Unconsented persistence and behavior changes across installed AI-agent platforms and a detected project. - **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:** 4.0.13 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. On npm postinstall, the package mutates broad user-level AI-agent control surfaces without an explicit command. It installs active skills/agents across multiple unrelated IDEs and changes Claude settings. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T21:34:03.343Z - **Finished:** 2026-08-05T21:34:40.766Z - **Download time:** 760 ms - **Static scan time:** 5995 ms - **AI review time:** 30668 ms - **Total time:** 37423 ms ## Security analysis ### Published attack-surface review - **Summary:** On npm postinstall, the package mutates broad user-level AI-agent control surfaces without an explicit command. It installs active skills/agents across multiple unrelated IDEs and changes Claude settings. - **Trigger:** npm installation - **Impact:** Unconsented persistence and behavior changes across installed AI-agent platforms and a detected project. - **Evidence paths:** package.json, scripts/install-skills.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-05T21:34:40.766Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall fan-out of AI-agent skills, agents, settings, and auto-upgrade - **Attack narrative:** Installing the package runs a lifecycle script that creates or modifies user-global agent-extension directories for all supported platforms, including Codex, Claude, Cursor, and Trae, rather than only a user-selected platform. It also installs Claude agent files, sets a Claude output style, and can launch an automatic project upgrade based on the install cwd. - **Rationale:** The concrete postinstall fan-out writes behavior-bearing assets into foreign/broad AI-agent control surfaces without explicit user invocation. This meets the install-control-surface block boundary despite no observed exfiltration. - **Files touched:** scripts/install-skills.mjs, ~/.claude/skills, ~/.claude/agents, ~/.claude/settings.json, ~/.codex/skills, ~/.cursor/skills, ~/.trae/skills, \/.peaks ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs scripts/install-skills.mjs as postinstall., install-skills.mjs automatically fans out bundled skills to all configured IDE profiles., The postinstall writes/symlinks into ~/.claude, ~/.codex, ~/.cursor, ~/.trae and other agent directories., It installs bundled agent files and auto-registers peaks-skill-swarm in ~/.claude/settings.json., It may invoke \`peaks upgrade --to 2.0 --auto\` against a detected cwd project during postinstall. - **Evidence against:** No install-time network endpoint or credential exfiltration was found., The installer includes path/symlink safety checks and opt-out environment variables. ## Public findings ### 1.
