It also installs or replaces a native application in the user's Applications directory and may download a release archive. - **Trigger:** npm postinstall during package installation - **Impact:** An install can introduce implicitly invokable agent instructions across Codex, Claude, Cursor, and generic agent skill surfaces without user setup consent. - **Evidence paths:** package.json, scripts/npm-install.js, skills/agent-notify/agents/openai.yaml - **Review source:** ai\_review - **Reviewed:** 2026-09-04T16:28:36.860Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic global AI-agent skill installation and native app deployment - **Attack narrative:** When npm installs this package, its postinstall script deploys a native application and copies the packaged skill into four global AI-agent skill roots. The Codex skill allows implicit invocation, so the install changes multiple agent control surfaces without a separate user-directed setup action. Intel installations download and unpack a release archive before replacing the installed application. - **Rationale:** The automatic postinstall mutation of broad, foreign AI-agent control surfaces is a concrete malicious install-hook abuse under the policy. The absence of visible credential theft does not neutralize that unconsented lifecycle behavior. - **Files touched:** scripts/npm-install.js, skills/agent-notify, prebuilt/AgentNotify.app, $HOME/Applications/AgentNotify.app, $HOME/.agents/skills/agent-notify, $HOME/.codex/skills/agent-notify, $HOME/.claude/skills/agent-notify, $HOME/.cursor/skills/agent-notify - **Network endpoints:** https://github.com/sally1913105/AgentNotify/releases/download/${releaseTag}/${asset} ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package automatically runs its installer through a postinstall lifecycle hook., The installer copies a skill into four global agent-control directories under the user's home directory without an explicit setup command., The installer replaces a home-directory app bundle and downloads an architecture-specific release archive before copying it into place., The installed Codex skill permits implicit invocation and supplies a default prompt. - **Evidence against:** No source code reads environment secrets, credentials, or arbitrary user files., The only source-visible network target is the package's GitHub release URL. ## Public findings ### 1.
