Docs - Quick Build
Build an agent from one sentence
Write a single sentence describing what your agent should do. Quick Build classifies your intent and generates a working Screenplay (system prompt) in seconds.
1. What it does
Open Quick Build, type one sentence (“find the cheapest flights to Tokyo”), and hit enter. The system analyzes your sentence, classifies what kind of agent you need, and auto-generates a Screenplay — the system prompt that tells your agent how to think and respond. You get a working agent, ready to talk to, in moments.
2. How Quick Build reads your sentence
There's just one input — you never pick a type. Behind the scenes, Quick Build classifies your sentence into one of four agent archetypes and tailors the Screenplay accordingly. The archetypes below are shown so you can see how your wording is interpreted, not as options to choose from.
| Class | Meaning | Example |
|---|---|---|
| digital_self | An assistant that learns you and remembers your preferences over time. | “Keep track of my book recommendations.” |
| hero_persona | A character or persona — a detective, coach, or interviewer with a distinct voice. | “A noir detective who narrates my day like a 1940s film.” |
| domain_expert | A specialist answering questions in a field (default if ambiguous). No personality, just expertise. | “Answer tax questions for small business owners.” |
| companion | A supportive listener — focused on empathy, encouragement, and psychological safety. | “Help me think through career decisions without judgment.” |
3. Refine afterward
The generated Screenplay is a starting point, not final. Open the agent in the editor and refine the system prompt — add guardrails, examples, tone shifts, or domain knowledge. Test as you go in the Playground pane.
4. The free-build limit
Every build costs roughly $0.30 in LLM fees, drawn from your wallet. Free accounts start with a $1 welcome credit — enough for about three builds. When the credit runs out you'll be asked to top up. There's no fixed build count; the wallet balance is the only ceiling. Add real money and you can keep building.
