Unpacked Chromium MV3 build of the Agent Beacon browser collector (browser-extension/). The same archive loads in Chrome, Edge, Brave, Opera, Vivaldi and Arc; CI tests it in Chromium and Edge.
Install: download and unzip, then open the browser's extensions page (chrome://extensions, edge://extensions, brave://extensions, ...) -> Developer mode -> Load unpacked -> select the unzipped folder.
Requires a running Beacon endpoint: the extension POSTs OTLP GenAI logs to http://127.0.0.1:4318/v1/logs.
Retention defaults to full, meaning complete prompt and response text from claude.ai and chatgpt.com is written to the local runtime log. Change it in the extension's options page before enabling it on a machine where you use those sites personally.
The archive is unsigned. Verify it against the .sha256 published beside it:
shasum -a 256 -c agent-beacon-browser-extension-0.1.0-chrome.zip.sha256
