sbom

Tools for creating a Software Bill of Materials (SBOM), an inventory of the software components and licenses used by a project. They produce CycloneDX or SPDX records and can export results to CSV for review.

In plain words
What is it for?
Use them to generate release SBOMs, look up licenses for Rust, JavaScript, and Python packages, inspect image SBOMs, and prepare CSV files for stakeholders.
Why use it?
They help identify project dependencies and resolve missing license information before compliance reviews or releases.

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

sbom 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 yesterday.

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.

SBOM Generation and License Resolution

Generate CycloneDX SBOMs, resolve missing licenses, and export to CSV for compliance review.

Overview

The OpenShell SBOM tooling produces source-tree CycloneDX JSON SBOMs using Syft, resolves missing or hash-based licenses by querying public registries (crates.io, npm, PyPI), and exports the results to CSV for stakeholder review.

SBOMs are release artifacts only -- they are generated on demand and not committed to the repository. Output lands in deploy/sbom/output/ (gitignored).

Pushed gateway and supervisor images carry an SPDX SBOM and minimal SLSA provenance as OCI attestations. Branch E2E, Release Dev, and Release Tag image binaries embed cargo-auditable metadata, so their image SBOMs include linked Rust crates.

Prerequisites

  • mise install has been run (installs Syft and other tools)
  • The repository is checked out at the root

Inspecting an Image SBOM

BuildKit uses its default Syft scanner and attaches one SPDX document per platform. Read one without pulling the image:

docker buildx imagetools inspect ghcr.io/nvidia/openshell/gateway:latest \
  --format '{{ json (index .SBOM "linux/amd64").SPDX }}'

Validate the final attestation, requiring a Cargo package for an auditable image:

tasks/scripts/verify-image-sbom.sh ghcr.io/nvidia/openshell/gateway:latest --require-cargo

Inspecting an Auditable Image Binary

Opt into auditable metadata when staging a local image binary:

OPENSHELL_AUDITABLE=1 PREBUILT_ARCH=amd64 \
  tasks/scripts/stage-prebuilt-binaries.sh gateway

Scan the staged binary rather than the source tree:

mise x -- syft \
  "file:deploy/docker/.build/prebuilt-binaries/amd64/openshell-gateway" \
  -o cyclonedx-json

This output is limited to packages Syft discovers from that binary. Use mise run sbom for the broader source-tree license-compliance inventory.

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.

sbom is a skill published in the GitHub repository NVIDIA/OpenShell (8,421 stars, last pushed 2d ago), licensed Apache-2.0. It adds 79 tokens to every session and 1,321 once invoked, about $0.0004 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.
