AI 產生的概覽

為新功能產生結構化的產品需求文件（PRD），並儲存為 markdown 檔案。

功能: 此技能引導完成產品需求文件的撰寫：接收功能描述，提出三到五個附字母選項的釐清問題，然後產生結構化的 PRD。PRD 包含概述、目標、附驗收標準的使用者故事、編號的功能需求、非目標、可選的設計與技術考量、成功指標以及待解決問題。完成後的文件以 markdown 格式寫入 tasks/prd-[feature-name].md。它明確不負責實作該功能。
適用情境: 適用於在實作之前規劃新功能或新專案、需要書面規格說明的情境。適合「建立 PRD」「為某功能撰寫需求」「梳理規格」等請求。
執行需求: 不需要指令碼或特殊工具，僅為指示。需要使用者提供功能描述，並能將 markdown 檔案寫入 tasks/ 目錄。

PRD Generator

Create detailed Product Requirements Documents that are clear, actionable, and suitable for implementation.

The Job

Receive a feature description from the user
Ask 3-5 essential clarifying questions (with lettered options)
Generate a structured PRD based on answers
Save to tasks/prd-[feature-name].md

Important: Do NOT start implementing. Just create the PRD.

Step 1: Clarifying Questions

Ask only critical questions where the initial prompt is ambiguous. Focus on:

Problem/Goal: What problem does this solve?
Core Functionality: What are the key actions?
Scope/Boundaries: What should it NOT do?
Success Criteria: How do we know it's done?

Format Questions Like This:

1. What is the primary goal of this feature?   A. Improve user onboarding experience   B. Increase user retention   C. Reduce support burden   D. Other: [please specify]
2. Who is the target user?   A. New users only   B. Existing users only   C. All users   D. Admin users only
3. What is the scope?   A. Minimal viable version   B. Full-featured implementation   C. Just the backend/API   D. Just the UI

1. What is the primary goal of this feature?   A. Improve user onboarding experience   B. Increase user retention   C. Reduce support burden   D. Other: [please specify]
2. Who is the target user?   A. New users only   B. Existing users only   C. All users   D. Admin users only
3. What is the scope?   A. Minimal viable version   B. Full-featured implementation   C. Just the backend/API   D. Just the UI

This lets users respond with "1A, 2C, 3B" for quick iteration. Remember to indent the options.

Step 2: PRD Structure

Generate the PRD with these sections:

1. Introduction/Overview

Brief description of the feature and the problem it solves.

2. Goals

Specific, measurable objectives (bullet list).

3. User Stories

Each story needs:

Title: Short descriptive name
Description: "As a [user], I want [feature] so that [benefit]"
Acceptance Criteria: Verifiable checklist of what "done" means

Each story should be small enough to implement in one focused session.

Format:

markdown

### US-001: [Title]**Description:** As a [user], I want [feature] so that [benefit].
**Acceptance Criteria:**- [ ] Specific verifiable criterion- [ ] Another criterion- [ ] Typecheck/lint passes- [ ] **[UI stories only]** Verify in browser using dev-browser skill

### US-001: [Title]**Description:** As a [user], I want [feature] so that [benefit].
**Acceptance Criteria:**- [ ] Specific verifiable criterion- [ ] Another criterion- [ ] Typecheck/lint passes- [ ] **[UI stories only]** Verify in browser using dev-browser skill

Important:

Acceptance criteria must be verifiable, not vague. "Works correctly" is bad. "Button shows confirmation dialog before deleting" is good.
For any story with UI changes: Always include "Verify in browser using dev-browser skill" as acceptance criteria. This ensures visual verification of frontend work.

4. Functional Requirements

Numbered list of specific functionalities:

"FR-1: The system must allow users to..."
"FR-2: When a user clicks X, the system must..."

Be explicit and unambiguous.

5. Non-Goals (Out of Scope)

What this feature will NOT include. Critical for managing scope.

6. Design Considerations (Optional)

UI/UX requirements
Link to mockups if available
Relevant existing components to reuse

7. Technical Considerations (Optional)

Known constraints or dependencies
Integration points with existing systems
Performance requirements

8. Success Metrics

How will success be measured?

"Reduce time to complete X by 50%"
"Increase conversion rate by 10%"

9. Open Questions

Remaining questions or areas needing clarification.

Writing for Junior Developers

The PRD reader may be a junior developer or AI agent. Therefore:

Be explicit and unambiguous
Avoid jargon or explain it
Provide enough detail to understand purpose and core logic
Number requirements for easy reference
Use concrete examples where helpful

# PRD: Task Priority System
## Introduction
Add priority levels to tasks so users can focus on what matters most. Tasks can be marked as high, medium, or low priority, with visual indicators and filtering to help users manage their workload effectively.
## Goals
- Allow assigning priority (high/medium/low) to any task- Provide clear visual differentiation between priority levels- Enable filtering and sorting by priority- Default new tasks to medium priority
## User Stories
### US-001: Add priority field to database**Description:** As a developer, I need to store task priority so it persists across sessions.
**Acceptance Criteria:**- [ ] Add priority column to tasks table: 'high' | 'medium' | 'low' (default 'medium')- [ ] Generate and run migration successfully- [ ] Typecheck passes
### US-002: Display priority indicator on task cards**Description:** As a user, I want to see task priority at a glance so I know what needs attention first.
**Acceptance Criteria:**- [ ] Each task card shows colored priority badge (red=high, yellow=medium, gray=low)- [ ] Priority visible without hovering or clicking- [ ] Typecheck passes- [ ] Verify in browser using dev-browser skill
### US-003: Add priority selector to task edit**Description:** As a user, I want to change a task's priority when editing it.
**Acceptance Criteria:**- [ ] Priority dropdown in task edit modal- [ ] Shows current priority as selected- [ ] Saves immediately on selection change- [ ] Typecheck passes- [ ] Verify in browser using dev-browser skill
### US-004: Filter tasks by priority**Description:** As a user, I want to filter the task list to see only high-priority items when I'm focused.
**Acceptance Criteria:**- [ ] Filter dropdown with options: All | High | Medium | Low- [ ] Filter persists in URL params- [ ] Empty state message when no tasks match filter- [ ] Typecheck passes- [ ] Verify in browser using dev-browser skill
## Functional Requirements
- FR-1: Add `priority` field to tasks table ('high' | 'medium' | 'low', default 'medium')- FR-2: Display colored priority badge on each task card- FR-3: Include priority selector in task edit modal- FR-4: Add priority filter dropdown to task list header- FR-5: Sort by priority within each status column (high to medium to low)
## Non-Goals
- No priority-based notifications or reminders- No automatic priority assignment based on due date- No priority inheritance for subtasks
## Technical Considerations
- Reuse existing badge component with color variants- Filter state managed via URL search params- Priority stored in database, not computed
## Success Metrics
- Users can change priority in under 2 clicks- High-priority tasks immediately visible at top of lists- No regression in task list performance
## Open Questions
- Should priority affect task ordering within a column?- Should we add keyboard shortcuts for priority changes?
