Controls Claude Stop behavior and installs agent instructions/hooks without explicit user setup. - **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:** 12.2.0 - **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 dependency silently writes broad AI-agent skills and Claude hook configuration into the consumer repository. It also configures Git hooks. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-23T01:23:08.501Z - **Finished:** 2026-08-23T01:24:56.802Z - **Download time:** 514 ms - **Static scan time:** 1948 ms - **AI review time:** 105838 ms - **Total time:** 108301 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the dependency silently writes broad AI-agent skills and Claude hook configuration into the consumer repository. It also configures Git hooks. - **Trigger:** npm postinstall - **Impact:** Controls Claude Stop behavior and installs agent instructions/hooks without explicit user setup. - **Evidence paths:** package.json, bin/lib/postinstall.mjs, bin/lib/init.mjs, bin/lib/materialize.mjs, registry/hooks/opus-check-on-stop.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-23T01:24:56.802Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic consumer-repository agent and hook materialization - **Attack narrative:** npm invokes postinstall, which calls initProject for a consumer project. That setup materializes package-provided skills into .agents and .claude, writes a Claude Stop hook command into .claude/settings.json, and configures Git hooks. These are unconsented install-time mutations of broad AI-agent control surfaces, even though the installed hook primarily runs package checks. - **Rationale:** The lifecycle hook performs automatic, persistent consumer-repository AI-agent control-surface mutation. This meets the firewall block boundary regardless of the apparent developer-tooling purpose. - **Files touched:** .agents/skills/\*, .claude/skills/\*, .claude/hooks/opus-check-on-stop.mjs, .claude/settings.json, .githooks/\*, .git/config ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall automatically runs consumer setup., Setup materializes files into .agents and .claude skill/control paths., It adds a Claude Stop command hook without user invocation., It configures repository Git hooks during install-time setup. - **Evidence against:** No package-owned credential exfiltration endpoint was found., Dynamic DB import is limited to explicit CLI migration use. ## 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. Public source snippet (untrusted): ```json scripts.postinstall = node ./bin/lib/postinstall.mjs ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review.
