sbom-analysis

sbom-analysis is a skill for Claude Code, Codex from UnitOneAI/SecuritySkills. It costs 89 tokens per session (5,816 once invoked), scanned A, original, MIT.

A review of a Software Bill of Materials (SBOM), which is a list of the components and dependencies inside a software product. It also interprets VEX documents, which explain whether reported vulnerabilities actually affect those components.

In plain words
What is it for?
Checking CycloneDX or SPDX SBOMs, reviewing software supply-chain risk, interpreting CSAF VEX records, assessing vulnerability exposure, and finding license conflicts.
Why use it?
It helps reveal missing inventory details, risky indirect dependencies, exploitable vulnerabilities, and incompatible software licenses. This avoids treating every listed vulnerability as equally urgent.

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-analysis 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 5d 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.

SBOM Analysis & VEX Review -- CycloneDX 1.5 / SPDX 2.3 / VEX (CSAF) / NTIA Minimum Elements

Frameworks: CycloneDX 1.5 (OWASP), SPDX 2.3 (Linux Foundation / ISO 5962), VEX via CSAF 2.0 (OASIS), NTIA SBOM Minimum Elements Role: Security Engineer, AppSec Engineer Time: 20-40 min Output: SBOM completeness assessment, VEX status summary, dependency risk analysis, and license conflict report


When to Use

If a target is provided via arguments, focus the review on: $ARGUMENTS

Use this skill when an SBOM file (CycloneDX or SPDX format) is shared for review, when evaluating software supply chain risk for a vendor or internal application, when VEX documents need interpretation to determine actual exploitability, when assessing SBOM completeness for regulatory compliance (EO 14028, EU CRA), or when performing transitive dependency analysis for known vulnerabilities.

Do not use when: The task is triaging a specific CVE without SBOM context (use cve-triage), performing runtime vulnerability scanning (use scanner-tuning), or reviewing source code for security flaws (use secure-code-review).


Context the Agent Needs

Before starting, collect or confirm:

  • SBOM file(s): The actual SBOM document(s) in CycloneDX (JSON/XML) or SPDX (JSON/RDF/tag-value) format
  • SBOM format and version: CycloneDX 1.5, SPDX 2.3, or other (identify version explicitly)
  • VEX document(s): Associated VEX statements, if available (CSAF 2.0 format, CycloneDX VEX, or OpenVEX)
  • Software identity: Name, version, and vendor of the software the SBOM describes
  • Intended use context: Is this SBOM for procurement evaluation, compliance audit, incident response, or continuous monitoring?
  • Compliance requirements: Applicable mandates (EO 14028 for US federal suppliers, EU Cyber Resilience Act, FDA premarket guidance for medical devices)
  • License policy: Organization's approved/prohibited license list, if applicable
  • Known vulnerability data: CVE data sources to cross-reference (NVD, OSV, GitHub Advisory Database)

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-analysis is a skill published in the GitHub repository UnitOneAI/SecuritySkills (58 stars, last pushed 2mo ago), licensed MIT. It adds 89 tokens to every session and 5,816 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.
