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 CLI setup that modifies agent-facing project configuration, which warrants a warning under the agent capability policy. The declared postinstall points to a file absent from the inspected package snapshot, and the inspected agent configuration writes are not shown to run through it. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-10-12T08:08:57.252Z - **Finished:** 2026-10-12T08:09:40.306Z - **Download time:** 261 ms - **Static scan time:** 852 ms - **AI review time:** 41941 ms - **Total time:** 43054 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 package provides explicit setup commands that change project agent configuration. The query setup adds an instruction directing AI agents to use the package's search command; the MCP setup registers its server in editor configuration. - **Trigger:** A user invokes the CLI setup wizard or MCP installation command and selects the relevant setup. - **Impact:** These changes can shape later agent behavior and enable the configured MCP server in those editors. No unconsented install-time agent configuration mutation was established. - **Evidence paths:** cli/installer.js, cli/mcp/installer.js - **Review source:** ai\_review - **Reviewed:** 2026-10-12T08:09:40.306Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The query installer appends an instruction to AGENTS.md, while the MCP installer writes a named server entry to project Cursor and VS Code configuration files. - **Rationale:** The source shows explicit CLI setup that modifies agent-facing project configuration, which warrants a warning under the agent capability policy. The declared postinstall points to a file absent from the inspected package snapshot, and the inspected agent configuration writes are not shown to run through it. - **Files touched:** cli/installer.js, cli/mcp/installer.js, cli/mcp/installer.spec.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package exposes a CLI and declares an install-mcp command alongside a postinstall script., The explicit installer wizard offers an agent query setup that adds an instruction to AGENTS.md telling AI agents to use the package's search command., The MCP installer writes its server configuration into project Cursor and VS Code configuration files., The package snapshot does not contain the postinstall script's referenced scripts/postinstall.mjs file. - **Evidence against:** The agent configuration writes are performed by explicit CLI setup flows, rather than by the declared npm postinstall hook., The MCP installer adds a named server configuration and preserves or merges the existing configuration. ## Affected versions and remediation This report applies to create-chemx@26.9.16-668. - Review the evidence and your use of create-chemx@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.
