Sensitive capabilities are activated during normal CLI use rather than package installation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 87.0% - **Started:** 2026-09-01T18:04:05.281Z - **Finished:** 2026-09-01T18:06:31.996Z - **Download time:** 1279 ms - **Static scan time:** 11315 ms - **AI review time:** 134119 ms - **Total time:** 146715 ms ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface was established. Sensitive capabilities are activated during normal CLI use rather than package installation. - **Trigger:** A user runs the CLI and explicitly invokes relevant features. - **Impact:** No unconsented install-time mutation or confirmed malicious data exfiltration was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-01T18:06:31.996Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User-invoked coding CLI features and a missing-parser fallback. - **Rationale:** The package has no registry-install lifecycle hook, and the flagged command and network primitives are attributable to runtime CLI features. Static inspection found no concrete malicious payload, persistence, credential theft, or install-time attack chain. ### Review decision - **Verdict:** Clean - **Confidence:** 87.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for:** The manifest exposes a CLI and only has a publish-time prepublishOnly script, not an install lifecycle hook., The bundled SDK has a runtime fallback that downloads a missing tree-sitter WebAssembly parser with curl., The open-file UI action starts a configured editor command through a shell., The common spawn declaration is only a TypeScript type and does not execute commands. - **Evidence against:** No preinstall, install, postinstall, or prepare hook is declared., The download fallback is for a named parser asset and is not install-time execution., The shell launch is reached from an explicit open-file action., No source evidence showed credential harvesting, stealth persistence, destructive behavior, or an attacker-controlled payload chain. ## Public findings ### 1.
