cat error.log | claude: the log goes straight in, no copy-paste, no truncation, no mangled formatting.

Prefix a message with ! and the shell command runs with its output landing in context, which is faster than describing what you saw.

And in plan mode (where Claude proposes a plan before touching any files), Ctrl+G opens that plan in your own editor so you can rewrite it properly before it proceeds, instead of trying to correct it conversationally.

None of these are impressive. All of them remove a step where information gets lossy or you lose your place, which is where most friction actually lives.
