No confirmed credential exfiltration or remote-code-execution chain was found in the install path. - **Trigger:** npm install @fleetbo/svro - **Impact:** Creates/patches project schema, typing, TypeScript, Vite, and package configuration files. - **Evidence paths:** package.json, dist/postinstall.cjs, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-28T05:15:04.955Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall project configuration mutation - **Rationale:** This is a documented but unusually invasive, obfuscated install hook that mutates the host project. Source inspection did not establish a concrete malicious chain, so blocking is not justified. - **Files touched:** package.json, svro.schema.json, src/auto-imports.d.ts, tsconfig.json, jsconfig.json, vite.config.ts, vite.config.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** package.json postinstall executes dist/postinstall.cjs on install., dist/postinstall.cjs runs setup against INIT\_CWD/project cwd., Setup writes schema/type files and patches TypeScript, Vite, and package configuration., Published artifacts are heavily obfuscated, hindering audit. - **Evidence against:** README.md explicitly documents automatic postinstall project setup., Postinstall calls runFullSetup with skipSelfInstall:true., The network token handler is separate from runFullSetup and is not called by the postinstall entrypoint., No source evidence of secret harvesting, remote payload execution, or AI-agent configuration writes. ## 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.
