Known limitations of the Flow alpha

Closed alpha. These limits are intentional in the current Builder Alpha.

Included

• Workflow design, validation, versioning, and simulation.
• Reviewable workflow ideas without a live execution claim.
• A prepared, separately gated Provider Preview contract; after release it may list models and send one explicit neutral request capped at 32 output tokens.

Not included

• Model inference or provider calls from a workflow.
• Repository, file, shell, or issue operations.
• External actions, unattended execution, or general availability.
• A published Flow consumer or npm next release for the prepared shared agent/contract candidate.

The Provider Preview is not currently available. When released, it will remain invite-only, separate from workflow execution, and dependent on login, entitlement, product-specific pairing, and a local grant for the exact provider. It does not make workflow inference available.

The prepared pairing authorization is deliberately short-lived: its challenge-bound browser grant expires after 60 seconds and the resulting local Flow session family after at most five minutes. Reauthorization is expected; there is no unattended or long-lived Flow Agent session in this Alpha contract.

Please keep production data, customer material, secrets, and confidential workflow contents out of alpha feedback. Follow the Flow changelog for public changes.
