react-perf-audit

Audit React and Next.js codebases against roughly 50 concrete performance rules spanning re-render hygiene, bundle size, data-fetching waterfalls, images and fonts, list virtualization, and effect discipline, then apply the safest high-impact fixes and prove the win with before/after bundle numbers. Use when someone says "audit React performance", "why is my Next.js app slow", "reduce bundle size", "fix re-renders", "app feels laggy", "optimize my components", "check for waterfalls", "React best practices pass", "lighthouse score is bad", "hydration is slow", or before a launch when a performance sweep of routes and components is needed.

unit-testGenerate comprehensive unit tests with edge cases, error paths, and boundary values. Auto-detects test framework (Vitest, Jest, pytest, go test, flutter_test, RSpec, cargo test, JUnit), scans for untested functions by priority, adopts existing test conventions, generates tests with proper mocks, runs them, and self-heals failures in up to 3 iterations. Measures coverage before and after. Use when you need to add unit tests, increase code coverage, test edge cases, or verify error handling paths.18 installs design-to-codeTurn a design into production-quality frontend code: extract a design system with tokens and components, make layouts responsive across breakpoints, add dark mode with WCAG-compliant theming, then run a UX audit to validate everything. Use when implementing UI from Figma, adding theming, making an app responsive, or overhauling frontend design consistency.17 installs security-reviewSecurity audit and vulnerability assessment for any codebase. Scans for authentication bypasses, missing auth middleware, broken JWT validation (algorithm confusion, weak secrets, missing expiry), OAuth state and PKCE flaws, IDOR and horizontal privilege escalation, vertical privilege escalation via role manipulation, SQL injection, NoSQL injection, XSS (stored, reflected, DOM), command injection, path traversal, SSRF, CSRF, hardcoded secrets and API keys (sk_live_, AKIA, ghp_), .env and credential file exposure, PII leaking in logs and error responses, overfetching sensitive fields, CORS misconfiguration, session fixation, missing secure/httpOnly/sameSite cookie flags, and Firebase/Firestore rule weaknesses. Produces a severity-ranked findings report with exploit scenarios and fix recommendations. Covers OWASP Top 10.15 installs preflightPre-deploy verification gate. Checks git status, build, tests, migrations, secrets, and commit conventions. Reports READY or NOT READY. Read-only, no changes. Trigger words: preflight, pre-deploy check, ready to deploy, deployment checklist.11 installs cleanup-sprintDeep codebase cleanup — kills dead code, fixes all lint/format warnings, removes orphaned files, cleans stale TODOs, strips security hazards, tightens TypeScript strict mode, and organizes imports. Triggers on: clean up, dead code, unused imports, lint, technical debt cleanup, spring cleaning, tidy up the codebase, remove dead code, code hygiene, declutter.10 installs skillifyCreate a reusable, self-healing, self-evolving global skill — either from the current conversation context OR from a plain-language description of a workflow. Triggers on: 'turn this into a skill', 'make a skill from this', 'skillify this', 'capture this as a skill', 'save this workflow as a skill', 'create a skill for this', 'make this repeatable', 'skill this up', 'build me a skill that does X', 'I want a skill for Y', or any time a workflow just played out and the user wants to preserve it. Invoke even if the user only hints at wanting to reuse what just happened.7 installs

What does the react-perf-audit skill do?

How do I install the react-perf-audit skill?

Run `npx @skills-hub-ai/cli install react-perf-audit` from your terminal.
