Summary  
This chapter covers designing a templating system that defines reusable message structures with clearly named placeholders, enabling dynamic content substitution without rewriting messages from scratch.  

General domain of usage  
Automating routine status update and announcement messages.

Not every message needs to be written from scratch.
 
Some categories of message repeat constantly: the same kind of status update, the same kind of announcement, week after week. Writing a fresh message each time is wasted effort. A **template** captures the reusable structure of the message, with **placeholders** for the details that change:
* The project or topic name;
* The date or deadline;
* The specific decision or update.

A small library of two or three well-made templates, covering your most common categories, can cover a large share of routine communication once combined with the extracted key points from earlier.

> ## Task
> Ask Claude to build templates for your most frequent message categories, with clear placeholders marking exactly what needs to be filled in each time.
>
> > <b>Build message templates for my three most common categories, with placeholders for the details that change each time.
>
> Check that each placeholder is unambiguous, for example `[deadline_date]` rather than a vague blank, so filling it in later is fast and error-free.

Build a complete AI-powered communication system using Claude. You will learn how to judge tone and audience, match messages to the right channel, extract key points, draft clear communications, and organize everything into a reusable workflow.

Learn what makes a communication system reliable and how to prepare a structured workspace before drafting messages. You will define message categories, set style guidelines, and classify messages by type and audience.

Learn how to judge tone and audience fit, adapt messages, flag sensitive situations, and pull out the details a draft needs. You will adapt tone for different readers, flag high-stakes messages, extract key points, and handle conflicting expectations.

Turn everything you've built into finished messages. You will build reusable templates, generate final drafts, review them for tone and style compliance, and turn the process into a reusable Claude workflow.
