Consumer project agent behavior and future dependency lifecycle execution are modified. - **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:** 1.5.123 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Unconsented postinstall changes consumer package-manager settings and writes AI-agent control surfaces. This makes the package's rules and skills automatically active in the host project. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-12T02:58:36.448Z - **Finished:** 2026-08-12T03:00:48.935Z - **Download time:** 767 ms - **Static scan time:** 98 ms - **AI review time:** 131621 ms - **Total time:** 132487 ms ## Security analysis ### Published attack-surface review - **Summary:** Unconsented postinstall changes consumer package-manager settings and writes AI-agent control surfaces. This makes the package's rules and skills automatically active in the host project. - **Trigger:** npm/pnpm installation - **Impact:** Consumer project agent behavior and future dependency lifecycle execution are modified. - **Evidence paths:** package.json, postinstall.js, merge.js - **Review source:** ai\_review - **Reviewed:** 2026-08-12T03:00:48.935Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall-driven AI-agent configuration injection - **Attack narrative:** On installation, the package appends settings that enable dependency pre/post scripts and disable pnpm's side-effects cache, then launches its merge command in the consumer project. That command writes AGENTS.md, CLAUDE.md, Copilot instruction files, and copied Claude skills, creating an unconsented broad AI-agent control surface. - **Rationale:** The lifecycle hook performs broad, persistent AI-agent configuration mutation in a consuming project and changes package-manager lifecycle behavior. This meets the install-time foreign/broad control-surface block boundary. - **Files touched:** .npmrc, AGENTS.md, CLAUDE.md, AGENTS.private.md, .github/copilot-instructions.md, .github/instructions/\*.instructions.md, .github/PULL\_REQUEST\_TEMPLATE.md, .claude/skills/\* ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** npm postinstall runs automatically., It modifies consumer .npmrc to force dependency lifecycle scripts and disable cache., Install then writes Copilot, Claude, and AGENTS control files into the consumer project., It also installs package skills into the consumer .claude directory. - **Evidence against:** No network, credential harvesting, or remote payload execution found. ## Public findings ### 1.
