# Hanzo Extension

Your browser, as a tool an agent can use.
It opens tabs, reads pages, and clicks things — in the session you are already signed into.

## How it works

The extension registers as a provider on the local fabric. Whatever can reach the fabric can then reach a tab.

### It uses your session

The agent drives the browser you are already signed into, so a page behind a login is a page it can read. Nothing has to be scraped from the outside.

### No port to open

The extension talks to the local Hanzo daemon through a native messaging host over a Unix socket. There is no WebSocket, no localhost port, and nothing else on the machine can dial in.

### Connected means registered

It only reports itself connected once the daemon lists it as a provider. An open pipe to a wedged process is the failure this replaced, and it is checked on every tick.

### Three browsers, one behaviour

Chrome, Firefox and Safari builds come out of the same source. The evaluate rule is shared, so the same snippet from a caller behaves identically in all three.

### Tabs are addressable

Each browser registers separately, so listing tabs asks the browser that is active — and naming a tab id from another browser's list is how you reach the other one.

### The rest of your tools, too

The same repo carries connectors for the software your work already lives in — documents, tickets, design files, mail, calendars — so an agent reaches them the same way it reaches a tab.

### Read a page as text

It hands back page content, console messages and network requests, which is what makes it useful for checking your own site rather than just browsing someone else's.

### Installs from a file

Load it unpacked in Chrome or as a temporary add-on in Firefox while you are working on it. The build produces all three targets in one command.

## What you would use it for

Mostly the work that only exists inside a browser window

### Check the change you just made

An agent that edited a page can open it, look at what rendered, and read the console — instead of telling you it thinks the fix worked.

### Behind a login

An internal dashboard, a vendor console, an admin panel. It runs in the session you already have, so there is no service account to provision for a one-off task.

### Debug the request, not the guess

Network requests and console messages come back as data. When a page misbehaves, the agent can read what the browser saw.

### The long boring form

Multi-step flows that exist only in a UI and have no API behind them. It fills them in and tells you where it got stuck.

## Not in a store yet

Its builds are not public, so there is nothing to install today. Hanzo Chat works in any browser now.
