dsh-browser-runtime

Give an existing DSH Agent real browser capabilities without bolting on a separate orchestration layer. dsh-browser-runtime ships as a single bundle that mounts a Chromium runtime, a Playwright Provider, eighteen browser_* tools, and usage guidance onto the Agent you already have—covering navigation, clicking, form filling, scrolling, waiting, screenshots, and structured extraction.

Rather than a loose set of Playwright calls, the runtime owns Agent isolation, browser lifecycle, serialized operations, stale-reference checks, resumable checkpoints, before-and-after transition evidence, and a credential-safe fill channel. Each Agent object gets its own BrowserContext so parallel Agents never share cookies, navigation state, or element refs. Observations are ranked into tiers—form controls first, then pagination, site navigation, record titles—so the model references fresh refs from the latest observation instead of hand-writing CSS selectors or executing JavaScript.

Built for developers who need an Agent that reads dynamic pages, fills forms, extracts lists or tables, saves screenshots, or runs multiple browser tasks in parallel with fully isolated state. The Provider interface is replaceable, so swapping in another browser engine later keeps the Agent-facing contract stable.
