Click an element on your local dev site, write what should change, and your coding agent gets it — with the selector, DOM path, computed styles, React/Vue component chain, source-file hint and a cropped screenshot. No screenshot files piling up in your Downloads folder, no describing "the third button on the left".

Quick start

You need **Node 18+** and a Chromium browser (Chrome, Arc, Brave or Edge). The `claude` CLI is only needed for steps 3 and 4.

Everywhere below, replace `~/code/my-app` with **your own project** — the repo whose UI you want to annotate.

# 1. get it
git clone https://github.com/gowtham012/pinpoint
cd pinpoint/bridge && npm install

# 2. start the bridge, and leave it running.
#    This blocks the terminal — open a second one for everything below.
node cli.js --project ~/code/my-app

**3. Load the extension.** Chrome → `chrome://extensions` → **Developer mode** on → **Load unpacked** → pick the **`extension/`** folder (one level up from `bridge/`). The toolbar icon's dot turns green once it can see the bridge.

Annotating a page you opened as a `file://` URL? Chrome keeps that off by default. On `chrome://extensions`, open Pinpoint's **Details** and turn on **"Allow access to file URLs"**, then reload the page. Without it Pinpoint cannot appear on `file://` pages at all.

# 4. teach Claude Code about Pinpoint (once), from pinpoint/bridge
claude mcp add pinpoint -s user -- node "$PWD/cli.js" mcp
node cli.js install-hooks ~/code/my-app     #
