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 agent configuration capability warrants a warning because it changes agent guidance and editor configuration, but the inspected operations require an explicit installer selection. The declared postinstall target is absent, and no concrete malicious behavior was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 83.0% - **Started:** 2026-10-12T05:54:19.244Z - **Finished:** 2026-10-12T05:55:19.549Z - **Download time:** 524 ms - **Static scan time:** 774 ms - **AI review time:** 59005 ms - **Total time:** 60305 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:** No confirmed attack was identified. An explicitly selected installer can add package-specific AI-agent guidance and MCP configuration to a project. - **Trigger:** A user runs the installer and selects the agent query or MCP setup option. - **Impact:** These changes affect later agent behavior and configuration, but the inspected code presents them as user-invoked setup. - **Evidence paths:** cli/installer.js, cli/mcp/installer.js - **Review source:** ai\_review - **Reviewed:** 2026-10-12T05:55:19.549Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The query installer may append guidance to AGENTS.md; MCP setup merges a Chemical X server entry into editor configuration. - **Rationale:** The agent configuration capability warrants a warning because it changes agent guidance and editor configuration, but the inspected operations require an explicit installer selection. The declared postinstall target is absent, and no concrete malicious behavior was established. - **Files touched:** AGENTS.md, .cursor/mcp.json, .vscode/mcp.json, package.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 83.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package manifest declares a postinstall command that points to a file absent from the package snapshot., The installer can append a rule directing AI agents to use the package’s query command before broad searches., The installer offers agent-query setup as an explicit interactive choice and runs it only after that choice., MCP setup adds a Chemical X server entry to project editor configuration when invoked., The MCP installer spec confirms the project configuration entry is created by the installer. - **Evidence against:** The agent configuration changes are exposed through an interactive installer choice, rather than code shown running during package installation., The MCP setup writes a named Chemical X server configuration and preserves existing configuration through a merge., The manifest’s postinstall target is absent from the inspected package file list, so its behavior is not present in this snapshot. ## Affected versions and remediation This report applies to @chem-x/starter-kit@26.9.16-41. - Review the evidence and your use of @chem-x/starter-kit@26.9.16-41 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.
