## Security analysis

### Published attack-surface review

- **Summary:** No attack was identified. The postinstall hook installs the package’s Chromium browser dependency; the network code retrieves documentation from GitHub or Context7 for ingestion.

- **Trigger:** Package installation triggers the Playwright postinstall command; documentation requests occur when the corresponding fetch functions are called.

- **Impact:** No concrete harmful effect was established from the inspected source.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-10T02:27:56.296Z

### AI review details

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

- **Mechanism:** The GitHub fetcher clones a requested repository and reads Markdown under requested paths. The Context7 fetcher sends fixed topic queries to the Context7 API.

- **Rationale:** The inspected lifecycle hook installs Chromium, and the network code retrieves documentation from its named providers for ingestion. The flagged GitHub process execution is tied to a requested repository and documentation paths; no concrete attack behavior was identified.

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

- **Network endpoints:** https://github.com/${repo}.git, https://context7.com/api/v2/context

### Review decision

- **Verdict:** Clean

- **Confidence:** 94.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** package.json runs Playwright’s Chromium installer during postinstall., dist/git-fetcher.js clones a requested GitHub repository and reads Markdown files from requested documentation paths., dist/context7-fetcher.js fetches documentation from context7.com using the requested library ID and fixed topic queries.
