The Agentic Orchestration Layer
Isolated LLM features don't scale. We build a governed control plane that coordinates specialized agents across your real estate workflows — deterministic, observable, and safe by design.
Best Practices We Build In
The difference between a demo and a production agent layer is discipline. Every engagement ships with these by default.
Deterministic orchestration
Constrain the agent's decision space with explicit routing and state machines. Autonomy where it pays off, determinism everywhere else.
Typed tool contracts
Every tool an agent can call has a validated schema for inputs and outputs — no free-form side effects, no silent failures.
Guardrails & grounding
Validate inputs and outputs, enforce policy, and ground answers in retrieved data so agents act on facts, not hallucinations.
Human-in-the-loop
Irreversible or high-value actions pause for human approval. The agent proposes; a person confirms — with a full audit trail.
Observability & evals
Every step is traced, replayable, and scored against evals — so regressions are caught before they reach a tenant.
Cost & latency control
Model routing, prompt caching, and fallbacks keep responses fast and token spend predictable as volume grows.
