awesome-agv: Skill for Claude Code

.agents/skills/supply-chain-security/SKILL.md

supply-chain-security is a skill for Claude Code, Codex from irahardianto/awesome-agv. It costs 29 tokens per session (682 once invoked), scanned A, original, MIT.

A guide to securing the software supply chain: the code, libraries, and build artifacts used to create and ship software. It covers dependency vulnerability checks, software bills of materials, license reviews, and artifact verification.

In plain words
What is it for?
It is for auditing dependencies, adding vulnerability scans to CI, generating software bills of materials, and checking licenses.
Why use it?
It helps teams find vulnerable or unsuitable dependencies and detect risks introduced through third-party packages.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is irahardianto/awesome-agv's own configuration. It tells Claude Code and Codex how to work on awesome-agv itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything awesome-agv configures →

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

supply-chain-security 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 7d 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.

Supply Chain Security Principles

Guidelines for securing the software supply chain.

When to Invoke

  • Auditing project dependencies
  • Setting up CVE scanning in CI/CD
  • License compliance review
  • Responding to supply chain vulnerability disclosures

Dependency Security

CVE Scanning

Language Tool Command
Go govulncheck govulncheck ./...
Rust cargo audit cargo audit
Python pip-audit pip-audit
Node.js npm audit npm audit
Java OWASP Dependency-Check mvn dependency-check:check
.NET Built-in dotnet list package --vulnerable
Ruby bundle audit bundle audit check --update
PHP composer audit composer audit

Scanning Frequency

  • Every CI run — fail build on critical/high CVEs
  • Weekly scheduled scan — catch newly disclosed vulnerabilities
  • On dependency update — verify new version is clean

SBOM (Software Bill of Materials)

Generation

# CycloneDX format (recommended)
# Go
cyclonedx-gomod mod -json -output sbom.json

# Node.js
npx @cyclonedx/cyclonedx-npm --output-file sbom.json

# Python
cyclonedx-py poetry --format json -o sbom.json

Usage

  • Attach SBOM to releases
  • Track all transitive dependencies
  • Enable downstream vulnerability analysis

License Compliance

Risk Levels

License Risk Action
MIT, BSD, Apache 2.0 Low Permissive — generally safe
LGPL Medium Review linking requirements
GPL High Copyleft — may require source disclosure
AGPL Critical Network copyleft — consult legal
No license Critical Cannot use — no rights granted

Automation

  • Use license-checker (Node.js), pip-licenses (Python), cargo-license (Rust)
  • Maintain allowlist/denylist of approved licenses
  • Fail CI on disallowed licenses

Supply Chain Attack Prevention

  1. Lock files committedpackage-lock.json, go.sum, Cargo.lock, poetry.lock
  2. Pin exact versions in production — no floating ranges
  3. Verify checksums — lock files contain integrity hashes
  4. Review new dependencies — check maintainer, downloads, last commit, open issues
  5. Minimal dependencies — each dep = increased attack surface
  6. Signed commits and releases — verify artifact provenance

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.
