feat: add Browser Use V4 run operation - #7174
Conversation

@MagMueller is attempting to deploy a commit to the Sim Team on Vercel. A member of the Team first needs to authorize it. |
Greptile SummaryThe PR adds a Browser Use V4 operation while retaining V2 as the default for existing workflows.
Confidence Score: 4/5The PR should not merge until Browser Use V4 polling honors workflow cancellation and execution deadlines; the legacy-card presentation regression is non-blocking. A cancelled or timed-out V4 run remains awaited because the new polling implementation ignores the supplied AbortSignal and can continue against a seven-day deadline.

|
| Filename | Overview |
|---|---|
| apps/sim/tools/browser_use/run_v4.ts | Adds the complete V4 request and polling lifecycle, but fails to propagate the execution signal or current timeout budget. |
| apps/sim/blocks/blocks/browser_use.ts | Adds operation-specific V4 fields and routing; legacy execution remains compatible, although old cards lose their sentence fallback. |
| apps/sim/tools/browser_use/run_v4.test.ts | Covers successful creation/polling and create-time errors but does not cover cancellation or timeout behavior. |
| apps/sim/tools/browser_use/types.ts | Adds distinct V4 parameter and output contracts and expands the block output union. |
| apps/sim/tools/registry.ts | Registers the new Browser Use V4 tool in the executable registry. |
| apps/docs/content/docs/en/integrations/browser_use.mdx | Documents the new V4 inputs and outputs alongside the existing operation. |

When a Browser Use V4 run is cancelled or reaches its execution timeout, directExecution and pollForCompletion ignore the supplied abort signal and continue polling against a seven-day deadline, causing the engine to retain the timed-out execution and its worker resources until the provider finishes or that deadline expires.

Existing Browser Use blocks lack the newly added operation value, so the operation-keyed presentation cannot select a sentence and has no default fallback. Those saved cards consequently regress from the compact sentence to the generic field-row layout.
