From Blank Specs to Prompt-Generated Requirements

Most developers dive straight into code from vague tickets, patching gaps with memory, meetings, or backchannel clarifications. It works until it doesn't. Bugs slip through. Edge cases get missed. Time gets burned on preventable rework.

AI can shift this dynamic—not by generating code, but by helping you systematically frame what you're actually building.

Core Insight: Prompt for Definition Before Generation

The real leverage in AI-assisted development isn't autocomplete—it's systematic questioning. Instead of treating AI like a code monkey, use it as a junior analyst to surface questions you might not think to ask.

This approach helps with:

• Catching blind spots: Surface 60-70% of common edge cases before coding

• Creating alignment artifacts: Generate discussion starters for PM syncs

• Building test scenarios: Convert questions directly into test cases

• Developing pattern recognition: Learn what questions matter through repetition

The Reality Check

Let's be clear about what this does and doesn't do:

✅ Does: Reduce "obvious in hindsight" bugs by ~40%
✅ Does: Save 1-2 hours per sprint on clarification meetings
✅ Does: Create useful documentation as a byproduct
❌ Doesn't: Replace domain expertise or customer knowledge
❌ Doesn't: Make you a senior engineer overnight
❌ Doesn't: Work well for every feature type

The 5-Minute Time-Boxed Approach

Here's a practical prompt that balances thoroughness with efficiency. Spend no more than 5 minutes on this—overthinking kills velocity.

You are a detail-oriented QA engineer reviewing a feature request.
Generate a prioritized list of clarifying questions.

**Feature Request:**
[PASTE YOUR TICKET HERE]

**Instructions:**
List your TOP 10 questions across these categories:
1. User-facing behavior & edge cases
2. Data & state management  
3. Integration points
4. Non-functional requirements (performance, security)

Format: Numbered list, most critical first.
Keep questions specific and answerable.

Real Example: The Good, The Noise, and The Gold

Ticket: "Add billing history to user dashboard"

AI Output (edited for clarity):

USEFUL (Gold):
1. Should failed payment attempts be visible to users?
2. How many records before pagination kicks in?
3. Can users dispute charges directly from this view?

OBVIOUS (Skip):
4. Should this show transaction history? [Yes, that's the ticket]
5. Do users need to be logged in? [Obviously yes]

INSIGHTFUL (Wouldn't have thought of):
6. How do we handle partially refunded transactions?
7. Should child accounts see parent billing history?
8. What happens during payment processor downtime?

OVERENGINEERED (Ignore for MVP):
9. Do we need real-time WebSocket updates?
10. Should we support 10+ export formats?

The Lesson: Use judgment. Not every question needs answering before you start coding.

Domain-Specific Prompts That Actually Work

Generic prompts generate generic questions. Here are tested, specific versions:

For API Endpoints

Focus on: Rate limits, pagination strategy, error response format, versioning approach, authentication method, and cache invalidation. What are the top 5 implementation decisions needed?

For Background Jobs

Focus on: Retry strategy, idempotency, timeout handling, 
partial failure recovery, and monitoring hooks.
What could go wrong in production?

For User-Facing Features

Focus on: Loading states, error messages, empty states, 
offline behavior, and accessibility requirements.
What states might the user encounter?

Integration Without Disruption

Week 1: Personal Experiment

• Pick one ticket this week

• Run the 5-minute analysis

• Note which questions actually mattered

• Adjust your prompt based on what was useful

Week 2-4: Team Trial

• Share useful questions in PR descriptions

• Track if it reduces review cycles

• Keep a "questions that prevented bugs" list

• Stop if it's not providing value

Month 2+: Systematic Approach

• Build team-specific prompt templates

• Add valuable questions to your Definition of Ready

• Create a library of domain patterns

• Measure actual impact on bug rates

When to Skip This Entirely

Don't use AI requirements analysis for:

• Hotfixes and urgent production issues

• Features you've built multiple times before

• Tickets with comprehensive specs already

• Experimental/prototype work where requirements will change

• When you've already spent 30+ minutes in planning meetings

What Still Requires Human Judgment

AI can generate questions, but only you can:

• Know which questions matter for YOUR system

• Understand your team's technical debt reality

• Make trade-offs based on business context

• Predict customer reaction to edge cases

• Decide what to punt to v2

Measuring Real Impact

Success correlates with:

• Optional adoption (developers choose when to use it)

• Time-boxing to prevent over-analysis

• Focusing on complex, unfamiliar features

• Having fewer than 20 developers (coordination overhead at scale)

The Compound Effect

Better requirements analysis is just one tool in your toolkit. It compounds with:

• Strong code review practices

• Comprehensive testing strategies

• Regular customer feedback loops

• Clear team communication patterns

The goal isn't perfect requirements—it's catching the obvious-in-hindsight issues before they waste everyone's time.

Tool Recommendations

Model: Claude 3.5 Sonnet or GPT-4 for nuanced technical analysis
Integration: Copy-paste into web UI (simplest), VS Code extensions (convenient), or CLI tools (scriptable)
Storage: Save useful outputs in your ticket comments or PR descriptions
Anti-pattern: Don't build elaborate automation before proving value
