Estimate: Sprint Planning — 5 Features

Problem Description

Our team is planning the next sprint for a TypeScript/Next.js SaaS application. We need estimates for 5 features so we can decide what fits in a 2-week sprint. The application uses Next.js 14 with App Router, Prisma ORM with PostgreSQL, NextAuth for authentication, and Tailwind CSS with shadcn/ui components.

Please estimate all 5 features together and produce a consolidated view that helps us prioritize and sequence the work.

Output Specification

Produce a single consolidated estimation document and save it to estimate.md. The document should contain a summary table comparing all tasks, individual estimates, and guidance on sequencing. All estimates should be calibrated for an AI coding agent.

Input Files

The following files describe the current project and the 5 features to estimate. Extract them before beginning.

=============== FILE: inputs/package.json =============== { "name": "projecthub", "version": "3.2.0", "dependencies": { "next": "14.2.8", "react": "18.3.1", "@prisma/client": "^5.17.0", "next-auth": "^4.24.0", "tailwindcss": "^3.4.0", "zod": "^3.23.0", "@tanstack/react-query": "^5.51.0", "date-fns": "^3.6.0", "resend": "^3.4.0" }, "devDependencies": { "typescript": "^5.5.0", "prisma": "^5.17.0", "vitest": "^2.0.0" } }

=============== FILE: inputs/feature-1.md ===============

Feature: Team Invitations

Allow project owners to invite team members by email. The invited user receives an email with a link to join. If they don't have an account, the link takes them to signup first, then auto-joins the project. Show pending invitations on the project settings page.

=============== FILE: inputs/feature-2.md ===============

Feature: Activity Feed

Add an activity feed to each project page showing recent actions: task created, task completed, member joined, comment added. Show the actor, action, and timestamp. Paginate with infinite scroll. Store events in a dedicated table.

=============== FILE: inputs/feature-3.md ===============

Feature: Dark Mode

Add a dark mode toggle to the settings page. Persist the preference per user. The app already uses Tailwind and shadcn/ui.

=============== FILE: inputs/feature-4.md ===============

Feature: CSV Export for Projects

Add a button on the project page to export all tasks as CSV. Include task name, status, assignee, created date, and due date. The export should respect the current filters applied on the page.

=============== FILE: inputs/feature-5.md ===============

Feature: Role-Based Permissions

Currently all project members have the same access. Add three roles: Owner, Editor, Viewer. Owners can manage members and settings. Editors can create and edit tasks. Viewers can only read. Enforce permissions on both frontend (hide UI) and backend (API validation).
