## Security analysis

### Published attack-surface review

- **Summary:** No attack was identified. The install hook downloads supported browser builds into Puppeteer’s configured cache, and the CLI provides browser management.

- **Trigger:** Package installation runs the postinstall hook; browser management runs when a user invokes the CLI.

- **Impact:** The inspected behavior sets up browsers for Puppeteer automation; no confirmed attack effect was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-14T15:37:06.536Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The hook calls Puppeteer’s browser installer with browser and cache configuration, with a configured skip-download setting that returns before installation.

- **Rationale:** Source inspection ties the postinstall hook to supported browser installation and the CLI to browser management. The inspected entrypoints and configuration reveal no concrete attack behavior.

### Review decision

- **Verdict:** Clean

- **Confidence:** 97.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The manifest’s postinstall hook runs the package’s install script., The install script calls Puppeteer’s browser download routine., The routine invokes the browser installer with a browser, cache directory, and build identifier., The installer returns early when the configured global download-skip setting is enabled., The main module exports the Puppeteer Core API and initializes package configuration., The CLI delegates browser management to a browser-focused command using Puppeteer’s configured cache.
