It installs skills and a Claude Stop hook that can run checks and block agent completion. - **Trigger:** npm postinstall during dependency installation - **Impact:** Unconsented persistence and control over Claude agent behavior and repository hooks. - **Evidence paths:** package.json, bin/lib/postinstall.mjs, bin/lib/materialize.mjs, registry/hooks/opus-check-on-stop.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-03T19:50:14.748Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic consumer-project materialization of agent hooks, skills, and Git hooks - **Attack narrative:** On npm installation, the postinstall script locates the consumer project and runs initialization. That initialization writes agent skills, changes Claude settings to register a Stop command hook, installs Git hook files, changes the Git hooks path, and removes ignore entries for those artifacts. The Stop hook runs package-controlled checks against changed applications and exits with a blocking status when it finds violations. These are automatic changes to foreign AI-agent and repository control surfaces rather than an explicit setup command. - **Rationale:** This is malicious install-hook abuse under the policy because an automatic npm postinstall mutates a consumer’s broad AI-agent control surface and Git hooks. No network theft was needed to establish the concrete unconsented control behavior. - **Files touched:** base.json, opus.json, .agents/skills/\*, .claude/skills/\*, .claude/hooks/opus-check-on-stop.mjs, .claude/settings.json, .githooks/pre-push, .githooks/pre-push.d/\*, .githooks/run-opus-pre-push.mjs, .git/config, .git/info/exclude, AGENTS.md, CLAUDE.md ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest automatically runs a postinstall program., The postinstall identifies the consumer project and invokes project initialization without an explicit user command., Initialization materializes skills and a Stop hook into Claude and agent control directories., It alters the consumer Git hook configuration and removes exclusions for agent artifacts., The installed Claude Stop hook can block an agent turn after running package-controlled checks. - **Evidence against:** No install-time network endpoint or credential exfiltration was found in the inspected lifecycle path., The database and generation subprocesses are invoked only by explicit CLI commands. ## Public findings ### 1.
