5 sections, as written by the authorNeMo 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
_typevalues withnat info componentsbefore writing workflow, evaluation, optimizer, logging, or tracing YAML. - Do not invent
_typenames or configuration keys from memory. - Use
natonly 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.

Discovery Commands
uv run nat info components -t function
uv run nat info components -t llm_provider
uv run nat info components -t evaluator
uv run nat info components -t logging
uv run nat info components -t tracing
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.

Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.
Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.

Replace with description of the skill and when Claude should use it.
Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies
This skill should be used when the user wants to "create a skill", "add a skill to plugin", "write a new skill", "improve skill description", "organize skill content", or needs guidance on skill structure, progressive disclosure, or skill development best practices for Claude Code plugins.
Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.
Use when creating new skills, editing existing skills, or verifying skills work before deployment
How to use it
Take nvidia/nat-user-rules from the repository into ~/.claude/skills for personal
use, or into .claude/skills inside a project.
The agent identifies a skill by the name field in its header. Two skills with the
same name cannot sit side by side — one of them will be ignored.
