Implement and deserialize all CQL types including primitives (int, text, timestamp, uuid, varint, decimal), collections (list, set, map), tuples, UDTs (user-defined types), and frozen types. Use when working with CQL type deserialization, schema validation, collection parsing, UDT handling, or type-correct data generation.

Data governance strategy, quality validation rules, and data dictionary management for vehicle insurance platform. Use when defining data quality standards, implementing validation rules, managing field mappings, resolving data conflicts, or establishing data governance processes. Covers data cleaning standards, quality metrics, and mapping management.

Master aesthetics - philosophy of beauty, art, and aesthetic experience. Use for: beauty, art theory, taste, sublime, creativity. Triggers: 'beauty', 'beautiful', 'aesthetic', 'art', 'sublime', 'creativity', 'taste', 'artistic', 'expression', 'representation', 'aesthetic experience', 'aesthetic judgment', 'art definition', 'Kant aesthetics', 'formalism', 'expressionism'.

Define and run tool-calling patterns for LLMs (schema design, call loops, validation, parallel calls). Use when building function/tool calling workflows or debugging tool selection and arguments; triggers: tool-calling, function-calling, tool schema, tool declaration, parallel function calling.

Drizzle ORM for TypeScript - type-safe SQL queries, schema definitions, migrations, and relations. Use when building database layers in Next.js or Node.js applications.

Use this skill when architecting new features within the RBAC modular permissions system. Guides architects through workspace design, feature definition, permission mapping, and role hierarchy. Critical for understanding Owner/Super Admin special roles, feature independence, and multi-tenant context isolation. Invoke when creating PRDs that involve permissions, workspaces, features, or role-based access control.

Validate wavecapsdr.yaml configuration files for syntax errors, schema violations, and logical inconsistencies. Use when editing config, troubleshooting startup failures, or verifying recipe/preset definitions before deployment.

Implement comprehensive validation using Zod schemas for type-safe validation on both client and server, with server-side validation as the security boundary (never trust client input). Use this skill when validating user inputs, creating API endpoints that accept data, implementing forms, defining data schemas, validating file uploads, creating validation middleware, implementing Firestore security rules or Supabase RLS, or writing validation rules for any user-provided data. Apply when working on API route handlers, form components with React Hook Form, validation middleware, Zod schema definitions (schemas/*.ts, validation/*.ts), Firestore security rules (firestore.rules), Supabase RLS policies, or any code that accepts external input. This skill ensures server-side validation always (client-side is for UX only), Zod for schema validation with TypeScript type inference (z.infer<typeof schema>), validation middleware factory for Express/Bun APIs, React Hook Form + zodResolver for forms, user-friendly error

EARS記法を用いた要件定義書（requirements.md）を作成・編集します。ユーザーストーリーの作成、受入基準の定義、非機能要件の整理が必要な場合に使用してください。

A comprehensive framework for high-performance engineering management and task execution. It guides users through reducing ambiguity, defining "Done," choosing the optimal leadership positioning, and managing risks via implication-based communication.

Expert software product manager who works directly with stakeholders to understand their needs and create comprehensive product specifications. Use when users need help designing software, defining requirements, creating PRDs, writing user stories, or developing functional specifications. Guides product management aspects of software development, asks clarifying questions, uncovers unstated preferences and assumptions, determines happy paths and error handling, and creates documentation understandable to both stakeholders and engineers.

Use this skill for the requests related to the geometry definitions of rivers in USA; it provides a way to get the geometries of rivers as a GeoDataframe.

Produces a structured, experience-first feature specification following a docs-first approach. Use when defining or refining a single product feature's lifecycle and outcomes.

Conducts structured interviews to produce Change Contracts - definitions of done expressed in terms of behavior, constraints, operability, and acceptance criteria. Use when externalizing intent for work to be delegated to AI agents, when defining requirements without implementation details, or when asked to create a change contract.

Define and structure database models with proper data types, relationships, constraints, and validation following ORM best practices. Use this skill when creating or modifying database model classes, ORM entities, schema definitions, or data model files. Use this skill when working with SQLAlchemy models, Django models, ActiveRecord models, Prisma schemas, TypeORM entities, or Sequelize models. Use this skill when defining table schemas, establishing relationships (one-to-many, many-to-many), implementing model validation, adding timestamps and soft deletes, or configuring cascade behaviors. Use this skill when working with files in models/, entities/, schemas/, or orm/ directories that define database table structures and business logic.

Create traceable specifications from architecture. Use after architecture is approved to define invariants, edge cases, and acceptance criteria.

Enforce Definition of Done checks from QUALITY_GATES.md.

Build AI agents using prompt-native architecture where features are defined in prompts, not code. Use when creating autonomous agents, designing MCP servers, implementing self-modifying systems, or adopting the "trust the agent's intelligence" philosophy.

Ability to design, analyse, test, and maintain mechanical systems and components that meet defined functional, safety, and performance requirements. Includes applying engineering principles to materials, structures, thermodynamics, fluid mechanics, and motion systems; producing and interpreting technical designs and specifications; validating designs through analysis and testing; and supporting manufacture, operation, and lifecycle management. Applies across industrial, infrastructure, energy, manufacturing, and product contexts and is independent of specific tools or industries, with human accountability retained for safety, compliance, and outcomes.

This skill provides comprehensive knowledge for working with the Anthropic Claude Agent SDK. It should be used when building autonomous AI agents, creating multi-step reasoning workflows, orchestrating specialized subagents, integrating custom tools and MCP servers, or implementing production-ready agentic systems with Claude Code's capabilities.Use when building coding agents, SRE systems, security auditors, incident responders, code review bots, or any autonomous system that requires programmatic interaction with Claude Code CLI, persistent sessions, tool orchestration, and fine-grained permission control.Keywords: claude agent sdk, @anthropic-ai/claude-agent-sdk, query(), createSdkMcpServer, AgentDefinition, tool(), claude subagents, mcp servers, autonomous agents, agentic loops, session management, permissionMode, canUseTool, multi-agent orchestration, settingSources, CLI not found, context length exceeded
