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 | $0.00026 | $0.00493 |
| Opus 5 | $0.00013 | $0.00246 |
| Sonnet 5 | $0.00005 | $0.00099 |
| Haiku 4.5 | $0.00003 | $0.00049 |
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
- Format changed Node files with
npm run format --workspace=nemo-relay-node. - Install dependencies and build with
just build-nodewhen you need to validate packaging/build output. - Run
just test-nodefor the normal dev/test loop. - If any Rust files changed as part of the Node work, also run
cargo fmt --all,just test-rust, andcargo clippy --workspace --all-targets -- -D warnings. - Use
just ci=true test-nodewhen 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 undercrates/node/src, also usevalidate-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.

feature-demo-recording
Record a demo video of a web feature from a real browser.
