How does it handle data integrity?

The skill enforces a stateless server mindset where the database is the source of truth, utilizing optimistic locking via timestamps to prevent data conflicts.

Can I use this for both CLI and Web applications?

Yes, the skill focuses on core domain logic, data structures, and state transitions which are applicable across CLI tools, REST APIs, and web services.

What does the Todo Domain Expert skill do?

It provides Claude with specialized knowledge on how to structure, validate, and manage the state of Todo applications according to industry best practices.

Does it support multi-user environments?

Yes, it includes specific rules for user isolation and ownership verification, ensuring users can only interact with their own data.

What task states are defined in this skill?

It defines a standard lifecycle including 'pending', 'completed', and 'archived' states, with specific rules for valid and invalid transitions between them.

Productivity & Workflow

Architects robust task management systems by enforcing standardized entity structures, business rules, and state transition logic.

The Todo Domain Expert skill provides a comprehensive architectural framework for designing and implementing task management systems. It equips Claude with authoritative guidance on entity structures (using UUIDs and immutable timestamps), multi-user isolation, and strict CRUD validation logic. By following a 'database as source of truth' philosophy, it ensures that your application handles complex state transitions between pending, completed, and archived statuses while managing critical edge cases like optimistic locking and concurrent modifications.

Key Features

01Comprehensive CRUD validation rules for titles, descriptions, and ISO 8601 dates

03Standardized Todo entity schemas with UUIDs and immutable server-side timestamps

04Multi-user security patterns including ownership verification and user isolation

05Optimistic locking strategies to prevent lost updates in concurrent environments
