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. Package installation can update Cursor skills without an interactive prompt, and local Slack sessions can add workspace hooks. These are package-owned agent integrations; the inspected code does not establish a concrete attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-09T05:56:05.157Z - **Finished:** 2026-10-09T05:56:58.248Z - **Download time:** 1770 ms - **Static scan time:** 8366 ms - **AI review time:** 42954 ms - **Total time:** 53091 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:** Package installation can update Cursor skills without an interactive prompt, and local Slack sessions can add workspace hooks. These are package-owned agent integrations; the inspected code does not establish a concrete attack. - **Trigger:** npm installation, or a local Slack session with a continuation key when the session engine materializes its carrier. - **Impact:** The package can update agent instructions during installation and configure a Slack follow-up hook for an eligible workspace; no evidence shows credential theft or unrelated payload execution. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T05:56:58.248Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall hook copies the package's shipped skills into the Cursor skills directory. Slack carrier setup writes workspace files and adds hooks that run the carrier at tool boundaries. - **Rationale:** Source confirms an unprompted postinstall copy/update of package-owned Cursor skills and a guarded Slack workspace-hook setup. These integrations justify a warning, but the reviewed code does not show a concrete malicious chain or credential exfiltration. - **Files touched:** package.json, dist/internal/install-cursor-skills.js, dist/channels/slack/nudge-carrier.js, dist/internal/session-engine.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The postinstall hook runs a package-owned skill installer automatically., The installer copies shipped skills into the user's Cursor skills directory and can overwrite or remove entries there; install is skipped only with an opt-out variable., The Slack runtime writes a carrier and pointers into the workspace and adds pre-tool and post-tool hooks when a local Slack session has a continuation key., The carrier setup is limited to Slack sessions and skipped for borrowed workspaces or when steering is enabled. - **Evidence against:** The installer targets this package's own skills under the vendor's Cursor skills directory, rather than modifying arbitrary agent configuration., The Slack hook supports delivery of queued Slack follow-ups at tool boundaries; no credential transmission or unrelated network behavior was identified in the inspected path. ## Affected versions and remediation This report applies to @cursor/july@0.2.13. - Review the evidence and your use of @cursor/july@0.2.13 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 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.
