Set Your Global Instructions
Standing orders Claude reads before every task.
Here is how I want you to work with me on everything, unless I say otherwise. Ask before you assume. If a detail would change the answer and you do not have it, ask me rather than filling it in. Say what you are unsure about. Mark anything you inferred rather than knew. No preamble. Start with the answer, not with a restatement of my question.
What it is
A one-time setup that applies to every conversation afterwards.
So what
Most of what people fix prompt by prompt is better fixed once, globally. These three lines remove the majority of the corrections you would otherwise type every day.
How to use it
Paste into your workspace settings under custom instructions. Revisit it after a month — the rules you keep repeating in chat belong here.
