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:** 2.10.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM treats this as warn-only first-party agent extension lifecycle risk. The package performs first-party Claude skill setup during npm postinstall and runs a catalog sync helper. This is install-time AI-agent extension lifecycle risk, but source inspection did not confirm malicious hijack, exfiltration, or destructive behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 86.0% - **Started:** 2026-07-06T04:17:19.604Z - **Finished:** 2026-07-06T04:18:12.280Z - **Download time:** 260 ms - **Static scan time:** 47 ms - **AI review time:** 52368 ms - **Total time:** 52676 ms ## Security analysis ### Published attack-surface review - **Summary:** The package performs first-party Claude skill setup during npm postinstall and runs a catalog sync helper. This is install-time AI-agent extension lifecycle risk, but source inspection did not confirm malicious hijack, exfiltration, or destructive behavior. - **Trigger:** npm install postinstall; later explicit hyper-animator/skill helper commands - **Impact:** Claude Code may later load the installed hyper-animator skill; install may populate HyperFrames catalog cache under the skill directory. - **Evidence paths:** package.json, install.js, skills/hyper-animator/SKILL.md, skills/hyper-animator/scripts/sync-catalog.py, skills/hyper-animator/scripts/minimax-gen.py, skills/hyper-animator/scripts/tts-gen.py - **Review source:** ai\_review - **Reviewed:** 2026-07-06T04:18:12.280Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall copies Claude skill files and invokes Python catalog sync - **Rationale:** Because postinstall mutates an AI-agent skill surface and executes a helper, this should warn, but the mutation is first-party/package-scoped and no confirmed exfiltration, destructive action, or stealth remote payload was found. Treat as agent extension lifecycle risk rather than publish-block malware. - **Files touched:** ~/.claude/skills/hyper-animator, ~/.claude/skills/hyper-animator/.env, ~/.claude/skills/hyper-animator/SKILL.md, ~/.claude/skills/hyper-animator/references/source-cache/, ~/.claude/skills/hyper-animator/references/hyperframes-catalog-map.json - **Network endpoints:** https://platform.minimaxi.com, api.minimaxi.com, api.minimax.io, https://cdn.jsdelivr.net/npm/gsap@3.14.2/dist/gsap.min.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for:** package.json defines postinstall: node install.js., install.js postinstall copies bundled files into ~/.claude/skills/hyper-animator., install.js creates/updates ~/.claude/skills/hyper-animator/.env placeholders for MiniMax keys., install.js executes python3 ~/.claude/skills/hyper-animator/scripts/sync-catalog.py during install., sync-catalog.py shells out to hyperframes add/catalog and writes source-cache/catalog files under the installed skill. - **Evidence against:** Mutation is scoped to package-owned ~/.claude/skills/hyper-animator, matching the advertised Claude Code skill purpose., No code found harvesting existing secrets; .env loader only reads package-specific MiniMax vars for user-invoked API helpers., No destructive behavior, persistence outside the skill directory, reviewer prompt injection, or hidden remote payload execution found., MiniMax network calls in minimax-gen.py and tts-gen.py are user-invoked helpers for audio/TTS generation. ## Public findings ### 1.
