# File sync # File sync Providers Builds the scheduled workflow that copies a configured storage location into an external partner's file share: the infrastructure, a planning and cost gate, per-file workers, an aggregate, and the credential and configuration handling around them. - **Used when** — When files have to leave internal storage for a partner's share on a schedule, and the run has to be safe to repeat. - **Loads first** - The batch-workflow skill, for the distributed shape. - The inbound-transfer skill, where the destination is a plain file-transfer endpoint, with the direction reversed. - The continuous-integration skill, for the per-environment deployment path. - **Returns** - The chosen destination provider and its authentication flow, confirmed with the requester. - The repository layout — infrastructure, handlers, provider adapters, tests. - The parameter and secret schema, with the exact commands per environment. - The runtime contract: the invocation event, the manifest, and the summary. - The permissions actually granted, least-privilege. - The deployment files added, and how the target environment is wired. - A verification log covering a dry run, a single-file transfer, an idempotent rerun, a change-detection rerun and the schedule. - The inputs still owed, and rollback notes for both code and configuration. ## Others in Providers - Marketing stack - Roster workflow - Send lifecycle
