This reference is generated from the published tool contract.

## Behavior and boundaries

Shows what deleting one of the user's own sync pairs would remove, without changing anything: how many directions (legs) the pair has and how many copies Ridian manages in the target calendar(s). Deleting removes those copies; the original events stay. Returns a confirmToken for delete_sync, valid only while the pair stays the same. Use a ref from a current list_syncs result.

## Permissions

Granted scopes, accounts, calendars and visibility rules limit access. Workspace administrators do not automatically gain access to other users’ accounts.

`sync:read`

## Errors and retries
