sbom is a skill for Claude Code from ysfAskri/archguardian. It costs 15 tokens per session (211 once invoked), scanned A, original, MIT.

A Software Bill of Materials, or SBOM, listing the third-party components in a project. It can produce CycloneDX or SPDX documents for projects using npm, Go, Rust, or Java dependencies.

In plain words
What is it for?
Use it to generate or save a dependency inventory in CycloneDX or SPDX 2.3 format.
Why use it?
It creates a standard inventory of dependencies that can be reviewed or shared with security and compliance processes.

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 6d 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.

What it actually says

archguardian sbom

Generate a Software Bill of Materials listing all project dependencies.

Instructions

  1. Run the SBOM command:
    npx archguardian sbom --format cyclonedx $ARGUMENTS
    
    Or use --format spdx for SPDX 2.3 format.
  2. Present the output or save to a file.
  3. Explain the SBOM contents: number of components, ecosystems covered.

Tips

  • Supports npm (package.json), Go (go.mod), Rust (Cargo.toml), and Java (pom.xml).
  • CycloneDX 1.5 includes PURLs for each component.
  • SPDX 2.3 is compatible with NTIA minimum SBOM requirements.
  • Pipe output to a file: npx archguardian sbom --format cyclonedx > sbom.json

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.
