Create an actionable Laravel implementation plan—bite-sized tasks with TDD-first steps, migrations, services, jobs, and validation points
Pre-deployment validation for Webflow Code Components. Checks bundle size, dependencies, prop configurations, SSR compatibility, styling setup, and common issues before running webflow library share.
Zod 4 — TypeScript-first schema validation with static type inference. Use when writing Zod schemas, validating data, defining types with Zod, parsing input, creating form validation schemas, defining API request/response schemas, working with z.object, z.string, z.number, z.enum, z.array, z.union, z.discriminatedUnion, z.file, z.jwt, z.email, z.uuid, z.url, z.codec, z.toJSONSchema, z.fromJSONSchema, z.int, z.stringbool, z.templateLiteral, z.record, z.partialRecord, or any other Zod API. Also use when migrating from Zod 3 to Zod 4, or when the user's package.json shows zod@^4. CRITICAL: Always use Zod 4 APIs. Never use deprecated Zod 3 patterns unless user explicitly requests Zod 3 compatibility.
Implement, configure, and debug Unity In-App Purchases (IAP) — store connection, product catalog, consumable/non-consumable/subscription purchases, two-step pending-confirm flow, receipt validation, entitlement checking, restore transactions, Apple extensions (promotional purchases, Ask-to-Buy, code redemption), and Google Play extensions (subscription upgrade/downgrade), D2C Capabilities(direct to customer), 3rd party payment provider (Stripe/Coda) via Unity IAP/Unity Cloud. Use when the user needs to add, modify, debug, or migrate from native Android/iOS billing, 3rd party packages(RevenueCat/Adapty/Essential Kit/Unipay supported) to IAP. Triggers on microtransactions (MTX), monetization, real-money purchases, store purchases, buying items, support D2C, purchase via Stripe/Coda, migrate from native billing(Google's BillingClient or Apple's StoreKit/SKPaymentQueue/SKProduct)/RevenueCat/Adapty/EssentialKit/Unipay.
Refactor Pandas code to improve maintainability, readability, and performance. Identifies and fixes loops/.iterrows() that should be vectorized, overuse of .apply() where vectorized alternatives exist, chained indexing patterns, inplace=True usage, inefficient dtypes, missing method chaining opportunities, complex filters, merge operations without validation, and SettingWithCopyWarning patterns. Applies Pandas 2.0+ features including PyArrow backend, Copy-on-Write, vectorized operations, method chaining, .query()/.eval(), optimized dtypes, and pipeline patterns.
Debug NestJS issues systematically. Use when encountering dependency injection errors like "Nest can't resolve dependencies", module import issues, circular dependencies between services or modules, guard and interceptor problems, decorator configuration issues, microservice communication errors, WebSocket gateway failures, pipe validation errors, or any NestJS-specific runtime issues requiring diagnosis.
Multi-layer validation pattern - validates data at EVERY layer it passes through to make bugs structurally impossible, not just caught.
Development cycle validation gate (Gate 5) - validates all acceptance criteria are met and requires explicit user approval before completion.
Use when designing Rails models - ActiveRecord patterns, validations, callbacks, scopes, associations, concerns, query objects, form objects
Initialize, build, and deploy full-stack Webflow applications to Webflow Cloud hosting. List available templates, initialize projects with cloud init, and deploy with comprehensive validation. Use when creating or deploying Webflow Cloud applications.
Knowledge and utilities for creating animated GIFs optimized for Slack. Provides constraints, validation tools, and animation concepts. Use when users request animated GIFs for Slack like "make me a GIF of X doing Y for Slack."
