What it does

Sbom Supply Chain Auditor is an agent skill from ptn1411/skill. Audit dependency manifests and lockfiles for SBOM extraction, risky install scripts, unpinned versions, remote/git dependency sources, dependency-confusion and typosquat/known-malicious package names, lockfile integrity gaps, copyleft license risk, and secret-like values.

Its SKILL.md is about 450 tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including scripts and reference files (for example `agents/codex.yaml`, `agents/gemini.yaml` and `agents/openai.yaml`).

It sits in Security, covering Supply chain security. It works with Git. The repository describes itself as: Bộ công cụ và tập hợp skill hỗ trợ phân tích phần mềm, khôi phục cấu trúc nguồn ở mức cần thiết, rà soát bảo mật, kiểm tra phụ thuộc và xây dựng kế hoạch khắc phục cho các hệ…

When your agent uses it

  • Tasks that involve Supply chain security

Example prompts

  • “/sbom-supply-chain-auditor”

Requirements

  • Python 3

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Run python sbom-supply-chain-auditor/scripts/analyze_supply_chain.py --out output/sbom-supply-chain-auditor.
  2. Review findings.json and REPORT.md.
  3. Use findings to prioritize dependency pinning, secret rotation, and package trust review.

What it can do on your machine

Read from SKILL.md and the folder at commit ce2b65e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Sbom Supply Chain Auditor loads about 445 tokens when it runs, and up to ~605 if it reads all its reference files. Until then it costs about 75 tokens; SKILL.md has 155 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~75
When it runs · the whole SKILL.md, loaded when a task matches
~445
With references · SKILL.md plus every file in references/, read only if the agent opens them
~605

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 155 words (~445 tokens).

“Use after source recovery or on application repos to identify dependency and supply-chain risks.”
