nvwb-project

nvwb-project is a skill for Claude Code, Codex from brevdev/workshop-build-an-agent. It costs 45 tokens per session (1,330 once invoked), scanned B, original, Apache-2.0.

A guide for working inside an NVIDIA AI Workbench project container, identified by a .project/spec.yaml file. It explains the project layout and how edits, services, and environment changes behave there.

In plain words
What is it for?
It helps inspect the project specification, edit live-mounted code, reach services by name, and understand when environment changes require a rebuild or restart.
Why use it?
It prevents confusion about where files live and which operations must happen inside or outside the container.

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 B, and why

nvwb-project scanned grade B 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 5d ago.

The scan reads SKILL.md. This mod also ships 10 executable files (hooks/cursor-inner-files.sh, hooks/cursor-inner-read.sh, hooks/cursor-inner-shell.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

- **Both scripts run as the `workbench` user (not root)** — any write to a system directory requires `sudo`. This includes `mkdir`, `npm install -g`, writing to `/usr/local/`, etc. Shell redirections (`>`, `>>`) also run

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

- Compose services are reachable by service name (e.g. `curl http://api:8080/`) via the shared `workbench` network

NVIDIA AI Workbench — In-Container Project Awareness

This skill activates when Codex is working inside an AI Workbench project container (detected by .project/spec.yaml existing in or above the current working directory).

Detection

If .project/spec.yaml exists in the project root, this is a Workbench project. Read it first to understand the project's layout, apps, mounts, and resources.

Key Facts

  • The project root is bind-mounted at /project/ inside the container
  • The nvwb CLI is NOT available inside the container — all nvwb commands must run on the user's local machine (the control plane)
  • This container may be running locally or on a remote — it does not matter for in-container work; the project files are always at /project/
  • Code in layout directories is live-mounted — edits take effect immediately
  • The environment variable AI_WORKBENCH_FLAG=true may be set to detect Workbench context
  • Compose services are reachable by service name (e.g. curl http://api:8080/) via the shared workbench network

What's Safe to Edit

Freely editable — no action needed:

  • Any files in layout directories (code/, data/, models/ or custom paths from spec.yaml)
  • Application code, scripts, notebooks

Requires rebuild — inform user to run nvwb build on the host:

  • apt.txt — system packages
  • requirements.txt — pip packages
  • preBuild.bash — pre-install build script
  • postBuild.bash — post-install build script

Requires restart — inform user to run nvwb close then nvwb open on the host:

  • variables.env — runtime environment variables
  • Mount configuration changes in .project/spec.yaml
  • App definitions in .project/spec.yaml

Edit carefully — validate format:

  • .project/spec.yaml — do not break YAML structure; suggest nvwb validate project-spec after changes

When Informing the User

After editing a build-time or runtime file, always tell the user what action is needed. Examples:

I've updated requirements.txt to add the transformers package. You'll need to run nvwb build on the host to rebuild the container with this change.

What ships with it

12 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.

Changes

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.

nvwb-project is a skill published in the GitHub repository brevdev/workshop-build-an-agent (133 stars, last pushed 17d ago), licensed Apache-2.0. It adds 45 tokens to every session and 1,330 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
