Package-authored prompts and configuration become available to Claude, Codex, Cursor, Trae, and other agent environments; matching projects may also be auto-upgraded. - **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:** 4.0.16 - **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 runs an unconsented postinstall that mutates multiple AI-agent control surfaces. It installs package-authored skills, agents, output styles, and defaults into user IDE directories. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-06T14:25:20.116Z - **Finished:** 2026-08-06T14:26:10.688Z - **Download time:** 502 ms - **Static scan time:** 5782 ms - **AI review time:** 44287 ms - **Total time:** 50572 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package runs an unconsented postinstall that mutates multiple AI-agent control surfaces. It installs package-authored skills, agents, output styles, and defaults into user IDE directories. - **Trigger:** npm install / npm i -g peaks-loop - **Impact:** Package-authored prompts and configuration become available to Claude, Codex, Cursor, Trae, and other agent environments; matching projects may also be auto-upgraded. - **Evidence paths:** package.json, scripts/install-skills.mjs, dist/services/skills/hooks-settings-service.js, dist/cli/commands/hooks-commands.js - **Review source:** ai\_review - **Reviewed:** 2026-08-06T14:26:10.688Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall cross-platform AI-agent skill and configuration installation - **Attack narrative:** The npm postinstall runs without an explicit user command. It iterates all supported IDE profiles and installs symlinks/files into their agent skill, agent, and output-style directories; it also auto-registers a Claude output style and can auto-upgrade a detected project. This is broad foreign AI-agent control-surface mutation at install time. - **Rationale:** The lifecycle behavior is concrete and directly mutates broad, third-party AI-agent configuration and prompt-extension locations without consent. Safety checks and lack of observed exfiltration do not remove that install-time control-surface risk. - **Files touched:** scripts/install-skills.mjs, skills/\*\*, agents/\*\*, output-styles/\*\*, ~/.claude/skills, ~/.claude/agents, ~/.claude/output-styles, ~/.claude/settings.json, ~/.codex/skills, ~/.codex/agents, ~/.codex/output-styles, ~/.cursor/skills, ~/.trae/skills ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs scripts/install-skills.mjs as postinstall., scripts/install-skills.mjs automatically links bundled skills across eight IDE platforms., Postinstall writes agents/output styles and ~/.claude/settings.json., It also auto-dispatches \`peaks upgrade --to 2.0 --auto\` when project state matches., dist/services/skills/hooks-settings-service.js can write IDE hook and permission-deny settings. - **Evidence against:** No network or credential-exfiltration path was found in inspected lifecycle code., Writes use managed markers and path/symlink safety checks. ## Public findings ### 1.
