Teach Claude your club email rules once, then let anyone on staff run them

You are helping me write a reusable instructions document that I will save into a Claude Project, so Claude follows it every time my team drafts a specific piece of writing.

My business: [winery / brewery / distillery / wine and spirits shop / distributor] in [region].
The recurring task I want to standardize: [e.g., wine club shipment announcement email / weekly distributor account recap / new arrivals shelf talker / taproom release post].
Who does it today: [role], about [number] times a month.
My brand voice in my own words: [e.g., warm, plainspoken, zero cork-sniffing, first person from the winemaker].
Things I always fix when I edit someone else's draft: [list 3 to 5, e.g., too many tasting notes, no clear ship date, subject line over 50 characters, no reason to open the bottle].
Hard rules: [e.g., always include pickup window, never use "notes of," always one call to action, no health claims].
Reference material I will attach to the project: [e.g., three past emails that sold well, our price list, wine specs].

Produce the instructions document with these sections, written as direct instructions to the AI, not as advice to me:
1. Purpose: one sentence on what this produces.
2. Inputs the user must supply each time (list them as fields to fill in).
3. Voice and style rules, stated as do and do not.
4. Required structure of the output, section by section, with word counts.
5. A worked example using a plausible [wine / beer / spirit] from my region.
6. A final checklist the AI runs on its own draft before returning it.

Then ask me up to five questions about anything you had to guess at, and tell me which of my "hard rules" are too vague to follow consistently and how to tighten them.
