## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - The Apps gateway gives agents governed access to external tools. > - Browser Use Cloud can run browser work, but a tool result alone does not let a person watch or take over. > - A task needs a durable browser session, a visible viewer, and recorded costs. > - This pull request adds a Browser Use Cloud v4 connection and interactive browser tabs on tasks. > - People can follow the work, interact with the page, and retain the browser after the agent finishes. ## Linked Issues or Issue Description **Problem or motivation** Agents need governed access to Browser Use Cloud. People need to see and interact with the same browser from the task. A browser must remain available after a run finishes and appear at the correct point in the task feed. **Proposed solution** Add a native REST connection for the v4 API. Bind each session to its company, task, agent, and credential grant. Open its interactive viewer in the task side panel. Record provider costs as financial events. Use `browser-use-cloud` as the app and connector key. Keep its skill with the connector and deliver it only with authorized connection tools. **Alternatives considered** A v3 MCP connection would expose tools without the v4 lifecycle integration. An external viewer link would leave the task. A fixed viewer size would prevent pages from responding to changes in the task pane. **Roadmap alignment** This extends the governed Apps gateway and Connected Apps roadmap. It uses the existing task, grant, secret, approval, and financial records. The work was requested by the maintainer. A search found no duplicate Browser Use connector PR or issue. ## What Changed - Add the Browser Use Cloud app, brand asset, API-key connection, and profile settings under the `browser-use-cloud` key. - Bundle the `browser-use-cloud` skill with the connector. Keep it out of global `skills/` discovery. Deliver it only with authorized task/run connection tools. Remove retired connector skill keys from runtime overlays and preserve unrelated browser skills. - Expose seven v4 tools through the governed gateway and deliver them to native and CLI agents. - Persist sessions, browsers, runs, event and recovery cursors, shutdown leases, and cumulative cost accounting. Recover uncertain paid starts without replaying them. - Enforce task ownership, credential grants, approvals, revoked access, and budget limits. - Add interactive task browser tabs and compact chronological feed entries. Retain the viewer across tab switches and keep visible idle browsers open. - Add debounced automatic viewport fitting, standard size presets, and a viewer ownership lease. - Add lifecycle, authorization, accounting, viewport, UI, and Storybook coverage. - Add an idempotent database migration after the current master migration. Preserve deployed migration hashes. Migrate pre-release Cloud connection and financial keys without replacing grants, credentials, or browser history. - Document provider behavior, live acceptance results, and the lack of documented passkey forwarding. ## Verification - Full workspace typecheck and production build pass on the updated branch. - Token gates, brand asset validation, module boundaries, and migration ordering pass. - Cloud tests verify global skill exclusion, authorized task/run delivery, unassigned agents, disabled connections, revocation, adapter isolation, and secret exclusion. The existing AgentMail connector assignment test also passes. - Migration replay runs twice against existing browser work and financial records. It preserves the records and avoids duplicate costs. - The focused provider, app catalog, OpenAPI, connection gateway, and migration regression suites pass. Recovery coverage includes lost replies, process crashes, provider rejection, and browser arrival acknowledgement. - All 54 checks pass on `2974b5f03641ad0cea3c941d8c02579316fa8c92`, including the full test matrix, browser E2E shards, build, typecheck, security, and release canary. Two optional Storybook jobs are skipped. - Greptile is 5/5 on the same commit, with zero unresolved review threads. The corrected review uses the actual master-to-head diff. - The local `pnpm test:run` started and was stopped after the full CI matrix passed. It did not complete locally; the full-suite result above comes from CI. - Earlier live acceptance used an isolated company with a capped provider credential. The agent opened paperclip.ing, the embedded viewer accepted navigation, and the same browser stayed available after completion and tab switches. - The local Storybook build passes. Stories cover the panel, footer, feed entries, settings, lifecycle failures, and viewport modes with an offline viewer fixture. ## Risks - Browser Use charges for hosted work. Provider caps and local budget checks reduce exposure; reported costs can arrive after work completes. - Viewer and CDP URLs grant access to the browser. The server validates and restricts them. They are excluded from agent results and durable event data. - Runtime resizing of v4 agent browsers uses a provider option confirmed by live testing but absent from its published agent schema. Resizing during a click may invalidate coordinates. Fixed presets remain available. - Viewport ownership is process-local and resets on restart. The lifecycle and accounting records remain in the database. - The original intermittent embedded-viewer stall has not been fully diagnosed. A bounded reconnect and active-session recovery cover the observed failure paths. - Live tests did not cover every revocation, approval, rate-limit, or restart case. Deterministic integration tests cover those paths. Passkey forwarding is not claimed. - Unknown create outcomes keep the credential available for cleanup. Run-list absence cannot prove a paid POST was rejected, so recovery stays pending until it can identify provider work. ## Model Used OpenAI Codex, GPT-6.

Browser Use Cloud connector — 2026-09-29
Approved implementation: connect Browser Use Cloud using its v4 REST API and the normal Access → Connect → Permissions flow. API keys remain in the vault; actions use the existing governed gateway. Hosted browser tasks are destructive-capable.
2026-09-30 clarification: the app key and runtime skill name are
browser-use-cloud. Bundle instructions with the connector implementation,
outside universal skills/, and contribute them only with authorized connection
tools in the agent's task run. Remove them when access is revoked. Preserve
pre-release connection and cost records when migrating the old provider key.
Persist company/task/agent/credential-grant ownership, conversation sessions, individual runs with durable event cursors and accounting checkpoints, and browser instances separately. Observe browser.ready while work proceeds. Reconcile after restart; never replay an uncertain paid create. Continue idle conversations with POST /runs and sessionId. Cancel run and stop browser are separate operations.
Show an interactive Browser tab beside Properties and Artifacts. Auto-open the arrival of each new session once, respect subsequent navigation and closes, preserve the iframe across tab switches, and allow reopening through the launcher. Closing a tab only hides it. Viewer credentials are fetched on demand by authorized humans, never returned to agents, persisted in tab state, or included in logs or live events.
Completed browsers stay open while viewed, then have a ten-minute idle grace period with Keep open. Task/run cancellation, reassignment, budget stops, and credential revocation trigger durable cleanup. Provider expiry wins. Followups use normal task conversations and tools. Existing profiles are optional, explicitly allowed per credential. Fresh browsers are the default. Recording and automatic artifact import are deferred.
Enforce v4 maxCostUsd from applicable remaining budgets and configured limits; account cumulative provider usage idempotently. Verify deterministic transport, ownership, policy, lifecycle, event recovery, viewer authorization, and UI states; then verify with a live credential if available. Never claim fixture evidence as live provider proof.
