DeFi

Reference the project's defined technology stack including frameworks, languages, databases, testing tools, and deployment infrastructure. Use this skill when making technology decisions or choosing libraries. When working with project configuration files like package.json, requirements.txt, or Gemfile. When setting up new features that need to align with existing technology choices. When onboarding to understand the project's technical foundation. When choosing tools for testing, linting, CI/CD, or third-party services.

Generate diagrams and flowcharts from mermaid definitions using the mermaid-cli (mmdc). Supports themes, custom CSS, and various output formats including SVG, PNG, and PDF. Mermaid supports 20+ diagram types including flowcharts, sequence diagrams, class diagrams, state diagrams, entity relationship diagrams, user journeys, Gantt charts, pie charts, quadrant charts, requirement diagrams, GitGraph, C4 diagrams, mindmaps, timelines, ZenUML, Sankey diagrams, XY charts, block diagrams, packet diagrams, Kanban boards, architecture diagrams, radar charts, and treemaps. This skill is triggered when the user says things like "create a diagram", "make a flowchart", "generate a sequence diagram", "create a mermaid chart", "visualize this as a diagram", "render mermaid code", or "create an architecture diagram".

Structure React 19+ components following best practices for organization, state management, props handling, and code readability with top-down structure and single responsibility principle. Use this skill when creating new React components, refactoring existing components, organizing component logic, managing component state, defining prop interfaces (IComponentProps with I prefix), or implementing component patterns. Apply when working on React component files (*.tsx, *.jsx), Shadcn/ui components, or any frontend component implementations. This skill ensures predictable top-down structure (imports → types/interfaces → component → hooks → derived values → JSX), proper props destructuring with defaults in function signature, manageable component size (split at >300 lines), composition via Shadcn Slot pattern (asChild prop), React 19 patterns (use() hook for promises, useActionState for forms, useOptimistic for immediate feedback), no manual useMemo/useCallback (React Compiler handles memoization), Server Compo

Updates skills during project work according to their contracts. Adds references, improves explanations, and refines examples while respecting skill boundaries. Use when discovering patterns, encountering edge cases, or finding better ways to explain skill concepts. Works with skills that have Skill Contracts defined by skill-contract-generator.

Defines project-wide code conventions for magic number elimination, constant usage, performance optimization, and type safety. Use when implementing, testing, or reviewing code to ensure consistency across the codebase.

PostgreSQL schema design with SQLModel. Use when designing database schemas, creating ERDs, defining models, planning migrations, or reviewing table structures. Triggers on tasks involving database tables, relationships, indexes, or data modeling for PostgreSQL.

Guide for authoring, designing, building, writing, and developing specialized AI agents. Use when creating, updating, reviewing, or improving agents that handle specific tasks with focused expertise. Helps design AGENT.md files, choose models (Sonnet/Haiku/Opus), define focus areas, configure tool restrictions, and decide between agents, skills, and commands. Expert in agent validation, best practices, and troubleshooting.

Use when designing database schemas from business requirements, translating vague requirements into concrete SQL definitions, or validating database designs with non-technical stakeholders. Provides a systematic methodology that decouples logical business modeling from physical implementation to reduce cognitive load and ensure business-driven design.

Define database models, schemas, and ORM mappings with proper relationships, constraints, and data integrity rules. Use this skill when creating or modifying ORM model classes, database schema definitions, model relationships, validators, or working with files like models.py, schema.prisma, entity classes, or Sequelize/TypeORM/ActiveRecord model definitions. Apply this skill when defining primary keys, foreign keys, indexes, unique constraints, timestamps, or when implementing model validation logic, serializers, and data type mappings. This skill ensures models follow naming conventions, include appropriate database constraints, define clear relationships with cascade behaviors, balance normalization with performance needs, and maintain data integrity at both the model and database levels.

Generate structured LaTeX exam cheat sheets from course materials. Extracts key concepts, definitions, formulas from PDFs, Jupyter notebooks, and markdown files. Compiles to PDF with error checking.

Skill for creating and editing Vue.js components following Prowi conventions. Use when writing Vue files, creating components, or refactoring frontend code. Enforces modern patterns like defineModel(), TypeScript, and Composition API.

Defines the autonomous development workflow. Use when orchestrating work between agents, managing issue lifecycles, or understanding the development loop.

Implement feature code to make BDD scenarios pass. Write production code that satisfies Given/When/Then scenarios. Use after implement-step-definitions when step definitions exist but scenarios are failing.

Defines the project's holistic quality strategy, test policies, and the 'Unified Feedback Protocol'. Establishes the single source of truth for all quality assurance procedures, unifying both automated and human-driven governance.

Rigorously critique concept designs through intellectual scrutiny. This skill should be used when validating concept definitions, reviewing concept quality, identifying design flaws, or evaluating whether something qualifies as a true concept. Applies demanding standards from Daniel Jackson's methodology. Handles queries like "critique this concept", "is this a good concept", "review my concept design", "does this meet concept criteria".

Define and structure database models with proper naming conventions, data integrity constraints, and relationship definitions. Use this skill when creating or modifying database model files, defining table schemas, setting up model relationships (one-to-many, many-to-many, one-to-one), working with ORM model files (schema.prisma, models/*, app/models/*, entities/*), implementing data validation at the model level, adding timestamps and audit fields, defining foreign keys and indexes, choosing appropriate data types, configuring cascade behaviors, or balancing database normalization with query performance. Apply this skill when designing database schemas, creating new models, refactoring existing model structures, or reviewing data integrity and relationship configurations.

BI fundamentals with metric definition, KPI calculation, dimensional modeling, dashboard optimization, and data storytelling. 40+ metric examples and calculation patterns.
