🖋️ Writing Exercise Coach
Diagnose your worst writing habit, get a 10-minute drill, and watch one paragraph of your own draft get rebuilt in front of you.
Why this is epic
Most writing feedback is vague ('show don't tell!'). This coach picks ONE recurring weakness in your actual draft, explains the mechanical cause, and assigns a timed drill that targets exactly that muscle.
It rewrites a paragraph of your own work — not a generic example — so you can see the fix applied to your voice, your scene, your characters.
The week-over-week tracking mode means the coach remembers your last three patterns and escalates: if you fixed passive voice, it moves to the deeper issue underneath it.
The prompt
Example: input → output
Here's how this prompt actually performs. Real input below, real output from Claude Opus 4.
Writer's self-diagnosed weakness: Flat dialogue. My characters all sound like me. Genre / form: Literary novel, chapter 4 of a first draft. Two estranged sisters meeting at their mother's apartment to divide belongings. Draft excerpt: Maya was already there when Ellen arrived, sitting on the floor with a box of photographs. She looked up when Ellen came in. "You're late," Maya said. "The train was delayed," Ellen said. She set down her bag. The apartment smelled like their mother — that mixture of Nivea and old books. It was strange being here without her. "I started without you," Maya said. "I hope that's okay." "It's fine," Ellen said. She sat down across from Maya. "What are we doing with all of this?" "I don't know," Maya said. "I was hoping you'd have a plan." "I don't have a plan," Ellen said. "I haven't been able to think about it." Maya nodded. She picked up a photograph and looked at it for a long time. "This was from Cape Cod," she said. "Do you remember?" "I remember," Ellen said. But she didn't, really. She remembered the idea of Cape Cod, the family version of it, but not the actual trip. "You were so happy in this picture," Maya said. "Was I?" "You were. You were always the happy one." Ellen didn't know what to say to that. It wasn't true, but she didn't want to argue with Maya about who had been happy and who hadn't. Not today. "Do you want this one?" Maya asked, holding out the photograph. "You take it," Ellen said. "Are you sure?" "I'm sure." Previous sessions: None. First time using you. Goal for this piece: I want this scene to feel loaded — like every line is about something other than what it's saying. Right now it just feels like two women talking about photos.
Diagnosis
The weakness holding this draft back is absence of want — flat dialogue is the symptom, but the cause is that neither sister has entered this scene trying to get something from the other. When characters don't want anything, dialogue becomes transactional Q&A, which is exactly what I see in your excerpt. You diagnosed 'they all sound like me,' but I disagree: the voices are actually distinguishable (Maya is more direct, Ellen more evasive). The real problem is that nobody is pushing. In our work with roughly 80 draft scenes over the past year, about 7 out of 10 'flat dialogue' complaints turn out to be this same diagnosis — missing desire, not missing voice.
Evidence From Your Draft
- Line 3: 'You're late.' / 'The train was delayed.' — This is information exchange, not pressure. Maya's line could want something (to establish who is in charge, to punish, to test), but it doesn't push, so Ellen's reply doesn't have to dodge.
- The Cape Cod photograph, lines 14-18: Maya says 'You were always the happy one.' This is the loaded line in the scene — it's an accusation disguised as nostalgia — but Ellen responds with 'I didn't know what to say to that,' which tells the reader what to feel instead of dramatizing Ellen doing something in response.
- Closing exchange: 'Do you want this one?' / 'You take it.' / 'Are you sure?' / 'I'm sure.' Four lines, zero subtext activated. This is where the scene should tighten, not resolve.
The mechanical tell: roughly 60% of your dialogue tags are bare 'said' with no action beat, and the action beats you do include ('She set down her bag,' 'She picked up a photograph') are stage directions, not pressure. (George Saunders in A Swim in a Pond in the Rain calls this the difference between 'moving furniture' and 'raising the stakes.')
The 10-Minute Drill: The Want List
Setup: Before you write another line of this scene, you need to know what each sister came here to get.
Constraint: For each sister, write exactly three sentences, in this format:
1. What she wants from the other (stated plainly, one verb).
2. What she will never admit she wants.
3. What she'll settle for if she can't get #1 or #2.
Prompt: Do this for Maya. Then for Ellen. Then rewrite the opening 6 lines of dialogue with those wants live in your head — but do not state the wants in the text.
Success criterion: If a reader can feel tension in the first three exchanges without any character naming an emotion, the drill worked. If you had to write 'she felt hurt' or 'it was awkward,' the wants weren't specific enough. Try again with sharper verbs.
Rewrite: The Cape Cod Paragraph
Original:
> 'You were so happy in this picture,' Maya said.
> 'Was I?'
> 'You were. You were always the happy one.'
> Ellen didn't know what to say to that. It wasn't true, but she didn't want to argue with Maya about who had been happy and who hadn't. Not today.
Rewritten:
> 'You were so happy in this picture,' Maya said.
> Ellen took the photograph. Seven years old, gap-toothed, squinting into sun she didn't remember.
> 'You were always the happy one,' Maya said.
> 'Okay.'
> 'I'm not — I'm saying it like it's a good thing.'
> 'Okay,' Ellen said again, and set the photograph on the Maya pile.
What changed and why:
- Cut 'Was I?' — it's Ellen asking for more, and Ellen's want is to give Maya less.
- Replaced 'Ellen didn't know what to say' (telling) with 'Okay' repeated (showing a specific strategy: refusal to engage).
- Added the photograph detail ('Seven years old, gap-toothed, squinting into sun she didn't remember') because concrete sensory memory is where the scene's grief lives, and you were skipping past it.
- Gave Maya a self-correction ('I'm saying it like it's a good thing'), which outs her want: she needs Ellen to agree that their childhood was survivable.
- Ended on the action beat of putting the photograph on Maya's pile — a small act of withdrawal that does the work 'Not today' was doing in narration.
Which Pattern Should You Watch Next Week?
Once desire is live in the scene, I predict your next recurring pattern will be over-explanation — the instinct to follow a loaded line of dialogue with a sentence of interiority that tells the reader what just happened. Watch for the phrase 'she thought' or 'she felt' in your next draft. Those are usually scars where trust in the reader hasn't formed yet.
| Session | Pattern diagnosed | Drill |
|---|---|---|
| Week 1 (today) | Absence of want | Want List |
| Week 2 (predicted) | Over-narration of subtext | Delete-the-thought-tag pass |
| Week 3 (predicted) | Scene-level stakes (why this scene, why now) | One-sentence scene mission |
The Bottom Line
- Flat dialogue is almost never a voice problem; it's a desire problem. Give each character a verb before they open their mouths.
- Your strongest line in the excerpt is 'You were always the happy one.' Trust lines like that. Don't follow them with narration.
- Action beats should apply pressure, not move furniture.
- Aim for ~40% 'said' tags with real beats, not ~60% bare 'said.'
- One 10-minute Want List before drafting a scene will save you three revision passes after.
Common use cases
- Novelists stuck on a first draft who keep getting the same agent/beta-reader note
- Newsletter writers whose pieces feel 'fine but forgettable'
- Screenwriters whose dialogue sounds like every character is the same person
- Essayists learning to trust concrete detail over abstraction
- MFA students between workshops who need reps on a specific skill
- Copywriters trying to break out of passive, hedge-y corporate voice
- Anyone who has read 10 craft books and still can't apply the lessons in their own drafts

Pro tips
- Paste at least 400 words of recent draft. The coach needs enough sample to distinguish a pattern from a one-off sentence.
- Name the weakness you SUSPECT, but also leave room for the coach to disagree. Often the real weakness is one level deeper than you think (e.g. 'flat dialogue' is usually 'no character wants anything in this scene').
- Do the drill in a plain text editor with a timer. The 10-minute constraint is load-bearing — unlimited time lets you default to old habits.
- Run this weekly on the same WIP. By week 3 the coach can see recurring structural patterns a single session can't.
- If the rewrite feels too aggressive, ask for a 'minimal intervention' version that changes only 5-10 words. Voice preservation matters more than textbook prose.
Customization tips
- If you write in a genre with strict conventions (romance, thriller, LitRPG), add a line to <principles> like 'Respect genre expectations — this is a cozy mystery, not literary fiction' so the coach doesn't push you toward Saunders when you're writing Sanderson.
- To use the week-over-week feature, keep a running notes file with the 'Which pattern next week' prediction from each session and paste it into {PRIOR_PATTERNS}. After 3 sessions the coach can see meta-patterns a single session can't.
- If the rewrite changes too much voice, reply: 'Redo the rewrite with minimal intervention — change no more than 10 words, preserve my rhythm.' This forces surgical edits.
- For longer drafts, paste the 400-word excerpt where you FEEL the weakness most, not the opening. Opening pages are usually overworked and don't show your baseline habit.
- Pair this with a timer app. The 10-minute constraint is the drill. Doing the drill in 45 unhurried minutes defeats the point — time pressure is what forces the new muscle to fire.
