## Security analysis

### Published attack-surface review

- **Summary:** No attack surface was identified. The install hook sets up the browser dependency, and the inspected network functions retrieve documentation through exported APIs.

- **Trigger:** Package installation runs the postinstall hook; runtime retrieval occurs when a caller invokes the exported fetch functions.

- **Impact:** No malicious or unconsented behavior was established in the inspected source.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-17T08:48:38.133Z

### AI review details

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

- **Mechanism:** The hook runs Playwright's Chromium installer. Runtime fetches retrieve a caller-provided URL or documentation from Context7.

- **Rationale:** Source inspection shows a Playwright browser setup hook and caller-invoked documentation retrieval. The inspected behavior provides no concrete evidence of malicious activity.

- **Files touched:** package.json, dist/index.js, dist/fetcher.js, dist/context7-fetcher.js

### Review decision

- **Verdict:** Clean

- **Confidence:** 91.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The postinstall command installs Chromium through Playwright and tolerates installation failure., The package exports document-fetching APIs that accept a URL, and the fetcher requests that URL., Context7 retrieval constructs requests to the fixed Context7 service for library documentation.
