Process execution is limited to explicit analysis and development-tool actions. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 94.0% - **Started:** 2026-09-01T04:21:38.202Z - **Finished:** 2026-09-01T04:24:02.839Z - **Download time:** 503 ms - **Static scan time:** 7270 ms - **AI review time:** 136862 ms - **Total time:** 144637 ms ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface was established. Process execution is limited to explicit analysis and development-tool actions. - **Trigger:** A user explicitly runs the CLI, migration feature, or development repository-analysis script. - **Impact:** The tools can read selected source projects and produce requested analysis output; no exfiltration or install-time action was confirmed. - **Review source:** ai\_review - **Reviewed:** 2026-09-01T04:24:02.839Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Local static analysis and explicit Git or diagnostics subprocesses. - **Rationale:** The high-risk scanner labels are not supported by the inspected source: there is no install hook, credential handling, unofficial gateway, or exfiltration path. The child-process and repository-cloning code is explicit tooling consistent with a static analyzer. ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for:** The CLI imports child-process spawning for its user-invoked command-line functionality., The migration feature imports child-process support to inspect Git references., The rules bundle invokes the installed Effect TypeScript diagnostics tool., A separately run development script clones a fixed list of public repositories and launches the local CLI. - **Evidence against:** The manifest has no preinstall, install, or postinstall lifecycle hook., No source-backed credential collection, gateway redirection, or command-output exfiltration was found., The inspected command execution is package-aligned analysis, diagnostics, or explicit repository tooling., No persistence, destructive consumer-project mutation, or relevant runtime network endpoint was established. ## Public findings ### 1.
