Story Genres
| Genre | Characteristics | CellCog Strengths |
|---|---|---|
| Fantasy | Magic, world building, epic scope | Deep world creation, consistent magic systems |
| Sci-Fi | Technology, speculation, ideas | Hard science integration, future extrapolation |
| Mystery/Thriller | Suspense, clues, twists | Plot structure, misdirection, pacing |
| Romance | Emotional depth, relationships | Character chemistry, emotional beats |
| Horror | Fear, atmosphere, dread | Tension building, psychological depth |

Chat Mode for Stories
| Scenario | Recommended Mode |
|---|---|
| Short stories, scenes, character work, outlines | "agent" |
| Complex narratives, novel development, deep world building | "agent team" |
Use "agent" for most creative writing. Short stories, individual scenes, and character development execute well in agent mode.
Use "agent team" for narrative complexity - novel-length outlines, intricate plot development, or multi-layered world building that benefits from deep thinking.

Tips for Better Stories
-
Genre expectations: Readers have expectations. Honor them or subvert them intentionally, but know what they are.
-
Character drives plot: Give CellCog clear character motivations. Plot emerges from characters wanting things.
-
Specific details: "A coffee shop" is generic. "A coffee shop with mismatched furniture and a cat named Hemingway" is memorable.
-
Emotional truth: Even in fantasy, the emotions should feel real. Specify the emotional journey you want.
-
Show, don't tell: Ask for scenes, not summaries. "Write the moment she realizes..." not "Describe that she was sad."
-
Iterate: First drafts are starting points. Use CellCog to revise, expand, and refine.
