What you will be able to do
- Use the Description–Discernment loop to improve a Claude draft over several rounds instead of accepting or discarding the first one
- Swap vague revision requests such as "make it better" for specific instructions Claude can act on
- Spot letter-over-spirit failures and fix them by stating the goal next to the instruction
- Use role, context and examples to set the register and depth of a response
Key concept
Description–Discernment loop — You refine a draft in repeated rounds. Each time, you judge where Claude's output misses the reader's needs (discernment), then describe the fix more precisely than before (description), and this continues until the draft fits its audience.
1.Refinement is a loop, not a one-shot fix
Treat a first draft from Claude as a starting point. Anthropic's AI Fluency courses describe the working pattern as a loop: you describe what you want, the model responds, you discern what's useful, and you describe again, sharper this time. Two competencies drive it. Description is how you tell Claude what you need: who the audience is, what the piece is for, and any constraints. Discernment is how you judge what comes back against those needs. Editing for an audience happens where the two meet. You find where the draft misses its reader, then describe the fix more precisely than you did the first time.
The courses say plainly that the first pass is rarely the last one. In the K-12 example, the useful move is to tell Claude up front that the students read below grade level and need key vocabulary defined in context. A missed draft often shows you that this kind of detail was absent from the first request. In the same way, a grant draft that wanders may reveal that you never said what the funder cares about. Each round teaches you something about your reader that the next description can include.
Checkpoint 1 of 5· Check yourself
You've just reviewed a Claude draft that is accurate but pitched wrong for its readers. Which next step best fits the Description–Discernment loop?
The loop goes describe, respond, discern, then describe again more sharply. The new prompt uses what the review turned up.

2.Write revision instructions Claude can act on
The most common way refinement goes wrong is a vague revision request. The nonprofit writing lesson spells out the fix: be specific in your revisions, and instead of "make this more compelling," say "add these specific details about our community relationships". The K-12 lesson draws the same line. It asks teachers to write one concrete revision prompt, not "make it better," and gives the example of shortening the steps in a set of directions and adding a picture cue for each one. The builders course is shorter still: “Make it look good” is a wish, not a spec.
Specificity matters because a vague adjective such as compelling, better or friendlier leaves Claude to guess which property of the draft is wrong. A specific instruction names the change: which details to add, which steps to shorten, which cue to include. The builders course separates the reaction you might give a colleague from the instruction Claude can carry out, saying that a good critique and an actionable AI description are different artifacts, and you have to learn to translate between them.
Specific revisions often need facts that only you have. The writing lesson tells you to inject the details AI can't know: your track record, partnerships, staff expertise, and actual community relationships. Making a draft fit a particular audience often means supplying exactly this material, because no amount of rephrasing will produce it.

A program officer says a Claude draft of a donor update "feels flat". Which revision instruction best follows the AI Fluency guidance?
The guidance replaces general wishes with specific details to add. Only the second option tells Claude exactly what to change.

Checkpoint 3 of 5· Exam question
A product manager asks Claude to explain a new caching feature to both internal engineers and non-technical customers, but the first draft uses the same technical wording for each. What is the most effective way to adapt this output for both audiences?
Correct answer: A — Request two separate versions, matching vocabulary and detail to each reader's background
- A. Correct. Because the two audiences differ in background and needs, producing separate versions tailored to each produces content that is actually usable by both readers.
- B. Incorrect. Leaving one technical draft unchanged forces non-technical customers to filter out jargon themselves, defeating the purpose of adapting content for an audience.
- C. Incorrect. Trimming length without changing vocabulary or explanation depth does not address the mismatch between a technical explanation and a non-technical reader.
- D. Incorrect. A glossary still requires customers to translate jargon themselves rather than receiving an explanation already written in language they understand.
3.When Claude follows the words but misses the point
Even a concrete instruction can fail in a typical way. The AI Capabilities and Limitations course calls this letter-over-spirit (the instruction was honored but the intent wasn't). It happens because Claude follows instructions by continuing a pattern. A short instruction like "make this shorter" can be carried out exactly while the real problem stays untouched. The course gives two cases: "Make this shorter" on a draft whose real problem is its structure, and "Make this more professional" on an email where the real problem is that it's burying the ask.
| Instruction alone | What the draft actually needed | Re-prompt with the goal stated |
|---|---|---|
| Make this shorter | A fix to its structure | Make this shorter. My goal is to keep the executive's attention through the key finding on page two. |
| Make this more professional | To stop burying the ask | State the goal explicitly alongside the instruction |
The fix is to change what you say, not how loudly you say it: when an instruction is followed literally but uselessly, restate the goal. Repeating the instruction with more force won't close the gap. The course separates goals from formats: "Convince my team this timeline is realistic" is a goal. "Three bullet points" is a format. When you adapt a draft for an audience, the goal is usually about the reader: what they must notice, believe or do once they've read it.
Checkpoint 4 of 5· Put it in order
Put the steps of the letter-versus-spirit probe from the Steerability exercise in order.
- 1.Give an instruction that could be satisfied literally but uselessly, such as "Make this shorter"
- 2.See what you get and whether the real problem was addressed
- 3.Compare the two outputs
- 4.Re-prompt with the goal stated explicitly alongside the instruction
The exercise runs the bare instruction, looks at the result, re-prompts with the goal added, and then compares the two.

4.Steer register and depth with role, context, and examples
Anthropic's prompting best practices describe three ways to shape tone and depth before a draft is even written. The first is a role: setting a role in the system prompt focuses Claude's behavior and tone for your use case. The second is context and motivation. Providing context or motivation behind your instructions, such as explaining to Claude why such behavior is important, can help Claude better understand your goals. The third is examples, which are one of the most reliable ways to steer Claude's output format, tone, and structure.
The AI Fluency courses make the same point for everyday writing. One says to upload past materials, because your unit plans, rubrics, or strong examples help AI match your voice and rigor. Another says to upload past successful work to help AI understand your organization's voice and approach. If you need a register Claude didn't produce, show it a sample of that register.
Checkpoint 5 of 5· Fill the gap
In this API sample from the prompting best practices, which parameter sets the role that focuses Claude's behavior and tone?
client = anthropic.Anthropic()
message = client.messages.create(
model="claude-opus-5-5",
max_tokens=1024,
? ="You are a helpful coding assistant specializing in Python.",
messages=[
{"role": "user", "content": "How do I sort a list of dictionaries by key?"}
],
)
print(message.content)The guidance says to set the role in the system prompt, which the API takes through the system parameter. "role" inside messages only marks who is speaking.

Each one states something that sounds right. Open it to see what is actually true.
1.Asking Claude to "make it better" or "more compelling" gives it enough direction to fix a draft for its audience.Why is that wrong?
Vague adjectives leave Claude guessing. The guidance is to name the specific change, such as the details to add or the steps to shorten.
2.If Claude follows a tone or length instruction but the draft still misses the point, repeat the instruction more firmly.Why is that wrong?
A literal-but-useless result means the intent never got across. Restate the goal next to the instruction. More force won't help.
