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:** 0.8.8 - **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 source shows an explicit, opt-in agent hook installer rather than an automatic lifecycle mutation. Its persistent agent configuration and telemetry behavior fit a guarded capability warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-27T08:38:04.144Z - **Finished:** 2026-09-27T08:39:10.141Z - **Download time:** 780 ms - **Static scan time:** 4973 ms - **AI review time:** 60242 ms - **Total time:** 65997 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:** No unconsented install-time attack was identified. An explicit telemetry setup command can add a Claude Code hook that later reports skill-invocation metadata when telemetry is enabled. - **Trigger:** The user runs the telemetry hook installation command and enables telemetry; Claude Code then invokes the installed hook. - **Impact:** This is a guarded agent-configuration capability and can transmit skill names, session identifiers, duration, and platform after opt-in; no confirmed covert attack surface was established. - **Evidence paths:** dist/cli.js, templates/skill-telemetry.sh - **Review source:** ai\_review - **Reviewed:** 2026-09-27T08:39:10.141Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI writes hook settings and copies a shell script. The script gates on local configuration, builds an anonymous invocation record, and posts it to the selected endpoint. - **Rationale:** The source shows an explicit, opt-in agent hook installer rather than an automatic lifecycle mutation. Its persistent agent configuration and telemetry behavior fit a guarded capability warning. - **Files touched:** ~/.claude/settings.json, ~/.skillsmith/hooks/skill-telemetry.sh, ~/.skillsmith/config.json - **Network endpoints:** https://vrcnzpmndtroqxxoqkzy.supabase.co/functions/v1/events ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The package exposes a CLI entry point and has no npm install lifecycle hook., An explicit telemetry command can install a Claude Code Skill hook into user or project settings., The installer copies its telemetry script and writes the resulting hook settings., The hook exits unless local telemetry is enabled and sends a limited invocation payload to its configured endpoint. - **Evidence against:** The telemetry hook can persist as an AI-agent configuration change after an explicit user command., The install command permits overriding the telemetry endpoint. ## Affected versions and remediation This report applies to @skillsmith/cli@0.8.8. - Review the evidence and your use of @skillsmith/cli@0.8.8 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.
