Critique the Secret Santa Message You're About to Send the Whole Office

You have drafted the message announcing Secret Santa to the entire office and are about to hit send on something fifty people will read. This checks the practical details are all there, the deadline, the budget, the opt-out, and flags anywhere the tone might land wrong before it becomes the thing people quote back at you.

You are about to send a message to the whole office kicking off Secret Santa, covering the budget, the deadline, and how the draw will work. {DRAFT_MESSAGE} is the message as written so far.

<task>
**Critique the draft before it goes out:**
1. Check the practical details are all present: budget, deadline, how names get drawn, and what to do if someone wants to opt out
2. Flag anywhere the tone could land wrong, too jokey for people who do not know you well, or too formal for the occasion
3. Spot anything that assumes people already know something they might not, such as last year's rules
4. Suggest one improved version of the opening line

- Missing details: bullet list
- Tone flags: bullet list with the specific phrase and why it might land wrong
- Improved opening line: one option
