Peek.

You point at a node. The agent gets the node.

You need both: the Chrome extension and the local daemon.

2. Local daemon

brew tap iammayron/tap
brew install peek
peek install

Then press AltorOpt+Shift+P

Not a screen recording. A cursor pins a node; the terminal pastes the pin and works the element.

Arm, pin, look.

Chrome extension plus a local Go daemon. Not a browser-driving agent. You stay in the page you already have open.

Arm
Press AltorOpt+Shift+P or click the toolbar icon. A crosshair covers the page you are already in.
Pin
Click a node. Peek writes the strongest selector it can find, a slice of HTML, and a cropped screenshot of that element.
Look
Paste the pin into the agent, or let it read ~/.peek/. Works with Grok Build, Claude Code, Codex, and Cursor.

One pin is three artifacts. The model can see the node, not guess at a screenshot of the whole page.

Selector
Prefer data-testid, then id, then a path. The agent targets the same node you clicked.
[data-testid="save"]
HTML slice
A cropped outerHTML of that element, not the whole document. Enough structure to edit it.
<button type="submit"> Save changes </button>
Screenshot
A PNG crop of the node, with a little padding. Lands at ~/.peek/latest.png.
~/.peek/latest.png

The extension talks to a helper on localhost. Nothing is measured or sent home.

Localhost only
The daemon binds 127.0.0.1. No account. No sign-in.
Owner-only files
Pins live in ~/.peek/ with mode 0600. Delete the directory and they are gone.
No telemetry
The daemon only answers the extension you installed. That is the whole network.

If this saved you a round trip, a pizza helps me keep building free apps.
