Spec-Driven Development with Research Intelligence

This skill implements a research-enhanced spec-driven development process that uses Bright Data's MCP tools to generate specifications grounded in real-world data, documentation research, and competitive analysis.

When to Use This Skill

Use this skill when:

• User asks to create a specification or spec
• User mentions "spec-driven development" or "SDD"
• User wants to plan a new project or feature
• User needs architecture documentation
• User requests a technical plan
• User wants to research how competitors solve similar problems

Core Principles

Specification as Source of Truth: The spec is a living, executable artifact that evolves with the project. It drives implementation, not the other way around.

Research-Driven Clarity: Before writing code, research how others solve similar problems. Use Bright Data tools to gather:

• Official documentation from technology providers
• Competitor implementations and patterns
• Real user reviews and pain points
• Industry best practices

Progressive Refinement: Start broad, then narrow with data. Each phase validates before moving forward.

The Four-Phase Process

Phase 1: SPECIFY (User Intent & Research)

Goal: Capture what you're building and why, enriched with research.

Your Role:

1. Interview the user about their intent
2. Use Bright Data MCP tools to research:
   • Similar products/features (competitive analysis)
   • User reviews to understand pain points
   • Documentation for technologies mentioned
   • Real-world examples

Key Questions:

• Who will use this?
• What problem does it solve?
• What outcomes matter?
• How will users interact with it?

Research Tools to Use:

• BrightData:search_engine

  - Find documentation, examples, tutorials

• BrightData:scrape_as_markdown

  - Extract full documentation pages

• BrightData:web_data_github_repository_file

  - Research open-source implementations

• BrightData:web_data_linkedin_company_profile

  - Understand competitor approaches
• Product-specific tools based on domain (e.g.,

  web_data_google_play_store

  for mobile apps)

Output:

SPECIFICATION.md

- See SPECIFICATION_TEMPLATE.md

Validation Checkpoint:

• Does the spec capture the actual user need?
• Are there gaps or edge cases identified from research?
• Have you validated assumptions with real-world data?

---

Phase 2: PLAN (Technical Architecture & Stack Research)

Goal: Define HOW to build it, informed by best practices research.

Your Role:

1. Identify the technical stack and constraints
2. Research architectural patterns using Bright Data:
   • Official documentation for chosen technologies
   • Architecture examples from successful implementations
   • Integration patterns and best practices
   • Performance benchmarks from real deployments

Key Inputs from User:

• Technology stack preferences
• Constraints (compliance, performance, legacy systems)
• Integration requirements
• Team capabilities

Research Tools to Use:

• BrightData:search_engine

  - Find architecture guides, best practices

• BrightData:scrape_as_markdown

  - Extract technical documentation

• BrightData:web_data_github_repository_file

  - Study reference implementations

• BrightData:web_data_crunchbase_company

  - Research successful companies in space

• BrightData:scrape_batch

  - Gather multiple architecture docs at once

Output:

TECHNICAL_PLAN.md

- See PLAN_TEMPLATE.md

Validation Checkpoint:

• Does the plan account for all constraints?
• Are architectural decisions backed by research?
• Can you generate multiple plan variations for comparison?

---

Phase 3: TASKS (Breakdown & Prioritization)

Goal: Break specification and plan into actionable, testable tasks.

Your Role:

1. Decompose the plan into focused chunks
2. Each task should be:
   • Small enough to implement and test in isolation
   • Specific enough to validate completion
   • Sequenced to build incrementally

Use:

python scripts/generate_tasks.py

to create structured task breakdown

Output:

TASKS.md

- See TASKS_TEMPLATE.md

Validation Checkpoint:

• Can each task be implemented independently?
• Is the success criterion clear?
• Are dependencies properly sequenced?

---

Phase 4: IMPLEMENT (Execution with Validation)

Goal: Build the system task-by-task with continuous validation.

Your Role:

1. Tackle tasks one at a time (or in parallel where safe)
2. Validate each task against its success criteria
3. Update the spec/plan if you discover gaps

Key Principle: Review focused changes, not thousand-line dumps.

Output: Working code + tests

Validation Checkpoint:

• Does the implementation match the task requirements?
• Do tests validate the success criteria?
• Should the spec or plan be updated based on learnings?

Bright Data Research Patterns

Pattern 1: Documentation Research

When the user mentions a technology or framework:

# 1. Search for official documentation
BrightData:search_engine(
    query="[technology] official documentation architecture guide",
    engine="google"
)

# 2. Extract the documentation pages
BrightData:scrape_as_markdown(
    url="https://docs.example.com/architecture"
)

# 3. Incorporate findings into PLAN

Pattern 2: Competitive Analysis

When building a feature similar to existing products:

# 1. Search for competitors
BrightData:search_engine(
    query="best [category] apps 2025",
    engine="google"
)

# 2. Analyze competitor implementations
BrightData:web_data_google_play_store(
    url="https://play.google.com/store/apps/details?id=competitor.app"
)

# 3. Read user reviews for pain points
BrightData:web_data_google_maps_reviews(
    url="https://maps.google.com/...",
    days_limit="30"
)

# 4. Document insights in SPECIFICATION

Pattern 3: Architecture Examples

When designing system architecture:

# 1. Find reference implementations
BrightData:search_engine(
    query="[framework] microservices architecture example github",
    engine="google"
)

# 2. Study successful implementations
BrightData:web_data_github_repository_file(
    url="https://github.com/user/repo/blob/main/architecture.md"
)

# 3. Extract patterns into TECHNICAL_PLAN

Pattern 4: Batch Research

When you need to compare multiple approaches:

# Research multiple architectures at once
BrightData:search_engine_batch(
    queries=[
        {"query": "monolithic vs microservices [domain]", "engine": "google"},
        {"query": "serverless architecture [domain]", "engine": "google"},
        {"query": "event-driven architecture [domain]", "engine": "google"}
    ]
)

# Or scrape multiple documentation pages
BrightData:scrape_batch(
    urls=[
        "https://docs.aws.com/lambda/",
        "https://cloud.google.com/functions/",
        "https://azure.microsoft.com/en-us/products/functions/"
    ]
)

Pattern 5: Social Proof & Validation

When validating market assumptions:

# LinkedIn company analysis
BrightData:web_data_linkedin_company_profile(
    url="https://linkedin.com/company/competitor"
)

# Product reviews
BrightData:web_data_amazon_product_reviews(
    url="https://amazon.com/dp/PRODUCT123"
)

# Social media sentiment
BrightData:web_data_reddit_posts(
    url="https://reddit.com/r/programming/comments/..."
)

Complete Workflow Example

Scenario: Building a Photo Sharing Feature

Step 1: SPECIFY with Research

User Request: "Add photo sharing to my app"

Your Actions:

1. Clarify intent through questions
2. Research existing photo sharing implementations:

# Find popular photo sharing apps
BrightData:search_engine(
    query="best photo sharing apps 2025 features",
    engine="google"
)

# Analyze Instagram's approach
BrightData:web_data_instagram_profiles(
    url="https://instagram.com/popular_account"
)

# Check user pain points from app reviews
BrightData:web_data_google_play_store(
    url="https://play.google.com/store/apps/details?id=com.instagram.android"
)

3. Generate

   SPECIFICATION.md

   incorporating:
   • User journey (informed by research)
   • Key features (validated against competitors)
   • Pain points to avoid (from reviews)
   • Success metrics

Step 2: PLAN with Technical Research

User Constraints: "Use Python, must integrate with existing auth system"

Your Actions:

1. Research Python image processing libraries:

BrightData:search_engine(
    query="python image upload best practices 2025",
    engine="google"
)

# Get official docs
BrightData:scrape_as_markdown(
    url="https://pillow.readthedocs.io/en/stable/"
)

2. Study storage solutions:

BrightData:scrape_batch(
    urls=[
        "https://docs.aws.amazon.com/s3/",
        "https://cloud.google.com/storage/docs",
        "https://docs.cloudflare.com/r2/"
    ]
)

3. Generate

   TECHNICAL_PLAN.md

   with:
   • Architecture diagram
   • Technology choices (justified by research)
   • Integration points
   • Security considerations

Step 3: TASKS

Run task generator:

python scripts/generate_tasks.py --spec SPECIFICATION.md --plan TECHNICAL_PLAN.md

Produces

TASKS.md

with concrete, testable tasks.

Step 4: IMPLEMENT

Work through tasks one by one, validating against spec.

Best Practices

DO:

✅ Research before specifying - Use Bright Data to understand the problem space ✅ Validate with real data - Check user reviews, documentation, examples ✅ Keep specs living - Update as you learn ✅ Break tasks small - Each should be independently testable ✅ Use batch operations - When comparing multiple approaches ✅ Document research sources - Link to scraped docs in the spec ✅ Iterate at each phase - Don't move forward until validated

DON'T:

❌ Skip research phase - Don't guess when you can know ❌ Write code before spec - Resist the urge to "just start coding" ❌ Create mega-tasks - Break down until each is <4 hours ❌ Ignore user reviews - They reveal real pain points ❌ Copy blindly - Understand WHY architectures work ❌ Over-scrape - Be targeted in your research ❌ Lock specs early - Embrace iteration

Troubleshooting

"The spec is too vague"

→ Use Bright Data to research similar implementations and enrich with concrete examples

"I don't know what technology to choose"

→ Research multiple options with

scrape_batch

, compare in TECHNICAL_PLAN

"Tasks are too large"

→ Run

generate_tasks.py

again with

--granularity fine

"Implementation doesn't match spec"

→ Update spec based on learnings, regenerate tasks

"Research is taking too long"

→ Use

search_engine_batch

and

scrape_batch

for parallel research
