No install-time npm lifecycle execution occurs. After explicit installation, the package-owned Hermes plugin runs a guarded pre\_llm\_call auto-update that fetches the npm registry and invokes npx to replace its own plugin payload. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-15T14:53:39.437Z - **Finished:** 2026-08-15T14:54:24.294Z - **Download time:** 506 ms - **Static scan time:** 890 ms - **AI review time:** 43460 ms - **Total time:** 44857 ms ## Security analysis ### Published attack-surface review - **Summary:** No install-time npm lifecycle execution occurs. After explicit installation, the package-owned Hermes plugin runs a guarded pre\_llm\_call auto-update that fetches the npm registry and invokes npx to replace its own plugin payload. - **Trigger:** Explicit \`lithermes install --yes\`, then an interactive first Hermes turn when a newer version exists. - **Impact:** A future registry version can be installed into the Hermes plugin/config surface without a separate update command. - **Evidence paths:** package.json, assets/lithermes-plugin/plugin.yaml, assets/lithermes-plugin/auto\_update.py, src/lib/install.js, src/lib/updateNotifier.js - **Review source:** ai\_review - **Reviewed:** 2026-08-15T14:54:24.294Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** First-party Hermes plugin setup with guarded automatic npm update. - **Rationale:** Source shows a real first-party agent extension lifecycle with automatic remote package replacement, so it warrants warning under policy. No concrete malicious chain or unconsented npm install hook was found. - **Files touched:** assets/lithermes-plugin/plugin.yaml, assets/lithermes-plugin/auto\_update.py, src/lib/install.js, ~/.hermes/plugins/lithermes, ~/.hermes/config.yaml - **Network endpoints:** https://registry.npmjs.org/lithermes-ai/latest ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** Installed plugin auto-loads lifecycle hooks including pre\_llm\_call., On an interactive first turn, the hook fetches npm latest and runs npx for that exact version., Explicit install copies a first-party plugin and updates Hermes config. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., Auto-update is limited to interactive first turns and has opt-out/recursion guards., Child update environment excludes npm config, proxies, NODE\_OPTIONS, and token-bearing variables. ## Public findings ### 1.
