Feature Specification Document

1. Overview

Feature: Automated Task Prioritization based on Deadline & Difficulty

This feature introduces an automated system that prioritizes user tasks within the app by analyzing both the task deadlines and difficulty levels. It is designed to help busy individuals—such as students, professionals, and users juggling multiple projects—manage their workload more effectively by dynamically sorting tasks according to priority. Users will also retain control by having the ability to override the automated priority.

2. Goals

Problems Solved

• Time-management challenges: Users often struggle to determine which tasks to focus on when managing multiple deadlines.
• Cognitive overload: Difficulty balancing task urgency and complexity can lead to procrastination or missed deadlines.
• Manual prioritization effort: Users need a convenient, data-driven system to reduce the effort of manual sorting.

Opportunities Created

• Improved productivity: Users can spend more time executing tasks rather than planning.
• User engagement: Dynamic, context-aware task lists can increase app usage and satisfaction.
• Support for decision making: Providing data-backed prioritization guides users in workload balancing.

Success Metrics

• Priority feature adoption rate: Percentage of active users engaging with this prioritization feature.
• User satisfaction: Feedback ratings and NPS related to task management improvements.
• Task completion rate: Increase in timely completion of high-priority tasks.
• Override usage: Frequency of users manually adjusting the automated priority, indicating control balance.

3. User Stories

• US1:
  As a busy professional, I want my tasks automatically prioritized by approaching deadlines and difficulty so that I can focus on the most urgent and challenging work first.

• US2:
  As a student, I want to see my tasks sorted by priority so that I can plan my study sessions efficiently and avoid last-minute cramming.

• US3:
  As a multi-project manager, I want to override the system’s priority for specific tasks so that I can customize task order based on context only I understand.

• US4:
  As a regular user, I want the task list to update priorities in real-time when I change deadlines or difficulty so that I always have the latest recommended order.

4. Acceptance Criteria

5. Technical Design

Data Model

• Extend task object schema with:
  • Deadline: Date/time field (existing or confirmed).
  • Difficulty: Enum or integer scale (e.g., 1–5) set by user or default.
  • Priority: Computed numeric score stored transiently or persistently.
  • Manual Override Flag & Value: Boolean and optional priority value.

Prioritization Algorithm

• Simple weighted scoring function:
  Priority Score = W1 * (1 / Days until deadline) + W2 * Difficulty
  
  • Weights (W1, W2) configurable to balance urgency vs complexity (initial default: equal weights).
• If manual override present, use override value instead.

Architecture & Flow

• Client-side:

  • Trigger priority recalculation upon task creation or updates (deadline/difficulty/manual priority).
  • UI renders tasks sorted by priority with visual indicators.

• Server-side:

  • Store additional fields in the database schema.
  • Optionally, pre-calculate priorities on server for performance and sync with clients via API.

Integration

• Utilize existing task data storage and APIs.
• Add difficulty input in task creation/edit UI.
• Update task list components to support priority sorting and override controls.

Performance & Scalability

• Algorithm is compute-light and can run on client or server with minimal latency.
• Real-time updates implemented using event-driven updates or polling with debounce to reduce overhead.

Security & Privacy

• No additional sensitive user data collected.
• Ensure priority data respects existing authorization and data access layers.

6. Future Considerations

• Advanced AI prioritization: Integrate machine learning to adapt weights based on user behavior and historical completion rates.
• Additional factors: Incorporate other inputs like estimated task duration, user energy levels, or task dependencies.
• Cross-device sync: Real-time priority syncing across multiple devices with conflict resolution.
• Notifications: Priority-driven reminders and alerts.
• Visualization: Gantt charts or heatmaps showing priority trends and workload distribution.
• Bulk override: Allow users to batch override priorities for groups of tasks (e.g., by project or tag).

Estimated Development Effort: 25 days

Certainly! Here’s a detailed profile for a compelling main antagonist in a dystopian YA novel — a charismatic revolutionary whose noble beginnings devolve into tyranny.

Character Name:

Elara Voss

Role:

Main antagonist — charismatic revolutionary turned tyrant

Physical Description:

• Age: Mid-30s
• Height: 5'8"
• Build: Lean but athletic, with a presence that commands attention
• Hair: Jet black, usually pulled back into a tight braid or bun, signifying discipline
• Eyes: Piercing grey, almost silver — often described as “hypnotic” and unsettling
• Skin: Olive-toned with faint scars on her wrists and jawline—remnants from early battles and confrontations
• Distinguishing features: A small, deliberate tattoo of an ancient emblem (a phoenix) on the inside of her left wrist, symbolizing rebirth and revolution

Backstory:

Elara grew up in the decaying slums of the dystopian city-state of Aurea. Her parents were community organizers killed during a violent crackdown by the authoritarian government when she was just 12. Witnessing the cruelty and corruption firsthand, Elara vowed to dismantle the regime that stole her family and crushed hope.

She spent her teenage years in underground resistance cells, rapidly rising through the ranks due to her intelligence, tactical acumen, and magnetic personality. Initially, she preached freedom, equality, and justice — rallying the marginalized and oppressed with fiery speeches and acts of civil disobedience.

Her rise to power began when the revolution succeeded in overthrowing the old government, but cracks appeared as the new regime struggled to maintain order. Elara, consumed by the fear of losing everything she fought for, began demanding absolute loyalty and control. Paranoia creeped in — enemies lurked everywhere, traitors among friends — and in her bid to protect the “new society,” she began wielding power as ruthlessly as the tyrants she replaced.

Psyche and Motivations:

• Core motivation: Protecting the revolution’s ideals of equality and justice, but also an intense fear of failure and loss that twists into a need for control.
• Primary fear: Chaos and the revolution being undone by internal betrayal or external attack — stemming from childhood trauma of loss and powerlessness.
• Strengths:
  • Charismatic and inspiring — she can make crowds hang on her every word.
  • Brilliant strategist — able to out-think opponents and anticipate moves.
  • Deeply empathetic — once, she could feel the pain of the oppressed, but this fades as power hardens her.
• Weaknesses:
  • Growing paranoia — distrusts even her closest allies.
  • Ruthlessness — justifies cruelty in the name of “the greater good,” alienating those who once followed her.
  • Emotional isolation — suppresses vulnerability, leading to frequent internal conflict.
• Complexity: Elara isn’t evil for evil’s sake. She genuinely believes the ends justify the means and that any sacrifice is acceptable to prevent the chaos that destroyed her childhood.

Emotional Arc:

• Beginning: Idealistic and hopeful, Elara radiates passion and promises a better future. She is a symbol of hope.
• Middle: After attaining power, cracks appear. She grows suspicious, alienates mentors and friends, and begins using oppressive methods to preserve her vision.
• Climax: Her transformation into a dictator is complete when she orders the suppression or assassination of dissenters who once looked to her as a savior.
• Ending: A pivotal confrontation forces Elara to face the monster she’s become — possibly a moment of redemption or tragic downfall.

How She Resonates with Readers:

• Relatable motivations: Her fear of loss and desire to protect something precious mirrors universal human struggles.
• Morally grey: Readers sympathize with her early ideals and understand how trauma and fear can corrupt.
• Tragic figure: Elara embodies the danger of absolute power and the thin line between heroism and tyranny.
• Dialogue and voice: Her speeches are electrifying, full of passion and conviction — capable of inspiring both hope and dread.

Integration with Story Narrative:

Elara’s arc serves as a cautionary tale about revolutions and power, forcing the protagonist and readers to ask: What is worth fighting for? and Can one remain pure in a broken world? Her presence creates tension, depth, and a mirror for the protagonist’s own choices.

Would you like me to develop supporting characters or help plot key encounters with Elara?

  • Point-in-time backups on RDS daily + transaction logging for PITR
  • Regular S3 backups (cross-region replication for samples/media)
  • DR drills semi-annually to validate recovery process

• Backup Policies:

  • Incremental backups (RDS snapshot retention policy)
  • Immutable backups stored in separate regions

7. Security & Compliance

• Authentication/Authorization:

  • OAuth2 with JWT tokens (access + refresh tokens)
  • Fine-grained RBAC for creators, buyers, admins (e.g., creators see own private prompts)
  • SSO integration later (e.g., via Auth0 or AWS Cognito)

• Data Privacy Compliance:

  • GDPR compliance: users can request data export/deletion
  • Secure consent and cookie management
  • PCI-DSS compliance handled by payment gateways (Stripe/Paypal) — do not store card data

• Threat Mitigation:

  • WAF (AWS WAF) to fend off injection & common OWASP threats
  • Input validation & sanitization to prevent XSS, SQL Injection
  • DDoS protection (AWS Shield Advanced or Cloudflare in front)
  • Rate limiting at API Gateway
  • Secure CORS policies & Content Security Policy headers

8. DevOps & CI/CD Pipeline

• Deployment Model:

  • Containerize all services with Docker
  • Deploy on Kubernetes (AWS EKS) with Helm charts or Terraform for infra-as-code
  • Use namespaces for dev, staging, production environments

• CI/CD Tools:

  • GitHub Actions or GitLab CI for automated build/test/deploy pipelines
  • Pipelines run unit tests → integration tests → deploy to staging → manual or automatic deploy to prod

• Testing Strategy:

  • Unit tests at module level (Jest/Mocha for backend, React Testing Library for frontend)
  • Integration tests using Postman/Newman or Cypress
  • Load testing with k6 or Locust focused on payment & run counting paths

9. Scaling Roadmap

10. Key Trade-offs & Alternatives

• Flexibility vs Performance:

  • GraphQL offers client flexibility but can add complexity and query performance overhead → Cache aggressively or implement persisted queries
  • Strong consistency (PostgreSQL) vs faster flexible schema (NoSQL) → Use polyglot persistence for different workloads

• Alternative Tech Choices:

  • If budget constrained, use managed serverless (AWS Lambda + DynamoDB) to reduce ops but increase cold start latency and complexity
  • If small team, choose monolith or modular monolith in NodeJS for faster development vs full microservices from the start
  • Use Firebase for Auth and Realtime DB/Firestore as database alternative for MVP if time-to-market is crucial but limits flexibility

Summary

BetterPrompt will benefit from a microservices-based cloud architecture hosted on AWS, delivering secure, scalable, and reliable prompt marketplace experience. By combining RDBMS for core data, NoSQL for community/social features, and cloud storage/CDN for media, the system balances flexibility and performance, while a mature CI/CD pipeline and observability stack facilitate rapid iterative improvements.
