Save to Pocket (mini), a Chrome extension for https://getpocket.com
I think Pocket is great, but I don't like how their Chrome extension requires so many permissions. (It even makes use of those permissions to e.g. modify the Hacker News page. I appreciate this can be turned off via their settings but I'd prefer it didn't even have the capability.)
This extension is the minimal code to auth into Pocket and save URLs into it.
