How to Build Expression Sheets with Claude
Build expression sheets with Claude and ToolRouter. Generate a complete set of character emotions for animation, visual novels, and game dialogue.
Tool
Generate a complete set of facial expressions for any character for animation, visual novels, and dialogue systems. Claude is ideal for developing the emotional range — deciding which expressions the character needs, reviewing consistency, and flagging which emotions read ambiguously.

Steps
Once connected (see setup above), use the Character Sheet Maker tool:
- Upload the base character design and list the emotions needed — standard set or a custom list specific to the narrative.
- Run `expression_sheet` through `character-sheet-maker` to generate the full emotion set.
- Ask Claude to review the sheet — which expressions read clearly, which look too similar to adjacent emotions, which might be misread by players.
- Revise ambiguous expressions and export the finalised sheet for the animation or game production pipeline.
Example Prompt
Try this with Claude using the Character Sheet Maker tool
Use character-sheet-maker to create an expression sheet for this character — I need 8 emotions: neutral, happy, sad, angry, surprised, nervous, disgusted, and determined. Review the set and tell me which expressions read most ambiguously and which need a second pass.
Tips
- Name each expression state explicitly rather than saying 'all standard emotions' — the specific list determines the output.
- Ask Claude to compare adjacent emotions (nervous vs. scared, happy vs. excited) to confirm they are visually distinct.
- Export the sheet as a grid image for easy reference alongside individual expression files for production use.
