🔧 Available Tools

📚 Wiki Tools (NEW - Optimized!)

list_wiki_pages -

List all wiki pages by name - perfect for exploration

• Use case: "What wiki pages do we have?"
• Speed: Very fast (metadata only)

search_wiki_pages -

Search wiki pages by name/path - no content fetching

• Use case: "Find pages about authentication"
• Speed: Very fast (searches names only)

get_wiki_page -

Get specific wiki page content when you know what you want

• Use case: "Get the API documentation page"
• Speed: Moderate (fetches one page)

get_wiki_section -

Extract specific sections from wiki pages

• Use case: "Get the installation section from setup docs"
• Speed: Moderate (fetches one page, extracts section)

search_wiki_content -

Search through actual page content - use sparingly

• Use case: "Find all mentions of 'database connection' in content"
• Speed: Slower (fetches and searches all content)

🧪 Test Plan Tools

• search_test_plans: Find test plans by name or description
• get_test_plan_details: Get detailed test plan information
• find_test_cases: Search test cases within plans or suites

📝 Work Item Tools

• search_work_items: Search work items with text queries

🔗 Cross-Reference Tools

• find_related_items: Find all related artifacts for a topic
• search_by_feature: Search by feature across all artifact types

💡 Usage Examples & Best Practices

🎯 Efficient Wiki Search Strategy

Step 1: Start with fast page search

"List all wiki pages in the codeless project"
→ Uses list_wiki_pages (very fast)

Step 2: Search by page names first

"Find wiki pages about API or authentication in codeless project"
→ Uses search_wiki_pages (fast - searches page names only)

Step 3: Get specific content when needed

"Get the content of the API Setup page"
→ Uses get_wiki_page (fetches specific page content)

Step 4: Only search content when necessary

"Search for 'database connection string' in all wiki content"
→ Uses search_wiki_content (slower - searches all page content)

💬 Natural Language Examples

Fast Operations:

• "What wiki pages do we have in the "acme" project?"
• "Find pages with 'setup' or 'install' in the name"
• "List all test plans for user authentication"

Moderate Operations:

• "Show me the API documentation page content"
• "Get the troubleshooting section from the setup guide"
• "Find test cases in the login test plan"

Slower Operations (use when needed):

• "Search all wiki content for mentions of database configuration"
• "Find all artifacts related to the payment processing feature"

⚡ Performance Optimizations

Wiki Performance Strategy

1. Metadata First: Always get page lists before content
2. Smart Caching: Pages cached for 5 minutes by default
3. Batch Processing: Content searches processed in batches
4. Retry Logic: Automatic retry with exponential backoff
5. Configurable Timeouts: Adjust AZDO_HTTP_TIMEOUT for large projects

For Large Projects

# Increase timeout for projects with many wiki pages
AZDO_HTTP_TIMEOUT=600000  # 10 minutes

# Adjust cache timeout if needed
AZDO_CACHE_TIMEOUT=900000  # 15 minutes

🚨 Troubleshooting

Common Issues

1. No Wiki Pages Found:

   • Verify project name is correct
   • Check PAT permissions include Wiki read access
   • Try: "List all wiki pages in [exact-project-name]"

2. Timeout Errors:

   • Increase AZDO_HTTP_TIMEOUT environment variable
   • For very large projects: set to 600000 (10 minutes)

3. Empty Search Results:

   • Try list_wiki_pages first to see available pages
   • Use search_wiki_pages for name-based search
   • Only use search_wiki_content for content search

Debug Commands

Test your connection:

# Test basic connectivity
echo '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}' | node index.js

# Test wiki listing
echo '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"list_wiki_pages","arguments":{"project":"YourProject"}}}' | node index.js
