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. The npm postinstall hook automatically installs package-owned skills into the user’s Cursor skills directory. At runtime, eligible Slack sessions also install follow-up hooks in their workspace. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-10-09T05:56:24.883Z - **Finished:** 2026-10-09T05:57:11.908Z - **Download time:** 1548 ms - **Static scan time:** 6539 ms - **AI review time:** 38936 ms - **Total time:** 47025 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 npm postinstall hook automatically installs package-owned skills into the user’s Cursor skills directory. At runtime, eligible Slack sessions also install follow-up hooks in their workspace. - **Trigger:** Installing the package with npm triggers the skill copy; running an eligible Slack session triggers workspace hook setup. - **Impact:** These actions modify AI-agent configuration without an install-time prompt, so this is a guarded, package-owned agent setup risk. No separate malicious attack behavior was established. - **Evidence paths:** package.json, dist/internal/install-cursor-skills.js, dist/internal/session-engine.js, dist/channels/slack/nudge-carrier.js - **Review source:** ai\_review - **Reviewed:** 2026-10-09T05:57:11.908Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The install hook copies skills and removes obsolete skill folders under the user’s Cursor skills directory. The session engine writes follow-up carrier files and registers commands for pre-tool and post-tool events. - **Rationale:** The postinstall hook makes package-owned agent skill changes without prompting, which falls under the warning policy for first-party agent setup. The Slack hook behavior is runtime-triggered and guarded, and the inspected source does not establish a malicious chain. - **Files touched:** package.json, dist/internal/install-cursor-skills.js, dist/internal/session-engine.js, dist/channels/slack/nudge-carrier.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 postinstall hook automatically launches the package’s skill installer., The installer copies package skills into the user’s Cursor skills directory and removes obsolete skill folders., During eligible Slack sessions, runtime code writes carrier files and adds commands to Cursor’s pre-tool and post-tool hooks., The Slack hook setup is limited to Slack sessions with a continuation key, an owned workspace, and disabled steering. - **Evidence against:** The Slack hook writer is activated at runtime, not by npm installation, and skips borrowed workspaces or when steering is enabled., Inspected behavior shows package-owned skills and Slack follow-up handling; no credential collection or unrelated network recipient was identified. ## Affected versions and remediation This report applies to @cursor/july@0.2.16. - Review the evidence and your use of @cursor/july@0.2.16 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.

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 L37: * L38: * Node caches `import()` by URL for the life of the process, so a long-lived L39: * `agent-sdk dev` would otherwise keep serving the first load of eval files ``` ### 6.
