Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The flagged token flow is conditional on remote skill resolution during generation and is documented as authentication to the skills.sh API. GitHub credentials go to GitHub for repository lookups, and the package has no install-time hook. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-11-01T12:20:19.996Z - **Finished:** 2026-11-01T12:21:17.474Z - **Download time:** 1275 ms - **Static scan time:** 1433 ms - **AI review time:** 54767 ms - **Total time:** 57478 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No attack was identified; the reviewed credential use supports documented remote skill resolution. - **Trigger:** A generation resolves configured remote skill references that are not already stored. - **Impact:** No malicious impact identified in the reviewed flows. - **Review source:** ai\_review - **Reviewed:** 2026-11-01T12:21:17.474Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The resolver authenticates to skills.sh with Vercel OIDC when available, then falls back to public GitHub; a configured GitHub token is used for GitHub API lookups. - **Rationale:** The flagged token flow is conditional on remote skill resolution during generation and is documented as authentication to the skills.sh API. GitHub credentials go to GitHub for repository lookups, and the package has no install-time hook. - **Network endpoints:** skills.sh, api.github.com, raw.githubusercontent.com ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The README describes remote skills.sh resolution through its authenticated API when Vercel OIDC is available, with public GitHub as a fallback., The Vercel OIDC token is read only in the remote skill resolver and sent as a bearer token to skills.sh for that lookup., The resolver is called while processing a generation whose skills have not already been resolved., GitHub tokens, when configured, are sent to api.github.com for GitHub repository lookups. - **Evidence against:** Remote skill resolution forwards VERCEL\_OIDC\_TOKEN to skills.sh; this is a cross-service credential flow, but the package documents it as authentication for that feature., The manifest has prepack and prepublishOnly scripts, but no install-time lifecycle hook. ## Affected versions and remediation This report applies to @viby/sdk@0.3.17. - Review the evidence and your use of @viby/sdk@0.3.17 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
