Agent repliedFound it: the footer covers the last 40px of the form. Fixed; reload to check.It keeps everything you already know about screenshots, and adds one thing: a way to hand the right one to your agent with a sentence attached.
Press ⇧⌘4 and pick an area, as always. The shot saves to your Desktop and slides into the corner.
Click a shot and it opens in the middle of your screen with a note box. Type a line, press Return.
Each shot arrives in your agent’s session while it works or waits, and it looks at the image itself.
When your agent replies, your Mac tells you. Reply straight from the notification, or open the conversation.
Pin the corner stack to keep collecting. Right after a shot, ⇧⌘R turns it into a message and ⇧⌘C copies it. Or drag it into anything that takes a file.
Shots are encrypted on your Mac before they leave it, and signed so your agent knows they came from you.
Spotted it on your phone? Share the screenshot to Screenshot.fm, add a note, and it joins the same conversation as your Mac.
Open Settings and choose Connect Claude Code, for the terminal and the Claude desktop app’s Code tab. For the desktop app’s Chat tab, choose Add Extension.
Then paste your agent link into Claude. In Claude Code, every shot you send turns up with your note while Claude works or waits; in a chat, Claude sees new shots each time you write.

Moving the padding into a variable. ⏺ Update(src/Footer.css) — 3 lines
Only the shortcut you choose. Pick ⇧⌘4 and Screenshot.fm takes it over while it runs; quit and macOS gets it back. Shots still save to your Desktop, or any folder you pick.
No. Shots only go when you click one and press Send, or when you turn on “Prompt for agent notes on all shots”.
Your agent, and any device you’ve paired. They travel over wwwave, encrypted on your Mac with a key that lives only in your session’s links, so the service in between can’t open them.
