You paste a block of text into Claude Code. It collapses into [Pasted text #1 +24 lines]. You press Enter without seeing what actually made it in.
People worked around it by pressing Escape to cancel, reading the expanded text, then re-pasting in chunks. Or using Ctrl+G to open the system editor just to read back what they typed. One person wrote a VS Code extension that types text character by character to bypass the paste detection entirely.
Claude Code v2.1.116 fixes this. After text collapses, a tooltip shows up:
paste again to expandPress Cmd+V again and the block expands in place.

Ask Claude to update itself 😂
