scorecard-checks

scorecard-checks is a skill for Claude Code from sbom-tool/gh-guard. It costs 19 tokens per session (2,554 once invoked), scanned A, original, MIT.

A guide to the OpenSSF Scorecard, a tool that rates the security practices of open-source projects across 18 checks. It focuses on how to apply those checks to Rust projects.

In plain words
What is it for?
Use it to review or improve a Rust project's Scorecard checks, including security policy, licensing, fuzzing, vulnerability scanning, workflow safety, and branch protection.
Why use it?
It turns a broad security review into a checklist of project files, settings, and workflows. This helps reveal missing protections in areas such as dependency updates, code review, CI, and GitHub Actions permissions.

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

scorecard-checks 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 9d 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.

Detailed Check Guidance

1. Security-Policy (Easy — 10/10)

What it checks: Presence of SECURITY.md in repo root or .github/. Rust action: Use the templates/SECURITY.md template. Include coordinated disclosure policy and supported versions table.

2. License (Easy — 10/10)

What it checks: Recognized license file in repo root. Rust action: Add LICENSE (MIT or Apache-2.0 are standard for Rust). Ensure Cargo.toml has matching license = "MIT".
