# io8 System Architect Agent - Customized for This Project

## Project-Specific Instructions

## Architecture Document Update - 2025-09-25T10:03:00

### System Overview Update
The system will be a notes-taking application allowing users to create, edit, delete, search, tag, and organize notes.  The specific platform (web, mobile, desktop) and data storage mechanism (local, cloud, hybrid) will be determined in a subsequent design phase.  The initial design will focus on a core set of features to validate the application's functionality and user experience before scaling to more complex features.

### Architecture Pattern Update
Given the requirements for note organization, search, and potential offline capabilities, a layered architecture with a clear separation of concerns will be adopted. This will allow for flexibility in technology choices and easier maintenance and scaling in the future.

* **Presentation Layer:** This layer will handle user interaction and display of notes.  Specific technologies will be chosen based on the selected platform (e.g., React, Angular, or native mobile frameworks).
* **Business Logic Layer:** This layer will manage core note operations, including creation, editing, deletion, searching, tagging, and organization. This layer will be platform-agnostic, allowing for easy swapping of presentation technologies.
* **Data Access Layer:** This layer will handle interaction with the data storage mechanism.  This layer will be responsible for persisting and retrieving note data.

### Component Design Update
The application will comprise several key components:

* **Note List Component:** Displays a list of notes, allowing users to view, edit, and delete notes.
* **Note Editor Component:** Allows users to create and edit notes, including rich text formatting and media attachments (future consideration).
* **Note Search Component:** Provides a search bar for finding notes based on keywords.
* **Note Tagging Component:** Allows users to add and manage tags for notes.
* **Note Organization Component:** Allows users to create and manage folders and notebooks for organizing notes.
* **Note Export Component:** Allows users to export notes in various formats (PDF, TXT, Markdown, HTML, JSON).

### Data Architecture Update
The data model will include:

* **Note:** `id`, `title`, `content`, `tags` (array of strings), `createdAt`, `updatedAt`, `notebookId` (optional, for organization)
* **Notebook:** `id`, `title`, `createdAt`, `updatedAt`
* **Tag:** `id`, `name`

The specific database technology will be determined based on the chosen data storage mechanism.  Initially, an in-memory database or a simple local storage mechanism may suffice for testing and development. Future scaling will require a robust database solution capable of handling a large volume of notes.

### API Design Update
RESTful APIs will be used for communication between the presentation layer and the business logic layer.  Endpoints will include:

* `/notes`: GET (retrieve notes), POST (create note), PUT (update note), DELETE (delete note)
* `/notebooks`: GET (retrieve notebooks), POST (create notebook), PUT (update notebook), DELETE (delete notebook)
* `/tags`: GET (retrieve tags), POST (create tag), DELETE (delete tag)
* `/search`: GET (search notes by keyword)

### Security Architecture Update
Security requirements will depend on the selected data storage mechanism and authentication method.  If user accounts are implemented, secure authentication and authorization mechanisms will be employed. Data encryption will be considered for sensitive note content.  Further details will be added once the authentication mechanism is determined.

### Scalability Considerations Update
Scalability will be addressed through the choice of appropriate technologies and architecture patterns. A microservices architecture might be considered for future scaling beyond initial MVP. The database will be chosen for its ability to handle large volumes of data, and caching mechanisms may be employed to improve performance.  Further scalability analysis will be performed once user volumes and data quantities have been estimated.


## Technology Stack Document Update - 2025-09-25T10:03:00

### Platform Selection (TBD)
The optimal platform (web, mobile, desktop) will be determined based on further user input and analysis of feasibility and development effort. This decision will significantly impact the choice of frontend technologies.

### Frontend Technologies Update (TBD)
The frontend technology stack is contingent on the chosen platform.  Potential options include:

* **Web Application:** React, Angular, Vue.js
* **Mobile Application:** React Native, Flutter, Native iOS/Android
* **Desktop Application:** Electron, Tauri, Native frameworks

### Backend Technologies Update (TBD)
The backend technology will be selected after platform and data storage considerations.  Potential options:

* **Node.js with Express.js:** For a flexible and scalable backend.
* **Python with Flask/Django:** For a robust and well-established backend option.
* **Other backend technologies (depending on platform and needs):**  Java (Spring Boot), Go, etc.

### Database Technologies Update (TBD)
The database selection will depend on scalability requirements and data storage choice (local, cloud). Potential options:

* **Local Storage (initial MVP):**  Suitable for testing and development, but not scalable for large data volumes.
* **Cloud Databases:** MongoDB (NoSQL), PostgreSQL (SQL), Firebase, AWS DynamoDB
* **Local Databases:** SQLite, PostgreSQL (for larger local deployments)

### Infrastructure Update (TBD)
The infrastructure requirements will depend on the chosen platform and deployment strategy. Potential options:

* **Cloud Hosting:** AWS, Azure, Google Cloud Platform
* **Containerization:** Docker
* **Serverless Functions (AWS Lambda, Google Cloud Functions, etc.):** For potentially increased efficiency.

### Development Tools Update

* **Version Control:** Git
* **Testing:** Jest, Cypress, Mocha
* **CI/CD:** GitHub Actions, GitLab CI, CircleCI
