Use this skill when an application owns tool or LLM/provider call sites and needs to wrap them with NeMo Relay scopes and managed execution APIs for lifecycle events, middleware, or guardrails.

What this skill does
Instrument Tool And LLM Calls Use this skill when an app already has tool functions or model/provider calls and needs to run them through NeMo Relay correctly. Keep the original callable behavior stable while adding Relay lifecycle capture. Default Guidance Put a scope around the natural agent, request, workflow, or graph boundary. Use managed execution APIs first: Rust: toolcallexecute(ToolCallExecuteParams::builder()...), llmcallexecute(LlmCallExecuteParams::builder()...) Python: tools.execute(...), llm.execute(...) Node.js: toolCallExecute(...), llmCallExecute(...) Go: tools.Execute(...), llm.Execute(...) or the top-level wrappers Use manual lifecycle APIs only when the host framework cannot be wrapped by the managed execute helpers. Embedded Runtime Semantics Managed tool and LLM execution runs conditional-execution guardrails first on the raw input. If rejected, the runtime emits a standalone mark event and does not run request intercepts or the callable. Request intercepts run after conditional guardrails and rewrite the real input that reaches execution intercepts and the callback. Sanitize-request guardrails affect emitted start-event payloads only. They do not rewrite the caller-visible request or arguments. Execution intercepts wrap the callback with the middleware next pattern and may short-circuit by returning their own result. Sanitize-response guardrails affect emitted end-event payloads only. The value returned to application code remains the raw callback or execution-intercept result. If execution fails after the start event has been emitted, the runtime still emits an end event without a semantic output payload. Tool calls are named operations with JSON-compatible arguments and results. Keep the original tool callable responsible for business logic; let NeMo Relay own lifecycle events, middleware, and metadata. LLM calls use an LLMRequest made of metadata plus content. …
