Expert micro-interaction architect for mobile apps, web applications, and responsive websites. Use this skill when the user asks to add, build, fix, audit, or consult on micro-interactions, animations, transitions, motion design, gesture feedback, haptics, loading states, skeleton screens, pull-to-refresh, swipe actions, scroll animations, button states, form validation feedback, toast notifications, modals, dropdowns, toggles, progress indicators, shared element transitions, spring physics, easing curves, motion tokens, or any interaction that provides visual/haptic/auditory feedback to user actions. Triggers on: "micro-interaction", "animation", "transition", "motion", "easing", "spring", "gesture", "haptic", "feedback", "loading state", "skeleton", "shimmer", "pull to refresh", "swipe", "drag", "hover effect", "press state", "focus ring", "scroll animation", "parallax", "stagger", "orchestration", "reduced motion", "View Transitions", "layout animation", "shared element", "hero animation", "morphing", "Framer Motion", "GSAP", "Lottie", "Rive", "React Spring", "anime.js", or any request to make an interface "feel better", "feel alive", "feel snappy", "feel responsive", or "feel polished".
Intelligent loading performance analysis with automated workflows for TTFB investigation (DNS/connection/server breakdown), render-blocking detection, script performance deep dive (first vs third-party attribution), font optimization, and resource hints validation. Includes decision trees that automatically analyze TTFB sub-parts when slow, detect script loading anti-patterns (async/defer/preload conflicts), identify render-blocking resources, and validate resource hints usage. Features workflows for complete loading audit (6 phases), backend performance investigation, and priority optimization. Cross-skill integration with Core Web Vitals (LCP resource loading), Interaction (script execution blocking), and Media (lazy loading strategy). Use when the user asks about TTFB, FCP, render-blocking, slow loading, font performance, script optimization, or resource hints. Compatible with Chrome DevTools MCP.
Use when completing a task, implementing a feature, or before committing to verify work meets requirements and coding standards. Triggers: task completion, pre-commit check, pre-merge validation, plan alignment verification, post-refactor quality gate.
Guide the design and implementation of order lifecycle management in trading systems. Use when building an order state machine for an OMS or EMS, implementing or debugging FIX protocol connectivity to exchanges, handling cancel/replace race conditions, defining pre-submission validation rules (buying power, position limits, restricted lists), selecting order types and time-in-force instructions, designing multi-leg or OCO or bracket orders, building CAT-compliant audit trails, troubleshooting order rejections or unexpected state transitions, hardening an OMS against edge cases, or implementing order persistence and recovery for failover. Also covers FIX message flows, ClOrdID chaining, and partial fill aggregation.
Use when building or maintaining Laravel applications — Eloquent ORM, Blade, Livewire, queues, Pest testing, middleware, service providers, migrations. Trigger conditions: Laravel project setup, Eloquent model design, Blade or Livewire component creation, queue/job implementation, Pest test writing, middleware configuration, migration authoring, route definition, Form Request validation, policy authorization, Sanctum/Passport authentication, Horizon queue monitoring.
Use when the user needs Excel file manipulation — reading, writing, formulas, charts, conditional formatting, data validation, pivot tables, or large file handling. Trigger conditions: create Excel reports programmatically, read spreadsheet data, add formulas or charts, apply conditional formatting, perform data validation, generate pivot tables, handle CSV import/export, process large datasets in Excel format.
Run bean-check plus custom validation rules on the ledger. Ensures every entry balances, accounts exist, and no common errors are present. Use after any ledger modification to verify integrity. CLEAR step: L (Log)
Define reusable Airflow task group templates with Pydantic validation and compose DAGs from YAML. Use when creating blueprint templates, composing DAGs from YAML, validating configurations, or enabling no-code DAG authoring for non-engineers.
Use this skill whenever writing, reviewing, debugging, or refactoring TypeScript code that uses the Effect-TS library. Trigger when you see imports from `effect`, `effect/*`, or any `@effect/*` scoped package (schema, platform, sql, opentelemetry, cli, cluster, rpc, vitest). Trigger on Effect-specific constructs: Effect.gen generators, Schema.Struct/Schema.Class definitions, Layer/Context.Tag/Service patterns, Effect.pipe pipelines, Data.TaggedError/Data.Class error types, Ref/Queue/PubSub/Deferred concurrency primitives, Match module, Config providers, Scope/Exit/Cause/Runtime patterns, or any code using Effect's typed error channel (E parameter). Also trigger when the user asks about Effect patterns, migration from Promises/fp-ts/neverthrow to Effect, or how to structure an Effect application. Covers the full ecosystem: core Effect type, Schema validation, error management, concurrency (fibers, queues, semaphores, pools), streams/sinks, services and layers (DI), resource management, scheduling, observability, platform APIs, and AI integration. Do NOT trigger for React's useEffect, Redux side effects, or general English usage of "effect" unless the context clearly involves the Effect-TS library.
[Pragmatic DDD Architecture] Guide for creating Next.js Server Actions exactly tied to zod, neverthrow, and the domain architecture. Use when creating or editing any file in presentation/actions/. Covers "use server" placement, unknown parameters validated with `zod`, discriminated union response types, auth-first pattern, Value Object validation with TypeScript narrowing, use-case error mapping via `assertNever`, serviceContainer invocation, and revalidation strategy.
Conducts security testing of REST, GraphQL, and gRPC APIs to identify vulnerabilities in authentication, authorization, rate limiting, input validation, and business logic. The tester uses the OWASP API Security Top 10 as the testing framework, combining Burp Suite interception with Postman collections and custom scripts to test endpoint security at every privilege level. Activates for requests involving API security testing, REST API pentest, GraphQL security assessment, or API vulnerability testing.
Use this before claiming work is complete, fixed, or tested—before committing or creating a PR—you must run validation commands and confirm the output before claiming success; always back up assertions with evidence
