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. LPM treats this as warn-only first-party agent extension lifecycle risk. Installing the package automatically changes Cursor's global skill configuration. The change is confined to package-owned and legacy namespaces, but it makes bundled instructions globally active. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-09-11T13:46:56.406Z - **Finished:** 2026-09-11T13:48:17.651Z - **Download time:** 1267 ms - **Static scan time:** 10850 ms - **AI review time:** 69125 ms - **Total time:** 81245 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:** Installing the package automatically changes Cursor's global skill configuration. The change is confined to package-owned and legacy namespaces, but it makes bundled instructions globally active. - **Trigger:** npm installs the package as a consumer dependency or through npx. - **Impact:** Future Cursor sessions can receive package-provided global instructions; stale skills in the package namespace and the legacy namespace can be deleted. - **Evidence paths:** package.json, scripts/install-cursor-skills.mjs, dist/internal/install-cursor-skills.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T13:48:17.651Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall copies and rewrites Cursor skill files as always-apply rules. - **Rationale:** This is a first-party agent-extension lifecycle risk rather than confirmed malware. Automatic global instruction installation warrants a warning because it changes AI-agent behavior without an explicit setup command. - **Files touched:** ~/.cursor/skills/agentsdk/\/SKILL.md, ~/.cursor/skills/agentkit/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs an automatic postinstall hook., The hook installs bundled skills into the user's Cursor skills directory during consumer installs., Installed skill files are rewritten as always-apply global rules, and stale package namespaces are removed. - **Evidence against:** The mutation is limited to the package's agentsdk namespace and a named legacy namespace., No self-dependency, credential exfiltration, remote payload loading, or unrelated network action was found in the inspected lifecycle path., The other flagged files implement named CLI, OAuth, documentation, and update-check features rather than an install-time payload. ## Affected versions and remediation This report applies to @cursor/july@0.1.108. - Review the evidence and your use of @cursor/july@0.1.108 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.
