Since you're canon familiar I'm not doing a Fancy Write-Up for this, but here's a list of all his canon shenanigans for reference:
- Stole ripe plums to leave on a windowsill, so they'd attract flies that will feed the spiders whose webs can be used for medicinal purposes (iirc he actually told the woman who mentions this about how the webs can be used, but she can't remember who told her since, lol) - Stole a bunch of men's daggers and hid them in a barrel, because tensions were high and he was preventing them from badly hurting each other over any arguments - Stole a wheel of cheese and crushed mint; the cheese to attract mice in the kitchens which attract the cats, which the mint then makes them "dance and play" which cheered up the head cook so she wouldn't take her bad mood out on her staff anymore - Stole a bag of turnips and threw them into a fire so the smell would remind a dying man of his mother's turnip stew as he died - Stole bread to toss on the battlements to draw birds, because a badly wounded soldier says he won't die until winter comes, and it's not winter until the birds leave
He no doubt does other things here and there (there's the implication he puts honey in Leliana's wine, he puts a wooden duck on Dorian's bed, Scout Harding said he had an armful of chickens once??? does Cole ever help without stealing something, We Just Don't Know), but despite the fact none of these people can see him or will remember him if they do (Dorian asking about the duck aside), he is genuinely happy to know that he's done something that helped people, even if it's in seemingly odd or trivial ways that some may not even interpret as helping. That's fine though, so long as he can sense that someone's happier or a pain of theirs has been eased, or he's prevented people from getting hurt or hurting others. He never needs or wants any acknowledgment or recognition for his actions.
Akechi can also get a feel for what Cole's "mind reading" & empathy is like through this, both in how it just naturally flows through him like any other bodily sense, and how he uses that to listen for what emotional hurts he can help with rather than judge people's thoughts and memories. Feel free to assume Akechi can glean other tidbits of information through what he hears from people's thoughts in the memories as well, e.g. what happened to Haven and general stuff about his world and the Inquisition.

- Stole a wheel of cheese and crushed mint; the cheese to attract mice in the kitchens which attract the cats, which the mint then makes them "dance and play" which cheered up the head cook so she wouldn't take her bad mood out on her staff anymore
- Stole a bag of turnips and threw them into a fire so the smell would remind a dying man of his mother's turnip stew as he died
- Stole bread to toss on the battlements to draw birds, because a badly wounded soldier says he won't die until winter comes, and it's not winter until the birds leave
