Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The manifest names a postinstall script that is absent from the package snapshot. Inspected agent and MCP configuration is activated through explicit CLI setup, and the remaining flagged process and network behavior serves audit, terminal, or license functions. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-12T06:18:27.690Z - **Finished:** 2026-10-12T06:19:04.920Z - **Download time:** 513 ms - **Static scan time:** 941 ms - **AI review time:** 35775 ms - **Total time:** 37230 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 surface was identified. Agent and MCP configuration is available through an explicit project setup flow, and the declared postinstall target is absent from the package snapshot. - **Trigger:** A user explicitly invokes the hook/setup command or runs the project scaffolder. - **Impact:** These actions change the selected project configuration, but inspected source does not show unconsented install-time mutation or a concrete attack. - **Review source:** ai\_review - **Reviewed:** 2026-10-12T06:19:04.920Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The setup flow can add a search directive to an existing AGENTS.md and write project-local MCP configuration. The manifest's postinstall target is not present in the inspected package files. - **Rationale:** The manifest names a postinstall script that is absent from the package snapshot. Inspected agent and MCP configuration is activated through explicit CLI setup, and the remaining flagged process and network behavior serves audit, terminal, or license functions. - **Files touched:** AGENTS.md, .cursor/mcp.json, .vscode/mcp.json, package.json, .cursorrules - **Network endpoints:** chemicalx.xophz.com, mycompassconsulting.com ### Review decision - **Verdict:** Clean - **Confidence:** 84.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json points postinstall to scripts/postinstall.mjs, which is absent from the published file set; no install-time agent configuration implementation is present in the snapshot., The installer exposes agent and MCP configuration through an explicitly invoked wizard, and the CLI reaches it through hook/setup commands., The installer adds its search directive only to an existing AGENTS.md when the user selects the query setup; the scaffold writes project rules only when creating a project., MCP configuration writes project-local Cursor and VS Code files and is invoked by the setup wizard., The MCP test creates those project-local files and checks the configured server entry., The audit preflight uses git status to identify changed files., The terminal child processes open a supplied URL or invoke gum for terminal prompts and display., License validation sends the supplied license key and generated device ID to the configured product API. - **Evidence against:** The manifest declares an install-time postinstall hook, but its target script is absent from this package snapshot., The installer can add AI-agent directives and MCP configuration to a consumer project, but the inspected caller is an explicit setup wizard. ## Affected versions and remediation This report applies to @chemx/starter-kit@26.9.16-668. - Review the evidence and your use of @chemx/starter-kit@26.9.16-668 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.
