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 v2.1.166

--cloud replaces --remote for cloud sessions

What

The flag to create or attach to cloud sessions has been renamed from --remote to --cloud. The old --remote continues to work as a deprecated alias so existing scripts don't break.

Usage
# Start a new cloud session
claude --cloud "your task description"

# Attach to an existing session by ID
claude --cloud <session-id>

# Attach by claude.ai/code URL
claude --cloud https://claude.ai/code/...
Details
  • All error messages, help text, and usage examples now use --cloud
  • --remote is still accepted but shows in the --help output as "Deprecated alias for --cloud"
  • The --bg conflict message has been updated: "Use claude --cloud '<task>' directly to start a cloud session"
  • Sessions started with claude --cloud display the correct browser link message
Evidence

CLI flag rename — all error strings updated (search for "Error: --cloud cannot be combined with")

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