Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The install-triggered refresh is first-party agent skill setup consistent with the stated product, but its behavior is implemented in an unavailable binary. This warrants a warning for unresolved agent extension lifecycle risk; the inspected JavaScript does not establish broader or malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-10-09T20:52:12.116Z - **Finished:** 2026-10-09T20:53:18.985Z - **Download time:** 752 ms - **Static scan time:** 126 ms - **AI review time:** 65991 ms - **Total time:** 66869 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:** The install hook downloads and installs the CLI binary, then automatically invokes its skill refresh command. The binary is outside the inspected source, so the scope of changes made by refresh is unresolved. - **Trigger:** Package installation runs the postinstall hook. - **Impact:** The refresh may change supported local agent skill files; source inspection cannot establish its exact effects. - **Evidence paths:** package.json, scripts/postinstall.js, manifest.json - **Review source:** ai\_review - **Reviewed:** 2026-10-09T20:53:18.985Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook downloads a platform binary and calls it with +connect --refresh without interaction. - **Rationale:** The install-triggered refresh is first-party agent skill setup consistent with the stated product, but its behavior is implemented in an unavailable binary. This warrants a warning for unresolved agent extension lifecycle risk; the inspected JavaScript does not establish broader or malicious behavior. - **Files touched:** scripts/postinstall.js, manifest.json - **Network endpoints:** https://sf16-sg.tiktokcdn.com/obj/eden-sg/psjryh/ljhwZthlaukjlkulzlp/prod/1.0.32/arkcli-1.0.32-darwin-amd64 ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The postinstall hook installs a downloaded executable and runs its skill refresh command automatically., That refresh command is non-interactive, and the binary’s effects are not inspectable in this source snapshot. - **Evidence against:** The package describes itself as a BytePlus Ark CLI that provides agent skills., The download source is in the manifest, and the installer checks the binary against the expected SHA-256 digest. ## Affected versions and remediation This report applies to @byteplus/ark-cli@1.0.32. - Review the evidence and your use of @byteplus/ark-cli@1.0.32 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.
