Supply chain provenance
Status for the latest visible version.
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.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| 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 |

v0.3.1
2 findingsThis version was published by a different npm account than previous versions on 2026-03-06. This could indicate a legitimate maintainer transition or an account compromise.
