Review MERN Code Quality
MERN projects can hide security, testing, and architecture problems across several layers. This skill guides Claude, Codex, and Claude Code through structured reviews with actionable findings.
Copy this request to your Agent. It includes the canonical Skill page and manifest.
Review the Skillstore skill "code-reviewer" from https://skillstore.io/skills/9tykeshav-code-reviewer.md and its manifest at https://skillstore.io/api/skills/9tykeshav-code-reviewer/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.Your Agent should still show its plan and request any confirmation required by the security policy.
Use these links when an AI agent, crawler, or script needs clean context instead of reading the full page.
Using "code-reviewer". Review my Express and React changes before merge.
Expected outcome:
Using "code-reviewer". Audit this MERN app for security issues.
Expected outcome:
Using "code-reviewer". Check project health before a release.
Expected outcome:
The high static score is driven by markdown examples, checklists, and reference snippets for defensive MERN code review. I found no prompt injection, data exfiltration intent, destructive behavior, or executable malicious payload in the reviewed skill content.

Review changed React, Express, MongoDB, and Node.js files before merging a feature branch.
Check a MERN codebase for injection, authentication, secrets, CORS, and XSS risks.
Identify build blockers, missing tests, oversized files, and architecture risks in an existing project.
Review this MERN project for build health, security, maintainability, performance, testing, and architecture issues. Start with the project health checks.
Review the current pull request using the code-reviewer skill. Focus on changed files, but include nearby context when it affects correctness or security.
Perform a security-focused MERN review. Prioritize NoSQL injection, XSS, JWT handling, secrets, CORS, rate limiting, and unsafe command execution.
Review this MERN codebase for architectural risk, oversized modules, duplicated logic, unclear boundaries, weak tests, and performance bottlenecks. Provide prioritized fixes.
