nvcf: Instructions file for Codex

AGENTS.md

nvcf AGENTS.md is an instructions file for Codex, OpenCode from NVIDIA/nvcf. It costs 5,525 tokens per session, scanned A, original, Apache-2.0.

A coding-agent guide for NVCF, NVIDIA Cloud Functions, a system for running cloud-based functions. It explains the repository layout, shared code from other repositories, ownership files, tools, documentation, and local testing rules.

In plain words
What is it for?
Use it when modifying NVCF services, infrastructure, migrations, tools, tests, documentation, or imported repository snapshots.
Why use it?
It helps an agent navigate a large repository and avoid mistakes with pinned external code, subtree ownership, Python commands, and test environments.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is NVIDIA/nvcf's own configuration. It tells Codex and OpenCode how to work on nvcf itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything nvcf configures →

About the project

NVIDIA Cloud Functions is a platform for deploying, managing, and running GPU-based workloads such as inference, streaming, and batch processing, while routing requests to GPU worker clusters. Its monorepo contains the service code, deployment materials, documentation, examples, command-line tools, agent skills, and validation tools used to build and operate the platform.

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

nvcf AGENTS.md 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 10d 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.

Repo Layout

This repo is an umbrella layout: upstream services appear as ordinary directories arranged under src/, deploy/, infra/, and migrations/ according to imports.yaml. Goal: over time, land and maintain code here natively while upstream-owned sources are still tracked by commit pin. Tooling lives under tools/ and tests/.

Use python3, not python, when Python is needed. Use the nearest nested AGENTS.md for subtree-specific guidance.

Useful pointers:

  • BAZEL.md for the contributor-facing Bazel build path
  • docs/AGENTS.md for in-repo user and developer documentation
  • tools/AGENTS.md for repo tooling
  • tests/bdd/AGENTS.md for behavior-driven development (BDD) scenarios and suite rules
  • src/libraries/rust/stargate/AGENTS.md for mandatory Stargate mock and performance validation, including related chart, deployment, benchmark, and CI changes
  • imports.yaml for subtree ownership and commit pins
  • .cursor/skills/documentation-style/SKILL.md for docs style
  • .cursor/skills/ for root dev-skill symlink fanout
  • ai-tooling/user/skills/ and ai-tooling/dev/skills/ for public skills

If a referenced skill is outdated, update it before finishing.

Cross-repo and stack routing

Documentation is monorepo-native. User docs, version catalogs, and Fern navigation are owned under docs/ and fern/ in this repository. Do not route documentation changes through an external documentation repository or an external workspace index. Start with docs/AGENTS.md and the nearest nested guidance.

Use imports.yaml to decide whether a subtree is monorepo-native or still owned by an upstream repo. Native subprojects are edited here. Upstream-owned subtrees usually need the change in the upstream repo and a later commit-pin update.

For self-managed stack ownership, deployment order, chart/image-source mapping, or "which subtree owns this" questions, use:

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.
