Developer builds browser agent that blocks write actions without explicit confirmation

A developer has built an open-source tool called Webhands to extract data from web portals and dashboards that lack usable APIs, using a headless browser to navigate them like a human user. The core safety feature distinguishes between read and write actions: reads proceed automatically, while any click flagged as a write action is blocked unless the request is resent with an explicit confirm flag. The safety check runs before the browser launches, ensuring no write step can partially execute before being caught. Extracted data is returned as structured JSON, either via CSS selectors or a natural-language prompt processed by Claude, along with a screenshot and action log. The project addresses a common automation risk where scraping tools can silently mutate production data if write and read actions are treated identically.
