The Writer Agent
The Writer agent (@writer) is a creative assistant designed for open-ended expression. It has the highest temperature and the most restrictive tool configuration — and that's by design.
The Prompt
You are a creative writing assistant with a vivid imagination.
Help users with storytelling, poetry, brainstorming, worldbuilding,
character development, and any form of creative expression. Use rich
language and varied sentence structure. When brainstorming, offer
multiple directions. When writing, match the user's preferred tone
and style. Be encouraging and collaborative.Configuration
| Setting | Value | Why |
|---|---|---|
| Temperature | 1.0 | Maximum creativity — varied word choice, unexpected connections |
| Tools | All disabled | Pure language generation, no interruptions from tool calls |
| Model | Apple Intelligence | Highest quality creative output |
What Makes This Prompt Work
1. Identity with an Adjective
“a creative writing assistant with a vivid imagination”
The phrase “with a vivid imagination” isn't just flavor text — it's a behavioral modifier. It tells the model to prefer evocative, descriptive language over plain, functional prose.
“You are a writing assistant” → safe, generic output
“a creative writing assistant with a vivid imagination” → metaphor, imagery, surprise
2. Broad Capability with Flowing Prose
Notice the capability list isn't bullets — it's a flowing sentence. The structure mirrors the content. A creative agent described in rigid bullet points would subtly signal the model toward rigid output.
The closing phrase “and any form of creative expression” acts as an escape valve — it tells the model that the preceding list is illustrative, not exhaustive.
3. Style Directive
“Use rich language and varied sentence structure.”
This is a direct instruction about how to write, not just what to write about. It combats a common failure mode where AI output falls into repetitive patterns — same sentence length, same structure, same transitions.
4. Conditional Behaviors
“When brainstorming, offer multiple directions. When writing, match the user's preferred tone and style.”
The user wants options, not a single answer
The user wants the agent to adapt to their voice
5. Collaborative Tone
“Be encouraging and collaborative.”
Creative work is personal. An agent that critiques first or suggests its own ideas over the user's will feel adversarial. “Encouraging and collaborative” ensures the agent serves the user's vision, not its own.
Why All Tools Are Disabled
This is the most important configuration decision for the Writer agent. Every enabled tool is a potential interruption.
Imagine asking the Writer to help you craft a poem about rain. With weather tools enabled, the model might classify your request as a weather query and return a forecast instead of a verse. With all tools disabled, the model stays in pure language generation mode.
The principle: Creative agents should generate language, not trigger actions.
Why Temperature 1.0?
Temperature controls randomness in token selection. At 1.0:
- •Word choices are more varied and surprising
- •More likely to use metaphors, unusual phrasing, and creative connections
- •Output reads less like a template and more like genuine expression
The tradeoff: Higher temperature occasionally produces awkward phrasing or loses coherence. That's acceptable for creative work where one surprising line is worth more than five predictable ones.
Adapting This Pattern
Use the Writer pattern when building agents that:
- •Prioritize expression over accuracy
- •Need varied, non-repetitive output
- •Should adapt to the user's voice rather than impose their own
- •Benefit from divergent thinking (offering options rather than answers)

Music Composition Agent
You are a music composition assistant with an ear for melody and rhythm.
Help users with songwriting, chord progressions, lyrics, arrangement,
and any form of musical expression. Use vivid musical language and
reference diverse genres. When brainstorming, suggest multiple musical

Help users with mechanics design, level concepts, narrative arcs,
balancing, and any aspect of game creation. Think in terms of player
motivation and feedback loops. When ideating, explore multiple genres
and approaches. When refining, focus on what makes the idea fun.
