# Browser agent with approval gates

> Automate a browser-only research or update task while preserving scoped credentials, replayable evidence, and approval before any irreversible action.

- Tools: Browser Use, Stagehand, Steel, FastMCP, Slack

## Quick answer

Browser agents can be powerful where no API exists, but they must be treated as a controlled operator: limit task scope, test on a sandbox, and require human approval for external impact.

## When to use it

- Competitor monitoring
- Portal data collection
- Admin updates
- Browser-only reporting

## Steps

1. **Define the permitted outcome** — Specify the target site, allowed pages, data fields, credentials, prohibited actions, stop conditions, and human approval owner. Tool: Slack. Expected output: An agent operating policy.
2. **Prototype the task** — Run the task from a natural-language objective on a non-production account and log each step, ambiguity, and failure mode. Tool: Browser Use. Expected output: A controlled prototype run.
3. **Make stable portions explicit** — Turn repeatable navigation and extraction into readable primitives with schemas so the team can inspect what the agent is expected to do. Tool: Stagehand. Expected output: A reviewable automation path.
4. **Use isolated browser sessions** — Run sessions with scoped profiles and preserve replayable evidence; do not share a broad personal browser profile. Tool: Steel. Expected output: An auditable browser session.
5. **Expose only needed tools** — Package narrow agent capabilities as typed tools, validate inputs and outputs, and insert confirmation before any write or submission step. Tool: FastMCP. Expected output: An approval-gated tool surface.

## Prompt templates

### Browser task policy

Write an operating policy for this browser agent task. Include allowed domains and pages, inputs, fields to collect, prohibited actions, credential scope, evidence to save, stop conditions, human approval gate, and incident owner. Task: [paste]

### Run review

Review this browser-agent run. Identify unexpected navigation, unverified data, authentication risk, incorrect extraction, attempted external action, and whether approval was correctly requested. Run log: [paste]

## Common mistakes

- Using a personal browser profile in unattended runs
- Letting the agent submit forms without approval
- Treating a successful click as a verified business outcome
