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:** 0.1.2 - **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. The postinstall hook makes first-party skills and agent rules available automatically in consumer projects, creating a real agent-configuration lifecycle risk. Because the changes are package-owned setup with an uninstall path, classify it as suspicious and warn rather than block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-11T16:56:30.206Z - **Finished:** 2026-10-11T16:56:55.393Z - **Download time:** 1030 ms - **Static scan time:** 29 ms - **AI review time:** 24127 ms - **Total time:** 25187 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 postinstall hook automatically adds this package's skills and rules to the consumer project's agent configuration. - **Trigger:** Installing the package with npm runs its postinstall hook. - **Impact:** The project receives agent instructions and skills that may affect later agent sessions; the package provides an uninstall script to remove its managed changes. - **Evidence paths:** package.json, scripts/install.mjs, scripts/uninstall.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-11T16:56:55.393Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer copies skills into .claude/skills and writes a managed rules block into AGENTS.md or CLAUDE.md without a separate consent prompt. - **Rationale:** The postinstall hook makes first-party skills and agent rules available automatically in consumer projects, creating a real agent-configuration lifecycle risk. Because the changes are package-owned setup with an uninstall path, classify it as suspicious and warn rather than block. - **Files touched:** .claude/skills/, AGENTS.md, CLAUDE.md, .gitignore, .claude/softure-skills.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json runs the installer automatically through a postinstall hook., The installer targets the consumer project's .claude directory and chooses AGENTS.md or CLAUDE.md for its rules block., The installer writes the package's rules into that file without a consent check; the write is skipped only in dry-run mode., The uninstall script removes installed skills and strips its managed blocks. - **Evidence against:** The setup installs this package's own skills and rules, matching its stated purpose; policy treats this first-party extension setup as warning-level risk., The inspected installer and uninstaller show no network transfer or credential collection. ## Affected versions and remediation This report applies to @softure-ai/skills@0.1.2. - Review the evidence and your use of @softure-ai/skills@0.1.2 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.
