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. Static inspection found explicit CLI setup that writes first-party agent instructions and MCP configuration, a warning-level agent capability. The declared postinstall target is absent, and no lifecycle-triggered attack was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-12T08:08:57.109Z - **Finished:** 2026-10-12T08:09:50.952Z - **Download time:** 518 ms - **Static scan time:** 738 ms - **AI review time:** 52587 ms - **Total time:** 53843 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:** Explicit setup can add Chemical X instructions to an existing AGENTS.md and register its MCP server in editor configuration. This is a guarded, package-owned agent integration; no active attack was established. - **Trigger:** A user runs the CLI hook/setup wizard or install-mcp command and selects setup. - **Impact:** The setup changes how configured agents discover code and enables them to launch the Chemical X MCP command. - **Review source:** ai\_review - **Reviewed:** 2026-10-12T08:09:50.952Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The wizard can append a directive steering agents to use the package query command; MCP setup writes the named server configuration for Cursor, VS Code, and, when present, Antigravity. - **Rationale:** Static inspection found explicit CLI setup that writes first-party agent instructions and MCP configuration, a warning-level agent capability. The declared postinstall target is absent, and no lifecycle-triggered attack was established. - **Files touched:** AGENTS.md, .cursor/mcp.json, .vscode/mcp.json, ~/.gemini/config/mcp\_config.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The interactive installer offers an option that writes a query directive into an existing AGENTS.md, instructing agents to use this package’s search command., The CLI exposes that installer through explicit hook/setup commands, and the installer presents target choices before making changes., The MCP setup adds a named Chemical X server to Cursor and VS Code project configuration; its fallback runs \`npx -y chemx mcp\`., Antigravity configuration is also an installer operation and is skipped unless its expected config directory exists. - **Evidence against:** The manifest names a postinstall script, but the referenced scripts/postinstall.mjs file is absent from the inspected package snapshot., The inspected agent configuration changes are reachable through explicit CLI setup flows, not through an automatic lifecycle hook. ## Affected versions and remediation This report applies to create-chemx@26.9.16-41. - Review the evidence and your use of create-chemx@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.
