Scopes

Use these pages to understand the NeMo Relay runtime model before applying it in a use-case workflow.

Scopes

Ownership boundaries for agent runs, requests, workflows, tools, LLM calls, and nested runtime work.

Middleware

Guardrails and intercepts that sanitize, transform, block, or wrap tool and LLM execution.

Plugins

Configuration-driven bundles that install reusable middleware, subscribers, and adaptive behavior.

Events

Canonical lifecycle records for scopes, tool calls, LLM calls, marks, subscribers, and exporters.

Subscribers

Consumers for lifecycle events, including logs, traces, trajectories, analytics, and diagnostics.

Framework Integrations

Integration patterns for frameworks that own invocation boundaries, scheduling, retries, or provider payloads.
