| Generic | AGENTS.md |
✅ Recommended Instruction
## IDE Integration
Always use the `jetbrains-index` MCP server when applicable for:
- **Finding references** — Use `ide_find_references` instead of grep/search
- **Go to definition** — Use `ide_find_definition` for accurate navigation
- **Renaming symbols** — Use `ide_refactor_rename` for safe, project-wide renames
- **Type hierarchy** — Use `ide_type_hierarchy` to understand class relationships
- **Finding implementations** — Use `ide_find_implementations` for interfaces/abstract classes
- **Diagnostics** — Use `ide_diagnostics` to check for code problems
The IDE's semantic understanding is far more accurate than text-based search.
Prefer IDE tools over grep, ripgrep, or manual file searching when working with code symbols.
🎯 Why Add Agent Instructions?
- Accuracy — IDE tools understand code semantics, not just text patterns
- Speed — Indexed lookups are instant, even in massive codebases
- Safety — Refactoring tools update all references automatically
- Completeness — Never miss a usage hidden in a complex expression
Without these instructions, your AI may fall back to text search and miss powerful IDE capabilities.
🔌 Verifying the Connection
Ask your AI assistant:
What tools do you have available from jetbrains-index?
You should see 10+ IDE-powered tools, including:
ide_find_referenceside_find_definitionide_refactor_renameide_type_hierarchyide_call_hierarchyide_find_implementationside_find_symbolide_diagnostics- …and more!
💡 Example Usage
🔄 Safe Rename Across Project
User: Rename the `getUserData` method to `fetchUserProfile` across the project
AI: I'll use the IDE's refactoring capability for a safe rename.
[Calls ide_refactor_rename]
✅ Renamed `getUserData` to `fetchUserProfile`
in 47 locations across 12 files.
🔍 Find Interface Implementations
User: Find all implementations of the PaymentProcessor interface
AI: Let me query the IDE's type index.
[Calls ide_find_implementations]
Found 4 implementations:
- StripePaymentProcessor (src/payments/stripe.kt:15)
- PayPalPaymentProcessor (src/payments/paypal.kt:22)
- MockPaymentProcessor (src/test/mocks/payments.kt:8)
- OfflinePaymentProcessor (src/payments/offline.kt:31)
🛠 Troubleshooting
❌ Connection Issues
- Ensure the IDE is running and a project is open
- Check the server URL in the tool window
(default port:63342) - Verify your AI client configuration matches the displayed URL
- For Claude Code: click “Install Now” again to refresh the connection
⚠️ Tools Not Appearing?
- Wait for IDE indexing to complete (check status bar)
- Restart your AI assistant after adding the MCP configuration
- Check the Command History tab in the tool window for activity
