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 package automatically installs its own Cursor skills during npm postinstall, and Slack session handling can add local Cursor hooks for follow-up context. These are package-owned agent integrations; the inspected source does not establish a separate active attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-10-09T05:56:07.778Z - **Finished:** 2026-10-09T05:56:58.231Z - **Download time:** 1292 ms - **Static scan time:** 6213 ms - **AI review time:** 42947 ms - **Total time:** 50453 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 package automatically installs its own Cursor skills during npm postinstall, and Slack session handling can add local Cursor hooks for follow-up context. These are package-owned agent integrations; the inspected source does not establish a separate active attack. - **Trigger:** npm package installation triggers skill synchronization; Slack session handling with a continuation key triggers nudge carrier setup. - **Impact:** Package skills become available to Cursor, and Slack follow-up context can be loaded during tool use. A guarded agent extension capability is present, but no confirmed malicious action was identified. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T05:56:58.231Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer synchronizes package skills into the user's Cursor skills namespace. The Slack helper writes local carrier files and registers pre-tool and post-tool commands in the project hooks configuration. - **Rationale:** Source inspection confirms automatic, package-owned Cursor skill setup and a Slack continuation hook integration. These warrant a warning for agent extension lifecycle risk; the reviewed evidence does not establish credential theft, broad foreign configuration mutation, or another concrete attack. - **Files touched:** package.json, scripts/install-cursor-skills.mjs, dist/internal/install-cursor-skills.js, dist/channels/slack/nudge-carrier.js, dist/internal/session-engine.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 runs the package's skill installer automatically., The installer writes shipped skills under the user's Cursor skills directory, replacing package-owned copies., The Slack nudge helper writes carrier files and adds pre-tool and post-tool hooks to the project Cursor configuration when a continuation key is present., The Slack channel is an explicit package feature, and the helper is invoked by session handling. - **Evidence against:** The inspected install behavior is limited to the package's own Cursor skills namespace; no unrelated destination or credential transfer was found in the cited install paths., The Slack hook is tied to Slack continuation handling and its local carrier files; these inspected paths show no network exfiltration or remote code loading. ## Affected versions and remediation This report applies to @cursor/july@0.2.12. - Review the evidence and your use of @cursor/july@0.2.12 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.
