## Security analysis

### Published attack-surface review

- **Summary:** No attack was identified. The install hook invokes Playwright's Chromium installer, and the inspected network fetchers support caller-invoked documentation retrieval.

- **Trigger:** Installation invokes the declared postinstall hook; documentation network access occurs when fetch operations are called.

- **Impact:** The inspected behavior supports browser setup and documentation ingestion; no malicious package behavior was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-10T02:27:09.333Z

### AI review details

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

- **Mechanism:** The postinstall command runs Playwright's browser installer. The GitHub fetcher clones a supplied repository and sparse-checks out supplied paths; Context7 fetching is limited to configured plugin topics.

- **Rationale:** The flagged lifecycle hook performs Playwright Chromium setup. The inspected network code implements documentation retrieval using supplied sources, with no concrete attack behavior established.

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

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

### Review decision

- **Verdict:** Clean

- **Confidence:** 95.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The postinstall hook installs Chromium through Playwright; it does not mutate consumer approval settings., GitHub fetching is an exported, caller-invoked documentation feature that uses the supplied repository and documentation paths., Context7 fetching is a feature-specific function that returns without fetching when the plugin has no configured topic list., The package entrypoint exports knowledge-engine and documentation-fetching functionality.

Public source snippet (untrusted):

```javascript
matchType = previous_version_dangerous_delta
matchedPackage = @devflow-tools/knowledge-engine@0.18.20
matchedIdentity = npm:[redacted]:0.18.20
similarity = 0.767
