A practical walkthrough of building a browser agent that automates license verification on a notoriously difficult government website (Texas TDLR). The setup uses BrowserBase to host a cloud browser agent, a Cloudflare Worker as middleware, and a Slack slash command as the user interface. The discovery phase used browse.sh CLI with GPT/Codex to identify page selectors, which were then hardcoded into deterministic JavaScript. The Cloudflare Worker handles Slack's 3-second response requirement by immediately acknowledging the command, then polling BrowserBase until results return, and posting structured license data back to Slack. The author suggests extending this with a nightly cron job to monitor all employee licenses automatically.
