A reusable React hook and utility package for real-time webcam background switching and blurring using [MediaPipe Selfie Segmentation](https://google.github.io/mediapipe/solutions/selfie_segmentation.html). This package provides the core logic and compositing, allowing you to build your own custom UI in React, Next.js, or any modern frontend framework.
Cursor Rules are .cursorrules / .cursor/rules files that steer Cursor's AI; scanned with the same pipeline.
We found this by crawling public sources and nobody has attested to it. That is how most of the registry gets here, and it is not a mark against the artifact — it only means no authenticated act of publication is on record. An artifact can be the vendor's own and still appear here.
9 critical findings reported by trivy, osv-scanner, 0 of them in the installed artifact. The composite score alone does not reflect this — read the per-scanner reports below.
Cursor Rules are .cursorrules / .cursor/rules files that steer Cursor's AI. Review the scanned source before copying them into your own project.

7 of 11 scanners examined this package. The rest do not apply to it — language, ecosystem and packaging decide which analyzers can say anything, and a scanner that cannot examine an artifact reports nothing rather than passing it.

Findings in files this artifact installs stand as reported; a model re-read the rest and said which ones it believes are false positives. This is a second opinion published beside the evidence, not a correction to it: the per-scanner reports above are unchanged, every dismissed finding is still listed there at its original severity, and the score and the Caution badge are computed from those raw severities alone. Nothing below moved them.
Out of 295 findings across every scanner that examined this package. 9 of 9 findings rated critical by their scanner were among the dismissals.
Not reviewed is not the same as clean. Those 70 findings stand exactly as their scanners reported them, at full severity, as they would have without this review.
Two keys had to turn. The model had to name a reason from a fixed list of six, and a deterministic check of ours — over which files this artifact actually installs — had to independently agree. Anything it could not corroborate is in “not reviewed” above, at full severity.
221 Documentation or example — The match is in documentation or sample code, confirmed by our own check to be outside the installed artifact.

These findings are in files this artifact installs and are not placeholder values. No false-positive basis can be corroborated for such a finding, so this review never dismisses one; they were not sent to the model and stand at their scanner's severity.

High severity findings require review
The artifact contains 4 findings about installed code, with 2 requiring immediate attention. A high severity finding indicates low analyzability of the repository, which may obscure further risks. Additionally, a high severity vulnerability (CVE-2026-44573) is present in `examples/nextjs-demo/package-lock.json`.
Concern level assessed by the review: High. This is the review's scale, not the registry badge.
Reviewed by gemini-2.5-flash. The model sees the findings, not your code, and cannot change a score.
