Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 4.3.2 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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. Static inspection supports a warning for explicit agent skill installation and updates under the supplied policy. The observed activation and overwrite guards do not support a malicious publish block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-01T14:23:45.259Z - **Finished:** 2026-10-01T14:27:54.226Z - **Download time:** 763 ms - **Static scan time:** 7084 ms - **AI review time:** 241118 ms - **Total time:** 248967 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:** A downloadable helper can install and update skills across configured AI agent directories. This explicit command capability warrants a warning under the supplied agent policy; no confirmed malicious attack was established. - **Trigger:** A user or agent explicitly runs the downloaded helper's install or update command. - **Impact:** Downloaded skills can change subsequent agent behavior in the selected project or home scope. Existing unmanaged directories receive an overwrite guard. - **Evidence paths:** dist/index.js, dist/index.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-01T14:27:54.226Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The helper reads saved backend, client and scope preferences, downloads skill archives, and copies or links their contents into agent skill directories. Updates occur on command rather than through an observed background updater. - **Rationale:** Static inspection supports a warning for explicit agent skill installation and updates under the supplied policy. The observed activation and overwrite guards do not support a malicious publish block. - **Files touched:** .agents/skills, .claude/skills, .windsurf/skills ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** dist/index.js serves a downloadable agent skill bundle containing an executable helper., The bundled helper explicitly installs or updates downloaded skills by copying or linking them into configured agent directories., dist/index.cjs lists agent destinations including .agents/skills, .claude/skills and .windsurf/skills., The helper dispatches explicit commands and skips existing directories without its management marker, limiting automatic overwrite behavior., package.json invokes a postinstall script whose inspected setup operation runs the package's Python setup script. - **Evidence against:** No inspected source establishes covert credential theft or install-time agent configuration mutation., The skill helper requires explicit invocation; its default command displays help rather than installing skills. ## Affected versions and remediation This report applies to @exulu/backend@4.3.2. - Review the evidence and your use of @exulu/backend@4.3.2 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.
