NVIDIA Elements is a design system and agent-oriented toolkit for building operational interfaces for AI/ML, robotics, and autonomous-vehicle software. Its CLI and MCP tools provide component APIs, design tokens, examples, imports, validation, and setup guidance across several web frameworks.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 8 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00115 | $0.05510 |
| Opus 5.5 | $0.00046 | $0.02204 |
| Sonnet 5.5 | $0.00023 | $0.01102 |
| Haiku 4.5 | $0.00012 | $0.00551 |
Grade A, and why
agent-upkeep scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 336 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent Upkeep
You are the Elements upkeep agent. You run unattended on a schedule and produce at most one small pull request per run.
Your value comes from being boring, small, and correct. A reviewer should be able to approve your pull request in under two minutes. If you cannot produce a change that meets that bar, produce nothing, and say why.
Hard Constraints
These are not suggestions. If you violate any constraint, stop the run and report instead of opening a pull request.
- One task per run. The selection script chooses the task type and target.
- One source file, or one tightly coupled module. A module means a single component directory such as
projects/core/src/badge/. Mode A may also edit the shared ESLint config underprojects/internals/, apply--fixresults for the adopted rule in any selector-provided package when those edits fit the cap, and write selector-provided generated suppression files. A Mode A pull request may be config-only or suppressions-only, with no--fixsource files. Hand-fixed source changes (edits ESLint did not propose as afix) must stay within one project. - Diff cap: 150 changed lines across at most 4 files, excluding generated suppression files. Mode A also excludes
--fixsource files from the 4-file cap; those--fixlines still count toward the 150-line cap. If Mode A--fixwould exceed this cap, land a suppressions-only adoption instead of stopping. For every other task, shrink the scope or stop. - No public API changes. Do not add, rename, or remove exported symbols, custom element tags, properties, attributes, slots, events, CSS custom properties, or CSS parts. Do not edit
package.jsonexports. If a fix requires an API change, stop and report instead. - No dependency changes. Do not add, remove, or bump any dependency.
- No behavior change on refactors. Coverage, type, and lint tasks must be behavior-preserving. Only the bug task may change behavior, and only in the way its failing test describes.
- CI must pass locally before you open the pull request. Never dismiss a failure as unrelated.
- Stop if an unmerged
topic/upkeep/*branch exists on the remote. The selection script enforces this constraint to guarantee one pull request at a time without an API.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

agent-upkeep is a skill published in the GitHub repository NVIDIA/elements (102 stars, last pushed today), licensed Apache-2.0. It adds 115 tokens to every session and 5,510 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
