This is automatic for npm installs on Linux/macOS unless the user sets an opt-out variable. - **Trigger:** npm install, including npx installation, without DEMOVID\_SKIP\_PLANNOTATOR set - **Impact:** The remote host can run arbitrary commands as the installing user and install or alter software. - **Evidence paths:** package.json, scripts/postinstall.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-04T02:59:26.627Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote script download, temporary-file staging, and bash execution - **Attack narrative:** The postinstall hook fetches a live installer from plannotator.ai, stores it in a temporary install.sh, then launches bash with that file. The response is neither pinned nor integrity-checked, so a compromised endpoint or changed installer gains code execution during dependency installation. The package comments acknowledge the upstream installer can modify AI-agent configuration in its default mode, but this package cannot verify the claimed --minimal behavior. - **Rationale:** Automatic execution of an unverified, remotely supplied shell payload is a concrete install-time remote-code-execution chain. Runtime API and media-tool execution do not mitigate that install-time behavior. - **Files touched:** scripts/postinstall.mjs - **Network endpoints:** https://plannotator.ai/install.sh ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall automatically., scripts/postinstall.mjs fetches https://plannotator.ai/install.sh., It writes the unverified response to a temp install.sh and spawns bash on it., The install is enabled by default; DEMOVID\_SKIP\_PLANNOTATOR is only an opt-out., No hash, signature, or pinned artifact verification protects the downloaded script. - **Evidence against:** Other network calls in dist/openai/\* are runtime OpenAI API features using OPENAI\_API\_KEY., dist/exec.js uses execFile with argument arrays rather than a shell. ## Public findings ### 1.
