SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill bridges the gap between planning and execution by automatically writing feature code and comprehensive tests based on tasks defined in Plans.md, drastically reducing manual coding time.

Core Features & Use Cases

  • Automated Feature Implementation: Reads Plans.md, updates task status, and writes the actual code for new features, components, or API endpoints.
  • Intelligent Test Generation: Creates robust unit and integration tests for implemented code, ensuring quality and preventing regressions.
  • Use Case: Have a task "Add user profile page" marked as cc:TODO? The /work command uses this Skill to read the plan, create the React component and backend route, write tests, and update the task status to cc:完了—all automatically.

Quick Start

Execute the /work command in Claude Code to automatically pick up the next cc:TODO task from Plans.md and begin implementation.

FAQPage Schema
How do I automatically implement features from a plan into my Next.js codebase?

Automated feature implementation reads tasks from `Plans.md`, generates React components, API endpoints, and backend routes, then writes tests and updates task status. Execute the `/work` command to pick up the next `cc:TODO` task and implement it end-to-end with code generation and test creation.

Can I generate tests automatically when implementing new code?

Yes. Intelligent test generation creates unit and integration tests for implemented features, ensuring quality and preventing regressions. Tests are written alongside feature code during the implementation process.

What frameworks and languages does this implementation Skill support?

Implementation targets Next.js and TypeScript stacks, handling API endpoints, UI components, utilities, and tests within that environment. LSP-based verification ensures code quality during and after generation.

How do I track the status of implemented tasks?

Task status updates are handled automatically during implementation. Tasks marked as `cc:TODO` in `Plans.md` transition to `cc:完了` upon successful feature completion and test generation.

Does this Skill work with existing code patterns and memory?

Yes. The Skill uses memory-enabled past-pattern references to apply existing code conventions and architectural patterns, ensuring new implementations align with your codebase's established style.

What's the best way to structure plans for automated implementation?

Define tasks in `Plans.md` with clear descriptions and mark them as `cc:TODO`. The Skill reads these structured plans and automatically generates corresponding code, components, routes, and tests based on the specifications provided.
