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.

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 | $0.03066 | $0.03066 |
| Opus 5 | $0.01533 | $0.01533 |
| Sonnet 5 | $0.00613 | $0.00613 |
| Haiku 4.5 | $0.00307 | $0.00307 |
Grade C, and why
elements AGENTS.md scanned grade C with 2 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 2d 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.

AGENTS.md
This file provides guidance to AI Agents when working with code in this repository.
Instruction Precedence for Agents
When instructions conflict, follow this order (highest to lowest):
- Runtime or platform constraints from the agent host
- Repository agent rules in
AGENTS.md - Task-specific skill instructions in
.claude/skills/*/SKILL.md - Documents explicitly required by a selected skill (for example, docs in
projects/site/src/docs/internal/guidelines/) - General project documentation such as
README.md
Notes:
README.mdis primarily for orientation and setup; it does not override agent policy.- If a skill says you MUST review a referenced guideline, treat that guideline as required for that task.
- If two same-level sources conflict, prefer the more specific and recently maintained source, and note the assumption in your response.
Repository Overview
Elements is a design language for AI/ML factories built as a monorepo containing framework agnostic Web Components (Lit), themes, styles, testing utilities, and starter templates. The repository uses pnpm workspaces with Wireit for build orchestration and Semantic Release for automated versioning/publishing.
Environment Requirements
- mise: Toolchain manager for local development and CI (
mise.toml) - Node.js: 26.7.0 (managed via mise and validated against
.nvmrcandpackage.jsonengines) - pnpm: 11.23.0 (managed via mise and validated against
package.json) - Go: 1.26.4 (managed via mise for the Go starter)
- Git LFS: Required for visual test screenshots and videos (
.gitattributesdefines tracked files) - Playwright: Browser-based testing uses Chromium (installed via prepare script)
- Vale: Prose linter for documentation and JSDoc (managed via mise)
Common Commands
Repository Setup
# Install required tools and run CI
curl https://mise.run | sh
# If mise is not on PATH yet, use ~/.local/bin/mise for the setup commands.
mise trust
mise run setup
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.

elements AGENTS.md is an instructions file published in the GitHub repository NVIDIA/elements (83 stars, last pushed 2d ago), licensed Apache-2.0. It adds 3,066 tokens to every session, about $0.0153 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
