Upload a video and let the agent schedule posts

The poster uploads a raw video to Claude and leaves it. After a few rounds of revisions together he trusts it enough that, once the edit is done, Claude Cowork downloads the video, opens his scheduling tool in a browser tab and schedules it to post on three platforms.

When the edited video is ready, open [SCHEDULING TOOL] and schedule it for [PLATFORMS] at [DATE AND TIME]. Use this caption: [CAPTION]. Before you hit schedule, show me a screenshot of each post's settings.

Our own prompt, written from what the source describes. We haven't run it ourselves. Text in [BRACKETS] is what you replace.

Turn your recipes into a recipe box that fills the cart

The poster gave Claude all of her recipes and it built a 'recipe box' page in Notion. When she picks what to cook, Claude Cowork takes control of her MacBook and adds the ingredients to her Walmart delivery cart. She mentions it in a reply to a teacher who uses an agent for similar errands. Keeping recipes in one place makes the grocery step repeatable: the agent works from the same ingredient lists every week instead of guessing from a recipe website. It's a good fit for Cowork because it works in the browser on your own computer, where you're already signed in to the store.

PromptHere are my recipes: [PASTE OR ATTACH]. Make a recipe box page in [NOTION OR A DOCUMENT] with one entry per...

Cowork can't reach your laptop files when it's closed

The poster points to Anthropic's help page: since new Claude Cowork tasks run in the cloud, they keep going after you close the Claude desktop app, but they can only read your connected local folders while that app is open on your computer. So a weekly report that depends on a spreadsheet on your laptop won't see it if the laptop is shut. His tip is to list where each input lives before you hand a job over, and to give a cloud copy for jobs that must run without your computer, noting that a copy goes out of date.

PromptBefore you start, list every file and app this task needs and where each one lives: my computer, the cloud or...

Cowork asks before each new website

A Claude Cowork user set it to research blog posts and had to approve each new site it wanted to read, including The New York Times, The Wall Street Journal, The Atlantic and The Washington Post. That stopped him from leaving it running in the background. Commenters suggest an allowed-sites list or an auto mode, which we haven't confirmed for Cowork.

PromptI want to research [TOPIC] for a blog post. Before you start, list every website you plan to read so I can...
