Which instructions make Claude keep a consistent tone?
Describing the tone clearly
Words like friendly or professional mean different things to different people. Instead, describe the reader, the level of formality, and the kind of sentences you prefer. Short, direct sentences with no jargon work better than a single adjective.
- Name the audience and their expertise
- Give two or three adjectives with examples
- Say what to avoid, such as slang or exclamation marks
Showing a sample
Paste a short paragraph you like and ask Claude to match its rhythm and word choice. A sample often communicates tone faster than a long list of rules. Use a sample from your own writing where possible, so the match feels natural.
Keeping it steady
In a long conversation, the tone can drift as the topic changes. Restate the tone instructions when you start a new section, or start a fresh chat for a different kind of writing. Ask for a quick check of any draft that feels off.
If the tone still drifts after a few messages, paste the sample again rather than adding more adjectives. The example usually does the job better than more description. Keep the sample short, roughly one paragraph, so the match stays focused.
Common mistakes
- Asking for a friendly tone without saying who the reader is.
- Changing the instructions in every message so the tone keeps shifting.
- Expecting one instruction at the start of a long chat to hold without reminders.
