rust-supply-chain-attestation skillA

rust-supply-chain-attestation is agent-read markdown (skill) from sparq-org/sparq: How sparq attests its Rust/cargo supply chain — cargo-deny (advisories/bans/licenses/sources), cargo-vet/cargo-auditable, CycloneDX SBOM + VEX, SLSA build provenance, and OpenSSF Scorecard — and which evidence each tool produces for the SBOM, SLSA, NIST SSDF, EU CRA, and OpenSSF certification frameworks. Use when working any of the sbom/slsa/ssdf/cra/openssf certification worktrees, when adding or changing a supply-chain CI lane, when filling out an SBOM/VEX or a SLSA-level claim, or when asked .

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add sparq-org/sparq/rust-supply-chain-attestation@git:20260728.4beba52
Exact content
mdr add sparq-org/sparq/rust-supply-chain-attestation@sha256:72779d802ef35d2c

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
