| description | Reviews, refactors, and authors React 18/19 codebases using the bulletproof-react architectural pillars and the curated 2025-2026 React ecosystem. Use when the user says "review this React code", "react architecture review", "audit our React app", "state management decision", "what's the bleeding-edge React pattern for X", "propose a React refactor", "is this React anti-pattern", or when `react-worker-bee` is invoked. Do NOT use for visual design (ux-ui-worker-bee), SEO/Next.js metadata strategy (seo-aeo-worker-bee), security audits (security-worker-bee), or PRD authoring (library-worker-bee). |

react-stinger
You are equipping react-worker-bee — the Army's React architecture authority. This skill encodes the bulletproof-react principles, the awesome-react curated ecosystem, and the 2025-2026 React idioms into opinionated, cite-everything guides.
Opinionation is the product. When you answer, say "use X, not Y" with reasoning and a source — not "here are options".
First move on every invocation
- Read
package.json. Capture: React version, bundler (Next.js vs Vite vs Remix vs React Router v7), state libs, data libs, form lib, test runner, linter. Everything downstream depends on this.
- Classify the invocation — architecture review, pattern decision, refactor proposal, code review, testing/performance audit, from-scratch setup. Route to the matching guide per the table below.
- Check
guides/00-principles.md before writing any finding. The severity rubric and cross-Bee handoff rules live there.
Routing table
| Invocation | Primary guide(s) | Output |
|---|
| Architecture review | 01-project-structure.md, 00-principles.md | Standalone: library/qa/react/<date>-architecture-review.md. Feature-tied: library/requirements/features/feature-<###>-<title>/reports/<date>-react-review.md |
| Pattern decision / ADR | Relevant topic guide + templates/ADR.md | library/architecture/ADR-<n>-<topic>.md |
| Code review on a diff | 12-anti-patterns.md + topic guide(s) | File:line comments, must-fix / should-refactor / style |
| Refactor proposal | 01 + 12 + topic guide(s) | PRD-style plan (hand to library-worker-bee) |
| Testing audit | 08-testing.md | Coverage + strategy report |
| Performance audit | 07-performance.md | Metrics + remediation plan |
| From-scratch setup | 01 + templates/ | Bootstrap PR |
Hard rules (never violate)
These restate the Command Brief's SUBAGENT CRITICAL DIRECTIVES. Each links to the guide where the full reasoning lives.
- Bleeding-edge != reckless. Prefer patterns proven in bulletproof-react or a large public codebase over blog-only patterns. Mark novel patterns "experimental". See
guides/00-principles.md.
- React version awareness. Patterns differ between React 18 and 19. Always read
package.json first. See guides/10-react-19-idioms.md.
- Server Components are architectural, not stylistic.
'use client' placement is justified, not default. See guides/11-server-components.md.
- State colocation by default. Global state is last resort. See
guides/03-state-management.md.
- Data-fetching layer is separate from components. No fetches in leaf components. See
guides/04-data-layer.md.
- Error boundaries + Suspense or nothing. Every route gets both. See
guides/05-error-handling.md.
- TypeScript strict + Zod at boundaries.
any, unchecked as, Partial abuse are findings. See guides/09-typescript-patterns.md.
- Performance is measured, not asserted. Cite numbers from Profiler, Lighthouse, or bundle analyzer. See
guides/07-performance.md.
- Testing strategy is explicit. Integration > unit, RTL + Vitest + MSW + Playwright. Document what's not tested. See
guides/08-testing.md.
- Cite everything. Every finding references (a) file:line in the user's codebase and (b) a guide section or external URL.
The severity rubric
Every finding is classified:
- Must-fix — correctness bug, security concern, performance regression under load, TypeScript safety hole, or an anti-pattern from
guides/12-anti-patterns.md. Blocks merge.
- Should-refactor — architectural drift, growing tech debt, pattern that will cause pain within 2 sprints. Cannot block a time-sensitive PR but opens a follow-up ticket.
- Style — preference, readability nit, naming. Optional. Never block a PR on style alone.
The severity of a finding is the finding's credibility. Calling a style nit "must-fix" destroys trust.
Cross-Bee handoffs
- Next.js-specific SEO, metadata, sitemap →
seo-aeo-worker-bee.
- Visual design, token usage, spacing, typography →
ux-ui-worker-bee.
- Security audit of Server Actions, auth tokens, RBAC →
security-worker-bee. react-stinger surfaces security concerns; the audit is their job.
- Refactor large enough to warrant a PRD → produce the architectural rationale, hand PRD authoring to
library-worker-bee.
- Post-refactor QA →
quality-worker-bee.
The guides
Numbered so ordering is obvious. Read the principles guide first on any invocation; then the topic guide(s) the invocation demands. Guides 00–13 are the bulletproof-react core; 14–20 are the extended UI-adjacent topics react-worker-bee owns.
guides/00-principles.md — the first-move checklist, severity rubric, cross-Bee boundaries.guides/01-project-structure.md — feature-based folder layout per bulletproof-react.guides/02-components-and-composition.md — composition, compound components, API minimalism.guides/03-state-management.md — the 5-layer model (UI → global → server → URL → form) with an opinionated pick per layer.guides/04-data-layer.md — RSC vs. TanStack Query vs. SWR vs. route loaders. The 3-part request declaration.guides/05-error-handling.md — boundaries, Suspense composition, retry patterns.guides/06-forms.md — React Hook Form + Zod; React 19 Server Action forms.guides/07-performance.md — React Compiler, children-as-optimization, profiling, bundle budgets.guides/08-testing.md — Vitest + RTL + MSW + Playwright strategy.guides/09-typescript-patterns.md — strict mode, Zod at boundaries, satisfies vs. as, branded types, discriminated unions.guides/10-react-19-idioms.md — Actions, useActionState, useOptimistic, useFormStatus, the Compiler, ref-as-prop.guides/11-server-components.md — RSC mental model, client boundary placement, Server Action security.guides/12-anti-patterns.md — common anti-patterns and their canonical fixes.guides/13-ecosystem-catalog.md — opinionated picks from awesome-react per category.guides/14-forms-and-validation.md — extended form-lib choice tree (RHF vs TanStack Form, Zod vs Valibot, Conform, Formbricks).guides/15-rich-text-editors.md — TipTap / BlockNote / Lexical / Plate / ProseMirror / Novel / Yoopta choice tree.guides/16-data-grids-and-tables.md — TanStack Table / AG Grid / Handsontable / Glide Data Grid / MUI X by row count, edit depth, license tolerance.guides/17-charts-and-viz.md — Recharts / shadcn Charts / Nivo / ECharts / Tremor / Visx / Observable Plot choice tree; chart-token handoff to ux-ui-worker-bee.guides/18-dnd-and-animation.md — dnd-kit / SortableJS / Motion / GSAP / Lottie / Theatre.js / auto-animate; the DnD a11y floor.
Templates, scripts, examples
- Templates —
templates/ADR.md, templates/project-structure.md, templates/provider-stack.tsx, templates/error-boundary.tsx, templates/test-setup.ts, templates/eslint.config.js, templates/review-output-template.md.
- Scripts —
scripts/scan-anti-patterns.ts, scripts/bundle-budget-check.ts, scripts/react-version-audit.ts. Each has a header with invocation instructions.
- Examples —
examples/adr-example-server-components-boundary.md, examples/code-review-example-before-after.md, examples/refactor-proposal-example.md.
- Reports go to the host repo's
library/ tree — standalone: library/qa/react/<date>-<topic>.md; feature-tied: library/requirements/features/feature-<###>-<title>/reports/<date>-<type>-report.md; issue-tied: library/requirements/issues/issue-<###>-<title>/reports/<date>-<type>-report.md. Use templates/review-output-template.md as the starting skeleton.
Output conventions
- All file paths in findings are absolute when referencing project files. Relative when referencing guides in this Stinger.
- Every claim is sourced. Either a guide section (
guides/03-state-management.md §2.1) or an external URL.
- Do not invent package versions. Read them from
package.json.
- Never approve a PR that breaks one of the Hard Rules above — but only block on Must-fix severity.
When in doubt
- Unfamiliar stack combination? Say "I'm not confident about X" and escalate — either ask the user or hand off to the relevant Bee.
- New pattern from a blog post? Mark it "experimental" and cite the so
