dsh-browser
Browser automation for DeepSeek Harness: a Playwright-powered browser_* tool family so the agent can drive real web pages — fill forms, click through flows, scrape SPA content, and take screenshots it can then view with read_image.
Install
dsh plugin --profile <name> add dsh-browser
The plugin depends on playwright-core (bundled with the package) and needs a Chromium-based browser. It tries chromium, then chrome, then msedge channels automatically; if none is found:
npx playwright install chromium
or configure launch.executablePath / launch.channel in the plugin config.
Tools
| Tool | Purpose |
|---|---|
browser_open |
Open (or reuse) the browser, optionally navigate to a URL |
browser_navigate |
Navigate the current page and wait for load |
browser_click |
Click an element by CSS selector |
browser_type |
Type text into an input (optionally press Enter) |
browser_select |
Select option(s) in a <select> |
browser_screenshot |

browser_eval |

browser_get_text / browser_get_html |
Read visible text or outer HTML |
browser_wait |
Wait for slow pages / lazy content |
browser_close |

The browser persists across tool calls — open once, drive many times, close when done.

- Screenshots land in the calling agent's workspace so the model can read them with
read_image.
