What it does

What you get back

Creates nine individual square doodle stickers from a single photo. Each sticker shows the same recognizable character in a different expression (happy, laughing, love, sad, angry, shocked, thinking, sleepy, thumbs up) with matching die-cut borders, designed for use as a custom messaging sticker set.

When the agent picks it

Use when the user wants an expression pack, reaction stickers, emotion set, or multiple expressions of the same person from a photo.

Expression Pack

Turn one uploaded photo into 9 separate square doodle stickers — the same character in nine distinct expressions, each its own image file.

When this is the right skill

Pick this skill when the user wants:

An expression or reaction sticker set of themselves
Multiple emotions / moods of the same character
A messaging sticker pack (WhatsApp, Telegram, iMessage, Discord)
“Give me different reactions” or “make me an emoji set”

Do NOT use this for a single sticker sheet image (use sticker-pack instead) or for a collage grid (use collage or mood-captions).

What to draw

Nine separate 1:1 images, each a head-and-shoulders naive marker-and-ink doodle of the same person showing one expression:

Happy — big smile, sparkles
Laughing — head back, mouth wide
Love — hands forming heart, floating hearts
Sad — downturned mouth, teardrop
Angry — crossed arms, vein-pop mark
Shocked — wide eyes, O mouth, exclamation lines
Thinking — chin-in-hand, thought bubble
Sleepy — droopy eyes, Zzz marks
Thumbs Up — confident grin, raised thumb

Character consistency is paramount: hairstyle, hair colour, face shape, skin tone, accessories, and outfit are identical across all nine. Only expression, head tilt, hand gesture, and emotive marks change.

How to run it

Confirm a photo is attached. If none is available, ask the user to attach one.
Call generateDoodle with skill: "expressions" and the uploaded photo as imageUrl.
Pass refImageUrl when the message includes a separate style reference.
The tool returns NINE separate images (one per expression). Cost: 9 credits (one generation per image).
Report the result briefly; the app renders all nine images in a grid.

Following up

Offer to regenerate a single expression the user dislikes, suggest a different theme, or recommend the sticker-pack skill for a composite sheet layout instead.
