Sierra
by Sierra
Builds customer-facing conversational agents with a declarative Agent SDK, guardrails, and an Agent OS runtime spanning voice, chat, email, and SMS.
Skills
Declarative Agent Definition
Describes agent behavior, tools, and escalation paths in a declarative language rather than hand-written prompts.
Guardrails
Constrains what an agent may say and do so customer-facing conversations stay inside policy boundaries.
Omnichannel Delivery
Runs the same agent across voice, chat, email, and SMS with channel-appropriate behavior on each surface.
