Sticker Cog - One Character, Twenty Expressions, Perfect Consistency
One character. Twenty expressions. Every sticker looks like the same person. That's the hard part — and that's what CellCog does better than anyone.
Generating one cute sticker is easy. Every AI tool can do that. But generating a complete pack of 20 stickers where the character has the same face, same style, same proportions — just different expressions and poses? That's consistency at scale, and it's where most AI tools completely fall apart. By sticker #10, your character looks like a different person.
CellCog maintains character identity across every single generation, delivers with transparent backgrounds, and packages everything for your target platform — WhatsApp, Telegram, Discord, Slack, or iMessage.
How to Use
For your first CellCog task in a session, read the cellcog skill for the full SDK reference — file handling, chat modes, timeouts, and more.
OpenClaw (fire-and-forget):
result = client.create_chat(
prompt="[your task prompt]",
notify_session_key="agent:main:main",
task_label="my-task",
chat_mode="agent",
)All agents except OpenClaw (blocks until done):
from cellcog import CellCogClient
client = CellCogClient(agent_provider="openclaw|cursor|claude-code|codex|...")
result = client.create_chat(
prompt="[your task prompt]",
task_label="my-task",
chat_mode="agent",
)
print(result["message"])Why Sticker Packs Are Hard
The challenge isn't making one sticker. It's making twenty that look like they belong together.
| The Problem | Why It's Hard | How CellCog Solves It |
|---|---|---|
| Character drift | Each AI generation drifts slightly — different face shape, different proportions | CellCog's reference image threading maintains identity across all generations |
| Style consistency | Line weight, color palette, and art style shift between generations | The agent establishes a visual style guide before generating and enforces it throughout |
| Expression range | Getting 20 genuinely different expressions without changing the character | CellCog plans the full expression set upfront, then generates each with the character locked |
| Transparent backgrounds | Many AI models struggle with clean transparency | Dedicated transparent background model produces clean cutouts |
| Platform formatting | Each messaging platform has different size, format, and packaging requirements | Automatic conversion and optimization for WhatsApp, Telegram, Discord, Slack, iMessage |

Tell CellCog which platform you're targeting and it handles the formatting automatically — dimensions, file format, file size optimization, and transparent background generation.
Chat Mode for Sticker Packs
| Scenario | Recommended Mode |
|---|---|
| Single sticker pack (10-20 stickers), emoji sets | "agent" |
| Multiple coordinated packs, brand sticker system, large sets (30+) | "agent team" |
Use "agent" for most sticker work. A single pack with 10-20 stickers executes well in agent mode.
Use "agent team" for brand-level sticker systems — when you need multiple packs that share a design language, or very large sets where consistency across 30+ stickers benefits from deeper creative planning.

Tips for Better Sticker Packs
- Describe the character in detail: "Orange cat" is vague. "Chubby orange tabby with green eyes, white chest patch, round face, always slightly smug expression" gives CellCog what it needs for consistency.
- Plan your expressions upfront: List all the expressions you want before generating. This helps CellCog plan the full set and avoid drift.
- Specify the style clearly: "Kawaii", "flat design", "chibi anime" — one clear style direction keeps the whole pack cohesive.
- Include reference images when possible: If you're making stickers from a pet photo, mascot design, or existing character, upload the reference. CellCog uses it to maintain likeness.
- Think about readability at small sizes: Stickers are viewed tiny. Bold outlines, simple shapes, and clear expressions read better than detailed illustrations.
- Platform first: Different platforms have wildly different requirements. "For WhatsApp" vs. "For Discord" changes dimensions, format, and file size targets. Always specify.
