It also installs a bundled or remotely downloaded native application into the user's Applications directory. - **Trigger:** npm installation, through the postinstall lifecycle hook. - **Impact:** Affected agents can receive a package-authored default prompt without an explicit setup command; Intel installs execute an unverified downloaded application bundle. - **Evidence paths:** package.json, scripts/npm-install.js, skills/agent-notify/agents/openai.yaml - **Review source:** ai\_review - **Reviewed:** 2026-09-04T02:53:35.010Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall copies an implicitly invokable skill into multiple agent directories and installs a native app. - **Attack narrative:** During npm installation, the postinstall script copies a package-provided skill into global directories for multiple unrelated AI-agent products. The skill allows implicit invocation and injects a default prompt. The same hook replaces an application under the user's Applications directory; for Intel systems it downloads a release archive selected by an environment-controlled tag, extracts it, and installs it without source verification. This is unconsented install-time mutation of broad AI-agent control surfaces. - **Rationale:** The automatic postinstall hook mutates several foreign, user-wide agent skill directories and enables implicit package-authored behavior. The remote native-app installation further increases the install-time supply-chain attack surface. - **Files touched:** package.json, scripts/npm-install.js, skills/agent-notify, ~/.agents/skills/agent-notify, ~/.codex/skills/agent-notify, ~/.claude/skills/agent-notify, ~/.cursor/skills/agent-notify, ~/Applications/AgentNotify.app - **Network endpoints:** github.com ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The postinstall lifecycle script runs automatically on installation., It copies a package-supplied skill into four different user-wide AI-agent skill directories., The installed skill permits implicit invocation and supplies a default instruction to notify the user., On Intel systems it downloads and installs an unverified release archive, with a release tag controllable through an environment variable. - **Evidence against:** No source-level credential harvesting or secret exfiltration was found., The command wrapper only launches the installed application with user-provided arguments., No runtime dependency on this package's own name is declared. ## Public findings ### 1.
