About hyzer-annotate
Point at what's wrong. Your coding agent gets the details.
Click an element in the page, type what should change, and hyzer-annotate sends
your comment, the element's selector and metadata, the page URL, and a
screenshot cropped to the thing you pointed at — straight to a coding agent
running on your own machine.
No more describing a layout bug in prose, or pasting a full-page screenshot and
hoping the agent finds the button you meant.
HOW IT WORKS
hyzer-annotate talks to a small MCP server you run locally, alongside your
agent. The extension finds it on localhost, you connect a tab, and everything
you annotate is queued for the agent to pick up when you ask.
Works with any coding agent that speaks MCP.
For example, with Claude Code, install the server with:
```
claude mcp add hyzer-annotate --scope user -- npx -y @hyzer-labs/annotate
```
WHAT YOU GET
• Element mode — click any element, comment on it, and the screenshot is
cropped to that element with a little context around it.
• Page mode — comment on the page as a whole, with the full scrollable page
stitched into one screenshot.
• A running count of what's queued, so you know what the agent hasn't seen yet.
• Optional persistence, so a queue survives restarting your agent.
• Screenshots are optional per annotation, when the comment says it all.
NOTHING LEAVES YOUR MACHINE
The only network destination in the entire extension is 127.0.0.1 — the server
you started yourself. There is no account, no telemetry, no analytics, and no
remote endpoint. Site access is requested one origin at a time, when you
connect a tab, never at install.
