🎭 Character Design Deep Sheet
A 360° psychological profile with contradictions, verbal tics, and the secret your character keeps from themselves.
Why this is epic
Most character sheets are dead data — hair color, favorite food, Zodiac sign. This one surfaces the stuff that actually makes characters feel alive: the contradiction that drives them, the verbal tic readers will recognize by line three, and the truth they'd lie to a therapist about.
It forces the character through scenarios you didn't think to write: how they apologize, how they flirt badly, what they do when alone in a hotel room. The gaps between answers are where real characters live.
It ends with a 'break test' — how this character fails the plot you have planned — so you fix the mismatch before you write 40,000 words of the wrong book.
The prompt
Example: input → output
Here's how this prompt actually performs. Real input below, real output from Claude Opus 4.
Character seed: Miriam Katz, 54, widowed rabbi in Cleveland, 1987. She leads a mid-sized Reform congregation she inherited from her husband after his sudden death from a heart attack 18 months ago. The congregation thinks she's healing beautifully. She is not. Story context: Literary fiction, close third POV, one year in her life. The inciting incident is that a 16-year-old congregant comes to her for bat mitzvah prep and, in conversation, says something that cracks Miriam open — she realizes she no longer believes in God and hasn't for months, maybe longer. The book is about what she does with that. Core wound or formative event: Her husband David died mid-sentence at their kitchen table. She was pouring coffee. She did not catch him in time.
Miriam Katz — Deep Sheet
1. The One-Line Contradiction
A rabbi who has stopped believing in God but has never been better at her job.
2. Surface vs. Interior
To the congregation, Miriam is a miracle. Her sermons since David's death have gotten sharper, warmer, more textured — people say she's speaking from a deeper place now. She laughs at the right moments at kiddush. She has lost maybe ten pounds but wears it well. Bernice Applebaum told the sisterhood that Miriam is 'an inspiration of faith under fire.'
Underneath, Miriam is running a controlled demolition. She prays in public and the words come out like a second language she used to be fluent in. She has not opened her own siddur at home in four months. She has become an extraordinary rabbi in exactly the way a person becomes an extraordinary liar: by listening harder, because she can no longer afford to miss anything.
3. The Secret She Keeps From Herself
She is not grieving David. She is furious with him. He died in the middle of telling her something unimportant about the Brodsky wedding, and the last year of their marriage had been quietly, unspeakably dull. She misses him the way you miss a radio you didn't realize was on. If you asked her directly whether her marriage was happy, she would say 'of course' and mean it — and this is the lie underneath every other lie. The loss of God is downstream of this. She cannot be angry at David without admitting the marriage was smaller than the eulogy she gave, and so the anger has rerouted itself upward, at the Name she used to speak so easily.
4. Verbal Tics & Speech Patterns
- Overuses the phrase 'of course' — especially when something is not, of course, the case. It's her tell.
- Under stress, defaults to the rabbinic structure of 'On the one hand... on the other hand...' even in personal conversation. It buys her three seconds.
- Never says 'I feel.' Says 'one feels,' 'people feel,' 'there's a feeling that.' Her grief is always in the third person.
- When lying, she becomes more specific, not less. Adds a detail nobody asked for. 'I slept fine — I even read a chapter of the Heschel before bed.' She did not.
5. Physical Tells
- When lying: touches the back of her left earring, a pair David gave her for their 20th.
- When attracted to someone (this will happen and she is not ready): she goes quiet and starts listening with her whole face. It is devastating and she does not know she does it.
- Before losing her temper: her voice gets softer, not louder. Congregants have learned this. Her daughter has not.
- Alone: she eats standing up at the counter, always. Has not sat at the kitchen table since.
6. Contradictions Inventory
- Believes Judaism is a practice, not a belief / Behaves as if her own disbelief disqualifies her entirely.
- Believes in the dignity of honest conversation / Has not had one with herself in eighteen months.
- Believes grief is sacred / Privately finds other people's grief exhausting and a little theatrical.
- Believes she is a feminist / Was quietly relieved, in the first week, that the congregation let her keep David's pulpit without a fight, and has not examined why.
- Believes she is patient with teenagers / Is, in fact, only patient with teenagers; adults have started to bore her in a way that frightens her.
7. How She Handles the Eight Situations
- Apologized to: Accepts too quickly, to end the discomfort. The apologizer leaves feeling worse.
- Complimented: Redirects it to someone else in the room within one sentence. Has done this her whole life.
- Ignored: Relieved. Then, twenty minutes later, hurt.
- Caught in a lie: Doubles down with a better lie. She is good at this and it scares her.
- Falling in love: Will not recognize it. Will call it 'a meaningful friendship' until it is catastrophically too late.
- Grief: Performs it correctly in public; at home, cleans.
- Boredom: Reads the same page of the same novel six times and calls it studying.
- Alone in a hotel room at 2am: Orders room service she doesn't eat, watches local news with the sound off, does not pray.
8. The Moral Line She Won't Cross
She will not lie to a child. Adults, yes — herself, constantly — but not a child, and specifically not a child asking a religious question. This is why the 16-year-old is going to destroy her. Miriam has built a year of scaffolding out of adult-appropriate evasions, and a teenager asking 'do you actually believe any of this?' is the one question her entire ethical architecture has no prepared answer for. She will tell the truth because she cannot do otherwise, and she will not have decided in advance what the truth is.
9. What She Wants vs. What She Needs
- Wants: To get through the year without anyone noticing.
- Needs: To be noticed, specifically, by someone who will not let her off the hook.
10. Break Test — How This Character Fails Your Plot
Three mismatches to watch:
1. The crack scene is too early for who she is. As written, Miriam is so defended that a teenager's offhand comment wouldn't crack her — it would bounce. She'd go home, pour a scotch, and file it. You need to either (a) make the teenager someone with specific leverage over Miriam (a kid she's known since birth, a kid who reminds her of the daughter she's estranged from, a kid asking the exact question David once asked her) or (b) accept that the 'crack' is slower, and the inciting incident is actually the third or fourth conversation, not the first.
2. She will not have a crisis of faith on-page in the way literary fiction expects. Miriam doesn't weep in synagogues. She cleans. A novel that needs big emotional beats from her will fight her the whole way. Lean into it — her refusal to break down is the book. The reader should be the one breaking down on her behalf.
3. You are going to want her to reconcile with God by the end. She won't. Given who she actually is, the honest ending is not a return to faith but a return to practice without faith — which is a much harder, much more Jewish book, and the one you should actually write. If you need her to believe again by chapter 30, you've written a different character. Change the ending, not her.

Best AI model for this
Claude Opus 4 or GPT-5 Thinking. This prompt rewards models that can hold internal contradiction without flattening it into 'quirky but lovable.' Avoid smaller models — they default to Hollywood archetypes.
Pro tips
- Feed it constraints, not just a name. 'A 54-year-old widowed rabbi in 1987 Cleveland who is secretly losing her faith' produces gold. 'A strong female protagonist' produces sludge.
- Run the same character twice with different 'core wound' inputs and compare — the one that makes you wince is usually right.
- After generating, delete everything except the contradiction, the secret, and three verbal tics. That's your actual character bible. The rest is scaffolding.
- If the 'break test' identifies a plot mismatch, change the plot, not the character. Characters who survive rewrites are the ones worth keeping.
- For ensemble casts, run this separately for each character, then ask Claude to identify which two will have the most interesting friction.
- Use the verbal tics in your first draft religiously, then cut 60% in revision. Readers feel the pattern subliminally even when most of it is gone.
Customization tips
- The character seed is where 80% of the output quality is decided. Specificity is not optional — give it era, location, profession, relational status, and one concrete detail nobody would guess.
- If the 'break test' at the end makes you defensive, that's the signal it's right. Sit with it for 24 hours before dismissing it.
- Run this once with a core wound you provide, and once with the wound left blank. Compare. The one the AI invents is sometimes sharper than yours because it isn't trying to honor your outline.
- Feed the output back into Claude with the prompt 'Now write a 400-word scene where this character is alone in a hotel room at 2am.' The verbal tics and physical tells will transfer automatically. This is the actual test of whether the sheet works.
- For series work, re-run this sheet every 3-5 books. Characters drift. Yours should too.
Variants
Antagonist Mode
Reframes outputs around the villain's internal logic — why they believe they're the hero — and generates the one scene that would make a reader almost agree with them.
Ensemble Friction Map
Takes 3-6 characters at once and maps the specific fault lines between them: who misreads whom, who secretly envies whom, and which pair should never be left in a room alone.
Historical Accuracy Pass
For period pieces — cross-checks language, worldview, and class markers against the specified era so your 1890s character doesn't 'process their trauma.'
