Slack Strawberry45 Slack operations, starting with the messages
It reads every message your Slack account holds, drafts the changes that follow, and hands you a card for each one before a single message moves.
Open the message. Check it against something else. Write the change. Move to the next one. That is the Slack afternoon nobody can hand off, and a companion does the whole pass and gives you back the batch, with nothing landing on a message until you approve it.
What it can do is exactly what Slack exposes to an account you authorise and nothing beyond it: 45 operations, 22 reads and 23 writes. In practice that means it can upload a file, update a profile and update a message, and work across the messages, files and users.
The Slack API stops at Slack. A companion does not. The same run opens the customer's website, the supplier portal, the internal tool somebody built in 2019, because it is working the browser you are already signed into rather than calling in from outside it.
Can it verify slack signature on its own?
22 of the 45 operations are reads.
Your account, not a guess at it: a companion can verify a slack signature, build and send a block kit message and search, and the full list below is the whole list, with nothing inferred from Slack's documentation.
The messages are what most of this inventory is about, alongside the files. A companion can hold all 45 of these operations and forty open tabs in the same pass, which is how an afternoon of Slack admin becomes a queue you review.

What happens before it can upload file?
All 23 write operations wait for you.
A companion can upload a file, update a profile and update a message, and each one is staged on an approval card first: you see the message, the field and the new value before it lands in Slack.
Nothing in Slack is sent, changed or deleted on your behalf without that click, and a rejected card leaves the message exactly as it was. The gate is the same one on every surface, described at security.

Can it upload file on a schedule?
Yes.
Saved as a routine, the Slack messages pass runs at the hour you pick: the Monday sweep, the overnight refresh, the Friday check. Keep Awake holds the machine awake for the length of a run, so a scheduled pass finishes with the lid closed.
The operations playbook catalogues the other recurring shapes of the messages, the Slack messages sweep among them, and finished runs are published at real runs.
