When an AI agent needs a credential, have the user paste to clipboard (Cmd+C) and pipe via pbpaste rather than sending the token through the chat message. This keeps the token out of the session's message log entirely. When tokens DO pass through chat, expect redaction artifacts: the literal string "***" can land in bash heredocs, Python scripts, and file contents, breaking operations silently. The fix is to read the token via clipboard pipe or environment variable, never write it to disk.
