the exact form values and destination.
  • Store the user approval that allowed the next step.
  • Record the reason the agent is waiting or handing off.

What the receipt should show

Old value, current value, drift classification, approval status, live-state validation, and the route: continue, refresh, ask again, or stop.

A browser agent should never resume from cached evidence without proving the page still matches.

A six-step receipt workflow.

This workflow fits browser agents that pause for user review, rate limits, external confirmation, or scheduled continuation.

Capture browser reference state

Capture browser state

Save URL, account, selected object, page fields, visible price, screenshot, and planned action.

Refresh browser evidence

Refresh evidence

Reload or revisit the source before relying on cached page observations.

Compare browser state

Compare values

Name every changed field and classify whether it is harmless or material.

Validate approval scope

Validate approval

Confirm the prior approval still applies to the current page, amount, recipient, and destination.

Validate live action state

Validate live action state

Check active account, form state, permissions, and target before clicking or submitting.

Generate browser proof receipt

Generate the receipt

Show the result to the user and store it for the next agent run.

Implementation checklist.

Use these rules in the browser agent prompt and orchestration layer.

Never trust cached evidence alone.

Refresh the source before action.

Never reuse stale approval.

Ask again when price, recipient, page, or destination changes.

Always validate the active account.

Browser agents often fail by acting in the wrong session.

Always store the receipt.

The next run should read the proof without replaying the chat.

FAQ

Short answers for teams adding receipts to browser agents.

When should a browser agent generate a receipt?

Before any delayed click, form submission, purchase, schedule change, or publish action.

Does this replace screenshots?

No. Screenshots are evidence inside the receipt, not the receipt itself.

What is material drift?

Any change to account, price, item, recipient, destination, form state, or approved output.

What should happen when drift appears?

The agent should stop, explain the mismatch, refresh evidence, and ask for approval again.

Make cached browser work provable.

Resume proof receipts help browser AI agents continue only when context still matches.
