Lifecycle scriptscaution

A prepare install-time script adds execution during installation; its purpose is not shown here, so it is a modest supply-chain and reproducibility concern.

Maintainerscaution

Only one registry account has publish access, creating limited publishing redundancy, although the repository shows ongoing project activity.

Project backingcaution

The repository is owned by an individual rather than an organization, so the single registry maintainer represents limited visible project backing.

Repo commit activitycaution

No commits and no active maintainers were recorded in the last three months, a maintenance concern that conflicts with the recent release and pull-request activity.

Repo toolingcaution

The repository uses TypeScript, Rollup, Vitest, and npm scripts for builds and tests; no security scanning tool was detected, which is a minor hygiene gap.
