Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 26.9.13-272 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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 source shows explicit project scaffolding that writes agent-facing configuration and remotely fetched files, creating a real but user-invoked capability risk. No automatic lifecycle trigger or concrete malicious behavior was established, so a warning is appropriate. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-12T06:53:56.758Z - **Finished:** 2026-10-12T06:54:30.818Z - **Download time:** 260 ms - **Static scan time:** 506 ms - **AI review time:** 33293 ms - **Total time:** 34060 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 scaffolding can add Cursor guidance and remotely supplied starter files to a project. This is a user-invoked capability; the inspected source does not establish an active attack. - **Trigger:** A user runs chemx create or invokes the create-chemx command. - **Impact:** The generated files and rules may affect the project and its AI coding assistant, but no unconsented or install-time mutation was found. - **Review source:** ai\_review - **Reviewed:** 2026-10-12T06:54:30.818Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The scaffold requests starter files from a configurable service and writes them into the selected directory; it also creates a Cursor rules file if absent. - **Rationale:** The source shows explicit project scaffolding that writes agent-facing configuration and remotely fetched files, creating a real but user-invoked capability risk. No automatic lifecycle trigger or concrete malicious behavior was established, so a warning is appropriate. - **Files touched:** cli/index.js, cli/scaffold.js, cli/license.js - **Network endpoints:** chemicalx.xophz.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package exposes a CLI through the chemx and create-chemx commands., Scaffolding runs only through explicit CLI commands and obtains a license before proceeding., The scaffold writes a Cursor rules file containing project guidance when one is absent., The scaffold also downloads starter-kit files and writes them into the selected project directory., No install lifecycle hook is declared in the manifest., Browser launching and shell-based build execution are user-invoked utility behavior; no malicious use was established. - **Evidence against:** The scaffold’s generated Cursor rules can influence an AI coding assistant in the target project., The starter-kit contents come from a configurable remote service and are written into the project without source-side content validation. ## Affected versions and remediation This report applies to chemx@26.9.13-272. - Review the evidence and your use of chemx@26.9.13-272 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.
