Your first chat and conversation controls

A useful chat starts with a clear task: the outcome, audience, source material and what must not be invented. You can improve a response by editing the request or continuing the conversation instead of starting over each time.

Start with a small task

By the end of this lesson, you will turn source notes into a useful update, spot unsupported claims, and revise a draft without losing the source. Open a new Chat conversation. No file, Project, or service connection is needed.

A manager wants to know what is ready, what is blocked, and what she must decide. The sample outputs were written for teaching. They are not filmed transcripts or promises of identical results.

A first prompt to copy

"Make this professional" leaves Claude guessing the audience, format, and missing details. Instead, paste:

Draft an update for the manager of an internal course.
Audience: a manager who is not involved in production details.
Goal: understand what is ready, what is blocked, and what needs a decision.
Format: three sections: Ready, Blocked, Decision needed.
Length: no more than 120 words.

Use only facts in the source. Do not add a date, owner, or reason for delay.
Mark missing information as not supplied. This is a draft, not for sending.

Source:
48 employees registered. The first two training units are ready.
Unit 3 is still being edited. Its completion date was not supplied.
The training room holds 30 people.
The manager must choose between two in-person groups and one online meeting.
The microphone has not been tested.

Audience controls how much to explain. The goal gives the update a purpose. Format makes it readable. The source limits the facts. "Do not add" is not a guarantee against mistakes, so check the output.

Compare the output with the source

An illustrative output:

Ready
48 employees registered, and the first two training units are ready.

Blocked
Unit 3 is still being edited; its completion date was not supplied.
The microphone has not been tested.

Decision needed
The room holds 30 people. Choose between two in-person groups
and one online meeting.

Check your actual answer, not just this example:

  • 48 registrations and 30 seats remain different numbers.
  • "Being edited" did not become "almost ready."
  • No unsupported date appeared.
  • An untested microphone did not become a broken microphone.
  • The two formats remain options, not an approved decision.

If Claude writes "We launch next week," ask:

Check the draft against the source text only.
List each claim that is absent from the source or does not follow from it.
Then return a corrected draft. Do not fill gaps with guesses.

This may help, but it is not automatic verification. Compare with the source yourself. Confident tone is not evidence.

Continue and improve the conversation

Now the manager wants a shorter version. Stay in the same chat so the draft and criteria are available:

Shorten the update to no more than 60 words.
Keep 48 registrations, 30 seats, Unit 3's status, and both format options.
Do not say the course is ready to launch.
End with: Which format would you like to choose?

Illustrative output:

48 employees registered and two units are ready. Unit 3 is being edited;
its completion date was not supplied. The microphone is untested.
The room holds 30 people, so a choice is needed between two in-person
groups and one online meeting. Which format would you like to choose?

Check numbers and approval status again. Shortening can remove an important fact. "Restore the fact that the microphone is untested" is more useful feedback than "Try harder."

Change audience or correct a fact

To change audience:

Make a version for employees rather than the manager.
Explain that the format is undecided. Do not present an option as approved
and do not add a date.

To update facts:

Update: there are now 42 registrations, not 48. Everything else is unchanged.
Return an updated draft and a short list of changes.

Check that 48 is absent from the new draft. If the interface lets you edit the original message, that can change the starting point, but the resulting answer still needs checking. Retrying an answer creates an alternative, not a truth check.

Give the chat a useful name, such as "Internal course - update draft." Before sharing, check what will leave your account. Copying one paragraph is different from sharing a conversation link that may contain internal context.

Practice at three levels

Easy: support every sentence

Run the first prompt and match each draft sentence to its supporting source. Success: no unsupported claims and no required facts missing.

Intermediate: change the audience

Ask for the employee version. Success: suitable wording, no invented date, and no approved format where none was chosen.

Challenging: update without side effects

Change registrations to 42 and request a change list. Success: the number changes, Unit 3's status stays the same, and no new approvals appear.

When an answer goes wrong

Polished but generic: define what the reader needs to decide and the output structure.

Missing information: leave it missing or ask the person who knows. Plausible completion is not appropriate for a factual update.

The chat drifts: restate criteria and supply the needed source again. Do not assume every old detail is always available.

Wording becomes a commitment: separate drafting, approval, and sending. A request to draft is not a sent message.

Take this into the next lesson

Start with audience, outcome, and source. Improve with precise follow-up requests. Check facts after every revision. The same method applies when the source arrives as a file.

The exercise prompts are original teaching examples based on explicit instructions, context, format, and examples. No claim is made that this exact wording is scientifically validated or always succeeds. Community tutorials can provide ideas, not authority on product availability.
