Threads tools

`threads_open`

Go to a screen in Threads on the iPhone by code, with no taps from you (your feed, activity, a profile, search, a post’s link). For an act it names the control and never taps it. Acts on the device. Arguments

Name	Type	Default	Description
`where`	string	required	Where to go in Threads: home, activity, profile, search, post, like, follow, with a name, @user, words or a link where one is needed (“thread Sam Lee”, “profile @nasa”). An act’s place (like, follow) names its control and never taps it. At most 200 characters.
`device`	string	see description	The device’s name or id from `list_devices` (or leave it out for the server’s default device).
`run_id`	string		A check’s run id from `verify_start`, to drive its device instead.

Example

tools/call params

{"name": "threads_open", "arguments": {"where": "home"}}

Returns A line naming the screen it reached. structuredContent has screen, title, confidence, how and steps. When where names a control, the line says where the control is, and structuredContent has control, with its label, role and where; it never taps it.
