About this plugin
Every time an agent needs to open a web page for verification, a system browser window pops up and covers the conversation pane. computer_screenshot returns a blank frame, the workflow stalls, and you end up shuffling between browser and chat just to confirm what the agent sees.
dsh-web-verify-panel folds the page-opening request into the DSH sidebar. It exposes a web_verify_open(url, title?) tool that renders the target page inside a sandboxed iframe and returns the page area as a rect you can feed directly into computer_screenshot's region parameter. The panel auto-expands to roughly 60 percent of the viewport (capped at 1600 px) and retracts after 60 seconds. Because rendering happens in a sandbox, the page never shares your system browser's session, and tabs across sessions stay isolated.
If you run DSH on Windows desktop and your agent frequently opens pages for content checks or screenshot comparisons, this plugin closes the loop in a single window without any system pop-up. macOS, Linux, and the web build also support opening and viewing; screenshot capture depends on whether your platform provides a separate computer-use implementation.
Use Cases
- Let the agent open and screenshot a page inside the sidebar without spawning a system browser window
- Use the rect returned by web_verify_open directly as the region parameter for computer_screenshot
- Run multiple sessions in parallel with each tab isolated in a sandboxed iframe, no shared login state
Best For
- DSH users on Windows desktop who frequently ask the agent to open pages for content checks or screenshot comparison
- Developers who want a single-window workflow without being interrupted by system browser pop-ups
- Teams that need session-level page isolation and do not want to share system browser login state
