On npm installation, the package downloads a platform binary, stores it under its package directory, and executes it to refresh and install skills for detected agents. The binary and resulting agent mutations are not included for source review. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 88.0% - **Started:** 2026-08-14T05:51:03.926Z - **Finished:** 2026-08-14T05:51:49.829Z - **Download time:** 776 ms - **Static scan time:** 79 ms - **AI review time:** 45046 ms - **Total time:** 45903 ms ## Security analysis ### Published attack-surface review - **Summary:** On npm installation, the package downloads a platform binary, stores it under its package directory, and executes it to refresh and install skills for detected agents. The binary and resulting agent mutations are not included for source review. - **Trigger:** npm postinstall outside CI unless ARKCLI\_SKIP\_POSTINSTALL=1 - **Impact:** May modify local AI-agent skill/configuration surfaces during installation; exact changes are opaque. - **Evidence paths:** package.json, scripts/postinstall.js, manifest.json, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-14T05:51:49.829Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** verified remote binary bootstrap followed by automatic agent-skill setup - **Rationale:** No direct malicious behavior, secret collection, or exfiltration is present in the inspected JavaScript. However, automatic install-time execution of an opaque remote binary to modify detected AI agents is an unresolved lifecycle risk. - **Files touched:** manifest.json, bin/arkcli-${platform}-${arch}${ext}, skills/ - **Network endpoints:** lf3-static.bytednsdoc.com, github.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** Install lifecycle downloads and executes a platform binary., Postinstall automatically invokes a noninteractive agent-skill installation command., The downloaded binary's agent-config behavior is not source-inspectable in this package. - **Evidence against:** Binary download is constrained to manifest URLs and checked against a bundled SHA-256., README presents agent integration as the CLI's stated product function; no credential harvesting or exfiltration appears in inspected JS. ## Public findings ### 1.
