A package install can alter Claude, Codex, Copilot/OpenCode, and Pi agent behavior through automatic skill registration. - **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:** 7.0.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Global npm installation automatically registers this package as a skill in four third-party AI-agent control surfaces. This changes which instructions those agents can discover without an explicit setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-26T19:33:03.167Z - **Finished:** 2026-08-26T19:33:53.258Z - **Download time:** 256 ms - **Static scan time:** 433 ms - **AI review time:** 49399 ms - **Total time:** 50091 ms ## Security analysis ### Published attack-surface review - **Summary:** Global npm installation automatically registers this package as a skill in four third-party AI-agent control surfaces. This changes which instructions those agents can discover without an explicit setup command. - **Trigger:** npm global installation, which invokes postinstall. - **Impact:** A package install can alter Claude, Codex, Copilot/OpenCode, and Pi agent behavior through automatic skill registration. - **Evidence paths:** package.json, src/install/postinstall.mjs, src/lib/harness-install.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-26T19:33:53.258Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall symlinks or copies package skills into agent skill directories and creates Surf configuration state. - **Attack narrative:** Installing the package globally invokes its postinstall hook. The hook treats global installation as authorization to create agent skill directories and register package-controlled skills in four separate AI-agent systems. Those agents may then load the package's instructions during later sessions, although the user did not run an explicit registration command. The hook also creates persistent configuration state. This is an unconsented, broad AI-agent control-surface mutation performed by npm lifecycle execution. - **Rationale:** The package's global postinstall mutates several foreign AI-agent skill directories automatically. That concrete lifecycle behavior meets the firewall block boundary even though its search networking appears feature-related. - **Files touched:** package.json, src/install/postinstall.mjs, src/lib/harness-install.mjs, ~/.agents/skills, ~/.claude/skills, ~/.codex/skills, ~/.pi/agent/skills, ~/.config/surf/keys.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest runs a postinstall script automatically., On global installation, the script registers skills across four unrelated AI-agent directories., Registration creates package symlinks or copies under Claude, Codex, Copilot/OpenCode, and Pi skill paths., The lifecycle also creates a persistent Surf configuration file in the user home directory. - **Evidence against:** The postinstall exits without changes for ordinary local installs., Network requests are implemented for the advertised search providers and are not used by the lifecycle installer., The installer preserves existing non-symlink user copies. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts.

Critical: Ai Agent Control Hijack - **Category:** Source - **Confidence:** 90.0% - **Path:** src/lib/harness-install.mjs - **Public source:** [View source]() Source creates an unconsented AI-agent control surface through install-time mutation or a default unauthenticated remote skill channel.
