Error Boundaries เป็นคุณลักษณะที่สำคัญใน React ที่ช่วยจัดการข้อผิดพลาด (Error Handling) ในแอปพลิเคชัน React โดยการจับ JavaScript errors ที่เกิดขึ้นใน component tree และแสดง fallback UI แทนที่จะทำให้ทั

errors

Guides users on error conversion patterns, From trait implementations, and the ? operator. Activates when users need to convert between error types or handle multiple error types in a function.

Standard protocols for handling errors, API failures, and infrastructure issues

Errors are inevitable. The difference between a frustrating product and a caring one is how you handle them. This skill teaches you to design error states that guide users to resolution rather than le

Effect distinguishes between two types of failures:

Error Pattern Safety Guidelines for Agentic Engines

Engineer resilient UI systems with layered error boundaries, retries, and fallback orchestration.

Error recovery and failure handling patterns for distributed systems including rollback strategies, circuit breakers, retry logic with exponential backoff, graceful degradation, and compensating transactions. Activates when task execution fails, timeouts occur, external services fail, database transactions fail, or cascade failure risks are detected. Use when recovering from failures, preventing data corruption, implementing resilience patterns, or handling partial system failures.

Clear escalation procedures and paths for incident response

Manages practice rules. Use when user states a preference or approach, or asks to add/modify rules for coding, architecture, tooling, or best practices.

Set up ESP-IDF development environment, create new projects, and configure build systems

Create and configure ESPHome devices for DIY smart home sensors and actuators. Write YAML configurations for ESP8266/ESP32 boards, sensors, displays, and automations. Use when building custom IoT devices, flashing ESPHome firmware, or integrating with Home Assistant. (project)

Comprehensive guide for developing on EspoCRM - metadata-driven CRM with service layer architecture

Calculate story point estimates for user stories using structured formula (Complexity × Effort + Risk). Analyzes acceptance criteria, assesses complexity (1-5), effort (1-5), and risk (0-3), then documents estimation rationale. Use during backlog grooming or sprint planning when stories need sizing.

Master Ethereum development including EVM, gas optimization, and client interactions

Expert guidelines for Ethereum smart contract development with Solidity, OpenZeppelin, and Hardhat

Enables Claude to browse Etsy products, manage favorites, and explore handmade items

Control eufy smart home devices including cameras, doorbells, and robot vacuums

Help users evaluate emerging technologies. Use when someone is assessing new tools, making build vs buy decisions, evaluating AI vendors, or deciding on technical architecture.

Evaluate trade-offs and produce a Trade-off Evaluation Pack (trade-off brief, options+criteria matrix, all-in cost/opportunity cost table, impact ranges, recommendation, stop/continue triggers). Use for tradeoff/trade-off, pros and cons, cost-benefit, opportunity cost, build vs buy, ship fast vs ship better, continue vs stop (sunk costs). Category: Leadership.

Use when need explicit quality criteria and scoring scales to evaluate work consistently, compare alternatives objectively, set acceptance thresholds, reduce subjective bias, or when user mentions rubric, scoring criteria, quality standards, evaluation framework, inter-rater reliability, or grade/assess work.

Build evaluation frameworks for agent systems

Event-driven architecture patterns with event sourcing, CQRS, and message-driven communication. Use when designing distributed systems, microservices communication, or systems requiring eventual consistency and scalability.

Add new events to Bob The Skull's event-driven architecture. Use when creating new events, event publishers, event handlers, or extending the event system with new event types.

为Flutter插件视图添加事件监听容器，自动管理事件订阅/取消订阅生命周期，避免内存泄漏并减少约84%的模板代码。适用场景：(1) 插件视图需要响应全局事件更新UI，(2) 需要避免手动管理订阅导致的内存泄漏，(3) 简化事件监听实现

JSONL event stream for external integrations and hooks

Adam Dymitruk's Event Modeling methodology with swimlanes

Event sourcing patterns and design decisions

Implement event sourcing and CQRS patterns using event stores, aggregates, and projections. Use when building audit trails, temporal queries, or systems requiring full history.

Handle event sponsorship inquiries. Use when organizers ask for sponsorship or support for conferences or hackathons.

Deep dive Event Storming beyond big picture

AI-simulated event storming workshop with multi-persona support. Use when discovering domain events, commands, actors, and bounded contexts. Supports three modes - full-simulation (5 persona agents debate), quick (single-pass analysis), and guided (interactive with user). Orchestrates persona agents and synthesizes results.

AWS EventBridge serverless event bus for event-driven architectures. Use when creating rules, configuring event patterns, setting up scheduled events, integrating with SaaS, or building cross-account event routing.

Plan and manage security evidence collection for compliance audits and assessments. Use this skill to identify required evidence, track collection status, and ensure audit readiness.
