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. On installation, the package installs its own Cursor skills as global rules. This is an automatic first-party agent-extension setup, not a confirmed payload or data-theft path. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-10T00:32:08.571Z - **Finished:** 2026-09-10T00:33:18.459Z - **Download time:** 1274 ms - **Static scan time:** 10897 ms - **AI review time:** 57715 ms - **Total time:** 69888 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:** On installation, the package installs its own Cursor skills as global rules. This is an automatic first-party agent-extension setup, not a confirmed payload or data-theft path. - **Trigger:** Installing @cursor/july through npm or npx. - **Impact:** Future Cursor sessions may load package-provided instructions globally; the installer can overwrite its namespace and remove its legacy namespace. - **Evidence paths:** package.json, scripts/install-cursor-skills.mjs, dist/internal/install-cursor-skills.js - **Review source:** ai\_review - **Reviewed:** 2026-09-10T00:33:18.459Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall copies shipped skills into Cursor’s global skills directory and enables always-apply behavior. - **Rationale:** This is an automatic global AI-agent extension mutation and should be warned on. The source does not establish the broader or stealthy behavior required for a publish block. - **Files touched:** scripts/install-cursor-skills.mjs, dist/internal/install-cursor-skills.js, ~/.cursor/skills/agentsdk/\/, ~/.cursor/skills/agentkit/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The postinstall hook automatically launches a package script during npm installation., The launched script imports the skill installer and runs it without an interactive consent step., The installer copies shipped content into Cursor’s global skills directory and marks it always applicable, so it affects future Cursor sessions. - **Evidence against:** The installation path is limited to this package’s agentsdk namespace and has an opt-out environment variable., The reviewed lifecycle code shows no network access, credential collection, self-dependency, or remote payload execution. ## Affected versions and remediation This report applies to @cursor/july@0.1.105. - Review the evidence and your use of @cursor/july@0.1.105 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. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4.

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.

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.
