"performance-optimization" 사용 중입니다. The page has LCP of 4.2 seconds, a 1.8 MB JavaScript bundle, and large hero images.
예상 결과:
"performance-optimization" 사용 중입니다. An API loads tasks and fetches each task owner separately.
예상 결과:
This is an N+1 query pattern. Fetch tasks with their owners in one query, then compare query count and p95 latency before and after.
"performance-optimization" 사용 중입니다. A cache serves user profiles by profile ID, but the response includes tenant-specific permissions.
예상 결과:
The cache key omits a response input. Include tenant and permission context, or avoid shared caching when authorization data must remain isolated.

Use measured browser data to identify bundle, rendering, image, interaction, or server-response bottlenecks.
Review query plans, indexes, pagination, N+1 patterns, and connection pools before changing backend code.
Create performance budgets and monitoring checks that verify improvements and catch later regressions.
My application feels slow. Ask for the minimum data needed, then identify the first measurements I should collect.
Review these LCP, INP, CLS, bundle, and network results. Identify the most likely bottleneck and propose one testable fix.
Analyze this query and EXPLAIN ANALYZE output. Explain the bottleneck, evaluate index options, and state the measurement needed after the change.
Design a controlled performance experiment for this suspected bottleneck. Define the baseline, one change, success threshold, variance check, rollback rule, and regression guard.

Clarify User Intent Before You Build
Underspecified requests cause teams to build the wrong outcome and discover misalignment late. This skill runs a focused, one-question interview that turns ambiguity into confirmed intent.
Revisar código según cinco ejes de calidad
Los cambios de código pueden ocultar problemas de corrección, seguridad, arquitectura, legibilidad y rendimiento. Esta habilidad aplica un proceso de revisión estructurado y genera comentarios priorizados y prácticos.
Plan Work Into Verifiable Tasks
Large or vague software work can hide dependencies, missing acceptance criteria, and verification gaps. This skill converts a specification into ordered task slices with checkpoints, scope guidance, and clear completion conditions.
Document Decisions and Architecture Clearly
Teams lose context when important technical decisions remain in chat, code comments, or individual memory. This skill turns architectural reasoning, API guidance, project instructions, and release changes into structured documentation.
Build Accessible, Production-Ready Frontends
Frontend work can become inconsistent, inaccessible, or difficult to maintain. This skill guides component architecture, responsive layouts, state handling, and polished user experiences.
Harden Applications Against Security Risks
Security reviews can miss trust boundaries and unsafe data flows. This skill supplies threat-modeling prompts, OWASP patterns, and practical review checklists.
Build Interactive Three.js Scenes
작성자 freshtechbro
Building browser-based 3D scenes requires coordinating rendering, assets, interaction, and performance. This skill provides Three.js examples, reference guides, and a WebGL starter to support implementation.
Mejorar la calidad del código Vue 3
작성자 vuejs-ai
Los proyectos Vue suelen acumular errores de reactividad, componentes y rendimiento con el tiempo. Esta skill ofrece orientación específica de Vue 3 para patrones más seguros y código más claro.
Optimiza el rendimiento de Go con perfilado
작성자 89jobrien
Los servicios Go pueden volverse lentos o consumir mucha memoria sin evidencia clara. Esta skill guía el perfilado, el análisis de asignaciones, el ajuste de concurrencia y la optimización basada en benchmarks.
Crea mejores funcionalidades con SwiftUI
작성자 avdlee
Los proyectos de SwiftUI pueden acumular API obsoletas, estado frágil y actualizaciones de vista lentas. Esta habilidad ofrece orientación enfocada para escribir código SwiftUI moderno y mantenible.
Desarrolla funcionalidades frontend listas para producción
