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 skills area. It overwrites package-owned skill copies and removes entries in its namespace and a legacy namespace. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-09-08T00:31:55.820Z - **Finished:** 2026-09-08T00:33:24.763Z - **Download time:** 1517 ms - **Static scan time:** 8920 ms - **AI review time:** 78503 ms - **Total time:** 88943 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 skills area. It overwrites package-owned skill copies and removes entries in its namespace and a legacy namespace. - **Trigger:** npm install or npx installation of the package as a consumer dependency - **Impact:** Package-provided instructions can be automatically loaded into Cursor sessions; existing package-owned and legacy skill directories can be removed. - **Evidence paths:** package.json, scripts/install-cursor-skills.mjs, src/internal/install-cursor-skills.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-08T00:33:24.763Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall copies and rewrites globally applied Cursor skills. - **Rationale:** The automatic global Cursor-skill mutation is a real lifecycle risk and warrants a warning under the policy for first-party agent extension setup. The inspected installer is namespace-scoped and contains no confirmed exfiltration or remote execution. - **Files touched:** scripts/install-cursor-skills.mjs, src/internal/install-cursor-skills.ts, skills/, ~/.cursor/skills/agentsdk/, ~/.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 postinstall hook silently launches a package installer., On consumer installs, the installer copies shipped skills into the user's Cursor skills directory., The installer force-overwrites its skill directories and deletes unshipped entries plus the legacy agentkit directory., Installed skills are rewritten to apply globally in Cursor without an install-time prompt. - **Evidence against:** The write target is the package's own agentsdk namespace rather than an arbitrary project directory., The installer has an environment-variable opt-out and only runs for consumer package installs., No self-dependency, credential collection, exfiltration, or install-time network request was found in the inspected lifecycle path. ## Affected versions and remediation This report applies to @cursor/july@0.1.100. - Review the evidence and your use of @cursor/july@0.1.100 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.
