Use this skill when you need to diagnose and fix React 19 performance issues (render churn, slow updates, Suspense/Transitions, memoization, profiling, and React Compiler).

Write clean, behavior-focused unit/integration tests that remain trustworthy when code is written or modified by agents (prevents “test weakening”, enforces invariants, and adds CI guardrails).

Use this skill when you are creating or updating Agent Skills in your project (structure, YAML frontmatter, naming, and progressive disclosure).

Use this skill when designing or refactoring boundaries, responsibilities, and change drivers using practical software architecture “hard parts” thinking + SRP.

Use this skill when you need a Bun runbook (dev, build, lint, typecheck, tests, migrations, and verification steps).

Use this skill when you need a thorough code hygiene pass (dead code, lint escapes, consistency, formatting drift, and subtle smells) on touched files.

Use this skill when you need a senior-level review of a PR/diff for security, correctness, performance, and maintainability (TypeScript + React 19 + Next.js 16).

Use this skill when you want fast, actionable critique of a file/snippet/approach (not necessarily a PR), focused on security, correctness, performance, and DX.

Use this skill when writing or optimizing Drizzle ORM queries for performance (relations, transactions, batching, prepared statements, indexes, and avoiding N+1).

Use this skill when you write or review any Drizzle DB read/write and must enforce strict `workspace_id` tenant isolation.

Use this skill when you add or change locale-aware UI (en/de) with next-intl: routing, UI copy, and date/number/currency formatting.

Use this skill when optimizing Next.js 16 routes/Server Components/Server Actions for Vercel latency and cost (invocations + duration) using tenant-safe caching and streaming.

Use this skill when you implement or review Next.js Server Actions or server-side data fetching that touches tenant/workspace data (auth provider + ORM + i18n, tenant-safe).

Use this skill when you work on invoices or PDFs draft→finalize, immutable invoice snapshots, numbering, and PDF rendering/export.

Use this skill when you need to triage, draft, or improve a GitHub issue with strong repro steps and acceptance criteria; use runSubagent to gather evidence and pre-fill the issue.

Use this skill when you review or write React components (.tsx/.jsx) and need React 19 best practices (especially eliminating unnecessary useEffect).

Use this skill when adding or reviewing code that touches auth, tenancy, input validation, webhooks, secrets, caching, or user-provided content (strict security rules).

Use this skill when building dashboard UI with Tailwind v4 + shadcn/ui and you want consistent layouts, components, and patterns.

Use this skill when writing, reviewing, or refactoring TypeScript code for type safety, idiomatic patterns, and modern best practices.

Use this skill when designing and implementing new UI (pages, forms, lists, tables, dialogs, empty states) with shadcn/ui + Tailwind v4.

Use this skill when validating untrusted inputs with Zod v4 (Server Actions, Route Handlers, forms), formatting errors, or migrating Zod v3 → v4.
