Unconsented installation of third-party agent instructions/capabilities that other agents may discover and load. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 2026.7.27-1 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. npm postinstall automatically installs third-party Lark CLI skills into the user's global ~/.agents/skills directory. This mutates a broad AI-agent control surface and executes an external npx command without an explicit user command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-07-26T17:57:43.344Z - **Finished:** 2026-07-26T17:58:29.447Z - **Download time:** 2840 ms - **Static scan time:** 2899 ms - **AI review time:** 40362 ms - **Total time:** 46103 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall automatically installs third-party Lark CLI skills into the user's global ~/.agents/skills directory. This mutates a broad AI-agent control surface and executes an external npx command without an explicit user command. - **Trigger:** npm install of kaijibot - **Impact:** Unconsented installation of third-party agent instructions/capabilities that other agents may discover and load. - **Evidence paths:** package.json, scripts/postinstall-bundled-plugins.mjs, README.md - **Review source:** ai\_review - **Reviewed:** 2026-07-26T17:58:29.447Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall-driven global AI-agent skill installation via npx - **Attack narrative:** Installing the package runs its postinstall hook. The hook calls npx to add all larksuite/cli skills globally, writing lark-\* SKILL.md directories under ~/.agents/skills unless a user already set an opt-out variable. This changes a generic agent skill discovery surface outside the package without an explicit setup command. - **Rationale:** Source confirms an unconsented postinstall mutation of a foreign, broad AI-agent control surface. README disclosure and an opt-out do not change that automatic install-time behavior. - **Files touched:** scripts/postinstall-bundled-plugins.mjs, ~/.agents/skills/ ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json postinstall runs scripts/postinstall-bundled-plugins.mjs., Postinstall invokes npx -y skills add larksuite/cli -g --all., It targets ~/.agents/skills, a global agent skill control surface., The action runs automatically unless an opt-out environment variable is preset. - **Evidence against:** README.md discloses the postinstall behavior., The installer verifies only lark-\* skill directories. ## Public findings ### 1.
