Nat User Rules

NeMo Agent Toolkit User Rules

Use this skill first when working in the NeMo Agent Toolkit repository. It routes tasks to focused skills and states rules that apply across all toolkit work.

Mandatory Rules

• Discover registered component _type values with nat info components before writing workflow, evaluation, optimizer, logging, or tracing YAML.
• Do not invent _type names or configuration keys from memory.
• Use nat only for technical identifiers such as the CLI, package name, Python namespace, paths, and environment variables.
• In prose, use "NVIDIA NeMo Agent Toolkit" on first use, then "NeMo Agent Toolkit" or "the toolkit".
• Prefer existing examples and docs before creating new patterns.
• Keep generated examples runnable from the repository root unless the surrounding example uses another convention.

Skill Evolution

If a user corrects the skill routing, a command fails and the recovery is reusable, or a reference is stale, finish the user task first. Then read skills/skill-evolution/SKILL.md and update the relevant focused skill if the lesson should generalize.
