NVIDIA/NeMo-Relay is a runtime and library that gives coding agents and applications shared control over agent execution scopes, policies, plugins, lifecycle events, and observability data. It is for developers who need to inspect or instrument runs from agents such as Codex or Claude Code, or integrate frameworks and export traces and trajectories. The catalogue entries provide Relay plugins, hooks, instructions, skills, and an MCP server for those workflows.
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.

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 | $0.00053 | $0.01127 |
| Opus 5.5 | $0.00021 | $0.00451 |
| Sonnet 5.5 | $0.00011 | $0.00225 |
| Haiku 4.5 | $0.00005 | $0.00113 |
Grade A, and why
nemo-relay-install 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 15d 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 — 111 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Install NeMo Relay
Resolve what the user needs, install the appropriate current stable package or executable, verify availability, and stop. Installation does not include a first application, plugin configuration, scopes, or a model-consuming trial.
Disambiguate Before Installing
Establish the desired outcome and the boundary that owns execution before selecting a Relay type. Inspect available project context, but do not assume that a Python manifest means the user wants a Python binding rather than Relay for their coding agent.
When the target is unclear, ask one concise question:
Are you adding Relay to an existing agent runtime or framework, integrating it into your own application, or using its CLI or local gateway?
Resolve the named runtime, framework, language, or plugin only as far as needed to select its installation instructions. Preserve an explicit choice or an earlier handoff; do not repeat questions already answered. A generic "install Relay" or "try Relay" request alone does not authorize choosing the CLI.
| Established target | Reference |
|---|---|
| CLI, coding-agent wrapper, or persistent host integration | CLI Installation |
| Native agent integration, framework integration, or plugin bundle | Maintained Integrations |
| Application-owned language binding | Language Packages |
| Explicit contributor or source-build request | Current repository development guide |
Resolve Current Stable Requirements
Read the current installation guide for the selected target. Resolve prerequisites from the selected release's installation sections, support matrix, and package metadata rather than a remembered standalone prerequisites page. Confirm the latest published stable release using release metadata, official releases, and the relevant package registry. Check the target's actual platform assets and package availability, not just a repository version or a pending PR.
What ships with it
8 files 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.

nemo-relay-install is a skill published in the GitHub repository NVIDIA/NeMo-Relay (234 stars, last pushed yesterday), licensed Apache-2.0. It adds 53 tokens to every session and 1,127 once invoked, about $0.0002 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.
