Provenance

Supply chain provenance

Status for the latest visible version.

No SLSA provenance npm registry signatures gitHead linked

Without SLSA provenance there is no cryptographic link between this tarball and the public source — the axios compromise (March 2026) relied on exactly this gap.

Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance publisher-changed AI (provenance): Transition from primer-css to GitHub Actions is consistent with CI/CD automation; SLSA attestation confirms legitimate pipeline publish. ai
typosquat typosquat.levenshtein:yup AI (typosquat): Scoped @primer/mcp package from GitHub's Primer org; Levenshtein match to 'yup' is coincidental and not a typosquat. ai
phantom-deps phantom-dep:@babel/runtime AI (phantom-deps): @babel/runtime is a runtime peer of @babel/plugin-transform-runtime; conventional indirect usage, not a phantom dep concern. ai
