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. This package exposes a real, user-invoked remote AI-agent extension setup surface, but source inspection found no concrete malicious chain or unconsented postinstall mutation. Treat as a guarded lifecycle risk requiring warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-08-13T08:54:20.783Z - **Finished:** 2026-08-13T08:56:57.556Z - **Download time:** 518 ms - **Static scan time:** 633 ms - **AI review time:** 155611 ms - **Total time:** 156773 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:** An explicit \`avatar sync\` downloads a team AI pack and links it into \`.claude\` agent-extension paths. This is a first-party, user-invoked extension lifecycle surface; no install-time mutation or credential exfiltration was confirmed. - **Trigger:** User runs \`avatar sync\` or initializes a workspace using the CLI. - **Impact:** Remotely maintained pack content can supply Claude Code skills, agents, commands, hooks, workflows, and scripts in the initialized workspace. - **Evidence paths:** package.json, bin/postinstall.js, dist/index.js, src/templates/CLAUDE.md.tpl - **Review source:** ai\_review - **Reviewed:** 2026-08-13T08:56:57.556Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** authenticated remote pack download followed by \`.claude\` symlink mounting - **Rationale:** This package exposes a real, user-invoked remote AI-agent extension setup surface, but source inspection found no concrete malicious chain or unconsented postinstall mutation. Treat as a guarded lifecycle risk requiring warning rather than a block. - **Files touched:** .claude/pack/, .claude/skills/, .claude/agents/, .claude/commands/, .claude/hooks/, .claude/workflows/, .claude/scripts/ - **Network endpoints:** https://qpdbkewtpkkbcrptnlos.supabase.co/functions/v1/get-pack ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** Explicit \`avatar sync\` installs a remotely supplied team pack and mounts it into Claude Code convention paths., The pack can provide skills, agents, commands, hooks, workflows, and scripts, becoming available after the user runs sync. - **Evidence against:** The only postinstall hook imports a welcome-screen module and prints output; it does not fetch, write, or configure agent paths., Remote pack retrieval is user-command initiated and uses a fixed/allowlisted Supabase endpoint with an authorization flow. ## Affected versions and remediation This report applies to @nalvietnam/avatar-cli@3.19.11. - Review the evidence and your use of @nalvietnam/avatar-cli@3.19.11 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.
