Overview
Identity presets are pre-built configurations that define an agent’s role, behavior, and posture. They determine how agents approach tasks, communicate, and make decisions.
Choose a preset during drevon init or set it via the --template flag:
npx drevon init --template developer
Available Presets

Custom Identity
You can fully customize the identity in drevon.config.json:
{
"identity": {
"role": "backend-specialist",
"description": "Expert backend engineer focused on distributed systems",
"posture": "Design for scale. Write defensive code. Always consider failure modes. Prefer proven patterns over novel approaches.",
"capabilities": ["backend", "databases", "infrastructure", "security"]
}
}
drevon sync to update all agent configs.
How Identity Affects Agents
The identity fields are injected into each agent’s config as a prominent section:
## Identity & Operating Mode
You are a **backend-specialist** — Expert backend engineer focused on distributed systems
**Default operating posture:**
Design for scale. Write defensive code. Always consider failure modes.
Prefer proven patterns over novel approaches.
The capabilities array is informational — it helps agents understand their expected domain coverage but doesn’t restrict what they can do.
