A dependency silently adds persistent package-authored guidance that participating coding agents may follow. - **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:** 0.0.6 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package can mutate a consumer project's Kiro or Cursor instruction directories. This alters a foreign AI-agent control surface without an explicit setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-03T14:11:19.586Z - **Finished:** 2026-08-03T14:11:50.133Z - **Download time:** 1035 ms - **Static scan time:** 983 ms - **AI review time:** 28528 ms - **Total time:** 30547 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package can mutate a consumer project's Kiro or Cursor instruction directories. This alters a foreign AI-agent control surface without an explicit setup command. - **Trigger:** npm installation runs the postinstall lifecycle hook. - **Impact:** A dependency silently adds persistent package-authored guidance that participating coding agents may follow. - **Evidence paths:** package.json, scripts/postinstall.js, docs/implement-tantuui-token.md, dist/postcss.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T14:11:50.133Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall creation or replacement of AI assistant instruction files - **Attack narrative:** On npm install, the lifecycle script locates the consuming project and copies a package-controlled AI instruction document into existing Kiro or Cursor control directories, falling back to docs. It also replaces a prior file bearing its marker. This is unconsented install-time mutation of foreign AI-agent configuration, so the package can influence future agent actions in the consumer repository. - **Rationale:** Source inspection confirms an install-time write to \`.kiro/steering\` and \`.cursor/rules\`; this meets the policy's concrete foreign AI-agent control-surface mutation boundary. No separate exfiltration or remote payload chain was found. - **Files touched:** scripts/postinstall.js, docs/implement-tantuui-token.md, .kiro/steering/implement-tantuui-token.md, .cursor/rules/implement-tantuui-token.md, docs/implement-tantuui-token.md ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs \`node scripts/postinstall.js\` on install., scripts/postinstall.js automatically writes an AI-context document into \`.kiro/steering\` or \`.cursor/rules\` in the consumer project., The write occurs during dependency installation, without an explicit user command or consent., docs/implement-tantuui-token.md identifies itself as AI-tool guidance and directs coding-assistant behavior. - **Evidence against:** No network, credential harvesting, shell execution, or payload download was found in the inspected lifecycle script., The injected document contains package usage guidance rather than credential or destructive instructions., dist/postcss.js file reads support its PostCSS utility loader; its bundled dynamic-function pattern is dependency code. ## Public findings ### 1.
