test-node-binding

A set of instructions for building and testing the NeMo Relay connection used by Node.js programs. Node.js is a tool for running JavaScript outside a web browser.

In plain words
What is it for?
Use it when working on the project's Node.js code, generated Node.js interface, Node.js examples, or related documentation.
Why use it?
It gives developers a defined way to format, build, and test Node.js changes, including extra checks when Rust code is also changed.

Token cost

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.

Security

Grade A, and why

test-node-binding 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 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.

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.

What it actually says

Build And Test Node Binding

Companion Guidance

Use karpathy-guidelines alongside this skill for implementation or review work. Keep changes scoped, surface assumptions, and define focused validation before editing.

Use this skill when the change is primarily in crates/node, the generated Node surface, or Node-facing examples/docs.

Default Path

  1. Format changed Node files with npm run format --workspace=nemo-relay-node.
  2. Install dependencies and build with just build-node when you need to validate packaging/build output.
  3. Run just test-node for the normal dev/test loop.
  4. If any Rust files changed as part of the Node work, also run cargo fmt --all, just test-rust, and cargo clippy --workspace --all-targets -- -D warnings.
  5. Use just ci=true test-node when you want the CI-style coverage and JUnit path.

Common Commands

# Explicit release build
just build-node

# Format Node files
npm run format --workspace=nemo-relay-node

# Standard test loop
just test-node

# Required when the Node change also touched Rust code
cargo fmt --all
just test-rust
cargo clippy --workspace --all-targets -- -D warnings

# CI-style coverage and JUnit test loop
just ci=true test-node

Useful Extras

# Public API docstring checks when surface docs changed
npm run check:docstrings --workspace=nemo-relay-node

When To Escalate

  • If the change touched crates/core, crates/adaptive, or the generated Rust binding layer under crates/node/src, also use validate-change.
  • If the change is just documentation around Node usage, keep validation targeted.

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.

test-node-binding is a skill published in the GitHub repository NVIDIA/NeMo-Relay (132 stars, last pushed 2d ago), licensed Apache-2.0. It adds 26 tokens to every session and 493 once invoked, about $0.0001 per session on Opus 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.
