Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 2.6.0 - **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. Source establishes automatic package-owned agent extension setup, which the supplied policy classifies as warning-worthy. The inspected behavior does not establish a block-eligible malicious chain or broad agent configuration hijack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-01T03:23:42.015Z - **Finished:** 2026-10-01T03:24:46.072Z - **Download time:** 1553 ms - **Static scan time:** 178 ms - **AI review time:** 62324 ms - **Total time:** 64057 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 Claude skills. This creates an agent extension lifecycle risk, but no confirmed malicious attack was established. - **Trigger:** Installing or reinstalling the package through npm. - **Impact:** Installation adds or replaces package-owned instructions available to Claude, potentially changing later agent behavior. - **Evidence paths:** package.json, bin/install.js - **Review source:** ai\_review - **Reviewed:** 2026-10-01T03:24:46.072Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer copies bundled skills and supporting files into global or project-local .claude/skills directories without a separate consent prompt. - **Rationale:** Source establishes automatic package-owned agent extension setup, which the supplied policy classifies as warning-worthy. The inspected behavior does not establish a block-eligible malicious chain or broad agent configuration hijack. - **Files touched:** .claude/skills, .gitignore ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json automatically runs bin/install.js after npm installation., The installer targets global or project-local .claude/skills directories., The installer copies its bundled skills, shared references, workflows, and guidance without a separate consent prompt. - **Evidence against:** Writes are directed to this package’s skill payload rather than broad agent settings., The flagged test configuration write occurs in a temporary test repository; tests are excluded from the installed workflow payload., No concrete credential theft, remote payload execution, or malicious control hijack was established. ## Affected versions and remediation This report applies to @houseofwolvesllc/claude-scrum-skill@2.6.0. - Review the evidence and your use of @houseofwolvesllc/claude-scrum-skill@2.6.0 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.
