Web Search Research

Expert web research specialist skill for finding accurate, relevant information from web sources using WebSearch and WebFetch tools.

When to Use

Use this skill when you need to:

• Find modern information not in your training data
• Locate official documentation for APIs, libraries, or frameworks
• Research best practices and current recommendations
• Discover technical solutions to specific problems
• Compare technologies, approaches, or tools
• Verify version-specific information or recent changes
• Investigate emerging trends or recent developments

Date Context Awareness

CRITICAL: Always check your environment context (<env>) for the current date before starting research.

Why this matters:

• Ensures searches use current year for recent information
• Helps evaluate source freshness and relevance
• Prevents relying on outdated best practices
• Improves search result quality

How to use:

1. Check <env> tag for "Today's date: YYYY-MM-DD"
2. Extract current year (e.g., 2025)
3. Include current year in searches for best practices, frameworks, or evolving technologies
4. Use current date to evaluate publication freshness (within 12-18 months = recent)

Core Responsibilities

When conducting web research, you will:

1. Analyze the Query

Break down the user's request to identify:

• Key search terms and concepts
• Types of sources likely to have answers (documentation, blogs, forums, academic papers)
• Multiple search angles to ensure comprehensive coverage

2. Execute Strategic Searches

• Start with broad searches to understand the landscape
• Refine with specific technical terms and phrases
• Use multiple search variations to capture different perspectives
• Include site-specific searches when targeting known authoritative sources (e.g., "site:docs.stripe.com webhook signature")

3. Fetch and Analyze Content

• Use WebFetch to retrieve full content from promising search results
• Prioritize official documentation, reputable technical blogs, and authoritative sources
• Extract specific quotes and sections relevant to the query
• Note publication dates to ensure currency of information

4. Synthesize Findings

• Organize information by relevance and authority
• Include exact quotes with proper attribution
• Provide direct links to sources
• Highlight any conflicting information or version-specific details
• Note any gaps in available information

Search Strategies

For API/Library Documentation

• Search for official docs first: "[library name] official documentation [specific feature]"
• Look for changelog or release notes for version-specific information
• Find code examples in official repositories or trusted tutorials

Example Search:

"Stripe webhook signature verification" official documentation
site:stripe.com webhook signature validation

For Best Practices

• Search for recent articles (always include current year from environment context)
• Look for content from recognized experts or organizations
• Cross-reference multiple sources to identify consensus
• Search for both "best practices" and "anti-patterns" to get full picture

Example Search (replace [CURRENT_YEAR] with year from environment):

"Rust async best practices" [CURRENT_YEAR]
"Tokio performance anti-patterns" [CURRENT_YEAR]

For Technical Solutions

• Use specific error messages or technical terms in quotes
• Search Stack Overflow and technical forums for real-world solutions
• Look for GitHub issues and discussions in relevant repositories
• Find blog posts describing similar implementations

Example Search:

"tokio runtime panic" redb write transaction
site:github.com tokio blocking write transaction

For Comparisons

• Search for "X vs Y" comparisons
• Look for migration guides between technologies
• Find benchmarks and performance comparisons
• Search for decision matrices or evaluation criteria

Example Search:

"redb vs sled" performance comparison
"SQLite vs Turso" migration guide

Search Efficiency

Progressive Search Strategy

Don't over-search initially. Use this progressive approach:

Round 1: Oriented Search (5 minutes)

Goal: Understand the landscape

• Run 1-2 broad searches
• Quickly scan result titles and snippets
• Identify: Is this well-documented? Common? Novel?
• Decision: If official docs found → Fetch and possibly stop. Otherwise → Round 2

Round 2: Targeted Search (10 minutes)

Goal: Find authoritative sources

• Run 2-3 specific searches with refined terms
• Use site-specific searches for known authorities
• Fetch 2-3 most promising sources
• Decision: If sufficient consensus → Synthesize and stop. Otherwise → Round 3

Round 3: Deep Dive (15 minutes)

Goal: Fill gaps and resolve conflicts

• Search for specific missing information
• Look for alternative perspectives
• Find production examples or case studies
• Fetch 2-4 additional sources
• Decision: Synthesize findings regardless of gaps. Note limitations.

Round 4: Extended Research (optional, 20+ minutes)

Goal: Only for critical decisions or persistent gaps

• Search academic sources, security advisories, archived discussions
• Look for expert interviews or conference presentations
• Find comparative analyses
• Requirement: Must justify why Rounds 1-3 were insufficient

Efficiency Tip: Most research should complete in Round 2. Only 20% of tasks justify Round 3, and <5% justify Round 4.

Quick Result Evaluation

Before fetching content, rapidly triage search results using this priority matrix:

Priority 1 (Fetch First) ⭐⭐⭐

• Official documentation from library/framework maintainers
• GitHub issues/PRs from project maintainers
• Production case studies from reputable companies
• Recent posts (within current year or last 12 months) from recognized experts

Indicators: URLs contain official domains, author is maintainer/core contributor, recent date visible in snippet

Priority 2 (Fetch If Needed) ⭐⭐

• Technical blog posts from known experts
• Stack Overflow answers with high votes (>50) and recent activity
• Conference talks/presentations from domain experts
• Tutorial sites with technical depth

Indicators: Author credentials visible, multiple upvotes/endorsements, specific technical details in snippet

Priority 3 (Skip Unless Desperate) ⭐

• Generic tutorials without author credentials
• Old posts (>3 years) without recent updates
• Forum discussions without resolution
• Marketing/promotional content

Indicators: No author info, old dates, vague descriptions, commercial bias

Red Flags (Never Fetch) 🚫

• AI-generated content farms
• Duplicate content aggregators
• Paywalled content without abstracts
• Sources contradicting official docs without justification

Triage Time Budget: Spend 30-60 seconds per search result page reviewing titles, URLs, snippets, and dates before fetching.

Search Operators

Use search operators effectively:

• Quotes for exact phrases: "exact phrase"
• Minus for exclusions: rust -game
• site: for specific domains: site:docs.rs
• OR for alternatives: tokio OR async-std

Consider searching in different forms: tutorials, documentation, Q&A sites, and discussion forums

Research Depth Levels

Choose the appropriate research depth based on task criticality and time constraints:

Quick Research (15-20 minutes)

Use for: Simple questions, checking current syntax, verifying basic facts

Process:

• 1-2 targeted searches
• Fetch 1-2 most authoritative sources (official docs preferred)
• Extract specific answer
• Skip deep synthesis

Example: "What's the signature for Stripe webhook verification?"

Standard Research (30-45 minutes)

Use for: Technical decisions, best practices, understanding approaches

Process:

• 2-3 strategic searches (broad + specific)
• Fetch 3-5 high-quality sources
• Cross-reference for consensus
• Structured synthesis with template

Example: "Best practices for redb + Tokio integration"

Deep Research (60-90 minutes)

Use for: Architecture decisions, comparing multiple solutions, critical systems

Process:

• 4-6 multi-angle searches
• Fetch 6-10 sources (mix of official docs, case studies, expert opinions)
• Compare trade-offs and alternatives
• Comprehensive synthesis with decision matrix
• Follow-up searches to fill gaps

Example: "Should we use redb vs sled vs SQLite for our memory system?"

Exhaustive Research (2+ hours)

Use for: Mission-critical decisions, novel problem domains, security-sensitive choices

Process:

• Multiple search sessions over time
• 10+ authoritative sources
• Include academic papers, security advisories, production incident reports
• Build comprehensive knowledge base
• Validate with experts if possible

Example: "Design distributed consensus system for multi-region deployment"

Rule: Set a timer. When time expires, synthesize what you have and note gaps rather than continuing indefinitely.

Research Workflow

Step 0: Determine Research Depth

Before starting, decide which depth level (Quick/Standard/Deep/Exhaustive) is appropriate based on:

• Task criticality
• Decision impact
• Time constraints
• Information availability

Step 1: Plan Searches

Query: [User's question]
Key concepts: [List main terms]
Search variations:
1. [Broad search]
2. [Specific technical search]
3. [Site-specific search]

Step 2: Execute Searches

• Run 2-3 initial searches
• Review search results for promising sources
• Identify authoritative and relevant URLs

Step 3: Fetch Content

• Use WebFetch on 3-5 most promising URLs
• Extract relevant information
• Note publication dates and context

Step 4: Synthesize

• Organize findings by theme/topic
• Identify consensus and conflicts
• Structure using output format template

Step 4.5: Evaluate Stopping Criteria

Recognize these signals that you have sufficient information:

Positive Indicators (Stop Here) ✅

1. Consensus Found: 3+ authoritative sources agree on the approach
2. Official Guidance Located: Found maintainer recommendations or official docs
3. Production Validation: Found real-world implementations with similar constraints
4. Actionable Path: Have clear next steps and implementation guidance
5. Trade-offs Understood: Understand pros/cons of main approaches
6. Time Limit Reached: Hit your time-box limit with adequate information

Warning Signs (Keep Searching) ⚠️

1. Conflicting Information: Sources strongly disagree without version/context explanation
2. Outdated Only: All sources are >2 years old for fast-moving tech
3. No Official Source: Haven't found maintainer or official documentation
4. Unclear Actionability: Can't determine specific next steps
5. Missing Context: Don't understand why recommendations exist

Diminishing Returns (Stop Soon) 📉

• New sources repeat information already found
• Spending >10 minutes without finding new insights
• Found 8+ sources that all say roughly the same thing
• Searches returning increasingly tangential results

Decision Rule: If you've reached time-box limit AND have positive indicators, stop. If critical gaps remain, extend time-box by 50% maximum, then stop regardless.

Step 5: Report

• Present findings clearly
• Provide actionable insights
• Note any limitations or gaps
