DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.121

iTerm2 Clipboard Integration

What

Claude Code now automatically enables the "Applications in terminal may access clipboard" setting in iTerm2, making the /copy command work without manual configuration.

Usage
# Run /terminal-setup in iTerm2 — it now specifically enables clipboard access
/terminal-setup

# Or just use /copy — Claude will prompt to enable clipboard access if needed
Details
  • Detects iTerm2 terminal via TERM_PROGRAM or LC_TERMINAL environment variables
  • Writes AllowClipboardAccess preference via defaults write on macOS
  • Reports success and reminds user to restart iTerm2
  • When connected from iTerm2 via SSH, shows guidance about reaching local clipboard
  • Shift+Enter is noted as natively supported in iTerm2 (no configuration needed)
  • /terminal-setup description dynamically changes to "Enable iTerm2 clipboard access for /copy" in iTerm2
Evidence

iTerm2 clipboard enablement (search for "AllowClipboardAccess", "iTerm2 clipboard access already enabled")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
