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 postinstall hook performs a real, scoped deletion of consumer dependencies, creating a destructive install-time risk. The peer dependency declarations suggest a possible compatibility rationale, so the evidence supports a warning rather than a publish block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-09T06:13:01.754Z - **Finished:** 2026-10-09T06:13:31.956Z - **Download time:** 1293 ms - **Static scan time:** 482 ms - **AI review time:** 28426 ms - **Total time:** 30202 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 postinstall hook removes the consumer project's React package directories. This can break applications that depend on those installed packages. - **Trigger:** Installing the package runs its postinstall hook. - **Impact:** React and React DOM may be removed from the consuming project. - **Evidence paths:** package.json - **Review source:** ai\_review - **Reviewed:** 2026-10-09T06:13:31.956Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook runs rm -rf on node\_modules/react and node\_modules/react-dom, suppressing errors. - **Rationale:** The postinstall hook performs a real, scoped deletion of consumer dependencies, creating a destructive install-time risk. The peer dependency declarations suggest a possible compatibility rationale, so the evidence supports a warning rather than a publish block. - **Files touched:** node\_modules/react, node\_modules/react-dom ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The postinstall script recursively deletes the consuming project's node\_modules/react and node\_modules/react-dom directories., React and React DOM are declared peer dependencies, suggesting the cleanup may be intended to affect dependency resolution, but the install hook can still remove packages from the consumer. ## Affected versions and remediation This report applies to @1interface/chat-core@0.20.3. - Review the evidence and your use of @1interface/chat-core@0.20.3 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.
