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 area. It can overwrite package-namespaced skills and remove legacy skills. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-08T00:31:56.149Z - **Finished:** 2026-09-08T00:33:27.964Z - **Download time:** 1018 ms - **Static scan time:** 9098 ms - **AI review time:** 81697 ms - **Total time:** 91815 ms The recorded confidence comes from the underlying analysis.

It can overwrite package-namespaced skills and remove legacy skills. - **Trigger:** npm installation or npx execution that runs postinstall. - **Impact:** The package can alter the instructions applied to Cursor coding agents without an explicit setup command. - **Evidence paths:** package.json, dist/internal/install-cursor-skills.js - **Review source:** ai\_review - **Reviewed:** 2026-09-08T00:33:27.964Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic installation of global Cursor skills. - **Rationale:** This is a package-aligned but automatic global AI-agent configuration change, which warrants a warning under the lifecycle policy. The inspected source does not establish malware behavior. - **Files touched:** ~/.cursor/skills/agentsdk/\/SKILL.md, ~/.cursor/skills/agentkit ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** An automatic postinstall hook runs the skill installer during package installation., The installer writes package skills into the user's Cursor skills directory and overwrites existing package-namespaced skills., It deletes unshipped entries in that namespace and deletes the legacy agentkit namespace., Installed skills are marked alwaysApply, making them global Cursor rules. - **Evidence against:** The installer is limited to the package's Cursor skill namespaces and skips non-consumer checkouts., No install-time network request, credential harvesting, self-dependency, or remote payload execution was found., The dynamic import is used to load the package's local installer; runtime network features are command- and configuration-driven. ## Affected versions and remediation This report applies to @cursor/july@0.1.101. - Review the evidence and your use of @cursor/july@0.1.101 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. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node -e "try{const p='./scripts/install-cursor-skills.mjs';if(require('fs').existsSync(p))require('child_process').execFileSync(process.execPath,[p],{stdio:'inherit'})}catch{}" ``` ### 2. Critical: Red Install Lifecycle Script - **Category:** Manifest - **Confidence:** 95.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script matches a deterministic static-gate block pattern. Public source snippet (untrusted): ```json scripts.postinstall = node -e "try{const p='./scripts/install-cursor-skills.mjs';if(require('fs').existsSync(p))require('child_process').execFileSync(process.execPath,[p],{stdio:'inherit'})}catch{}" ``` ### 3.

Medium: Dynamic Require - **Category:** Source - **Confidence:** 75.0% - **Path:** dist/internal/authored-loaders.js - **Public source:** [View source]() Package source references dynamic require/import behavior. Public source snippet (untrusted): ```javascript L44: * L45: * Node caches `import()` by URL for the life of the process, so a long-lived L46: * `agent-sdk dev` would otherwise keep serving the first load of eval files ``` ### 6. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 7. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 8.

Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 11. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 12. Low: No License - **Category:** Manifest - **Confidence:** 80.0% Package manifest does not declare a clear license. ### 13. High: Semantic Analysis Limited - **Category:** Scanner Coverage - **Confidence:** 100.0% - **Path:** dist/channels.js - **Public source:** [View source]() A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review.
