Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
phantom-deps phantom-dep:pino-pretty AI (phantom-deps): pino-pretty is a transport loaded at runtime by pino; not directly imported but required. ai
phantom-deps phantom-dep:@langchain/openai AI (phantom-deps): Optional integration dep; referenced in config/dynamic imports, not static imports. ai
provenance publisher-changed AI (provenance): Transition from desaadi to paul-klein-browserbase is an org-internal handoff within Browserbase; both are established accounts. ai
dependencies unvetted-dep:anthropic AI (dependencies): anthropic@^0.0.0 is declared but confirmed not directly imported (phantom-dep finding accepted). The real Anthropic SDK used is @anthropic-ai/sdk. This stub dependency poses no runtime risk for this package. ai
publish-pattern new-deps-added AI (publish-pattern): @browserbasehq/sdk is the organization's own first-party SDK; adding it to a Browserbase product is expected and low-risk. ai
maintainer-change maintainer-added AI (maintainer-change): Maintainer addition (anirudhkamath) appears to be a legitimate team change within the Browserbase org; publisher paul-klein-browserbase has strong track record and is the package author. ai
maintainer-change maintainer-removed AI (maintainer-change): Removal of three maintainers alongside an addition is consistent with team restructuring at Browserbase; no signs of hostile takeover. ai
phantom-deps phantom-dep:anthropic AI (phantom-deps): anthropic@^0.0.0 is a placeholder/stub dep; actual SDK is @anthropic-ai/sdk. Not directly imported — stable false positive for this package. ai
provenance no-provenance AI (provenance): Established package from known publisher; lack of provenance is common (~88% of npm) and not a risk signal here. ai
phantom-deps phantom-dep:anthropic-ai AI (phantom-deps): anthropic-ai is a compatibility shim, not directly imported. Stable false positive for this package. ai

v3.3.0

3 findings
HIGH Missing gitHead — previous versions had it provenance

This version has no gitHead field linking it to a source commit, but previous versions did. This suggests the publish environment changed. Published by: GitHub Actions.

INFO Has SLSA provenance attestation provenance

Published via CI/CD with Sigstore attestation (predicate: https://slsa.dev/provenance/v1). This is the strongest supply chain integrity signal.
