JetBrains Integration
Using Claude Code in JetBrains IDEs. This guide provides complete code examples and terminal operation demos.
Quick Start
Launch Claude Code in the terminal:
bash
claude
You: Help me implement using Claude Code in JetBrains IDE
Claude: Sure, let me first look at the project structure...
Claude wants to:
• Read file: src/main.py
Allow? [y/n/always/never]
You: y
Claude: Let me implement this feature for you...Press Shift+Tab to cycle through permission modes:
bash
# Normal Mode → Auto-Accept Mode → Plan Mode
# Auto-Accept: Auto-execute (bottom shows ⏵⏵ accept edits on)
You: Quick implementation
Claude: [Auto-executes without confirmation]
# Plan Mode: Read-only (bottom shows ⏸ plan mode on)
You: Create a plan first
Claude: [Only creates a plan, does not execute]Basic Concepts
bash
You: Explain the core concepts of JetBrains integration
Claude: The core concepts of using Claude Code in JetBrains IDE include...python
from anthropic import Anthropic
client = Anthropic()
response = client.messages.create(
model="claude-sonnet-4-6",
max_tokens=1024,
messages=[{"role": "user", "content": "Using Claude Code in JetBrains IDE"}]
)
print(response.content[0].text)Implementation Steps
1. Environment Setup
bash
# Install dependencies
pip install anthropic
# Configure API Key
export ANTHROPIC_API_KEY="your-api-key"2. Core Implementation
bash
You: Help me implement the core functionality of JetBrains integration
Claude: Sure, let me create the implementation file...
Claude wants to:
• Write file: src/jetbrains_integration.py
Allow? [y/n/always/never]
You: y
Claude: File created.python
# JetBrains Integration Core Implementation
from anthropic import Anthropic
client = Anthropic()
def process(query: str) -> str:
"""Process user request"""
response = client.messages.create(
model="claude-sonnet-4-6",
max_tokens=2048,
messages=[{"role": "user", "content": query}]
)
return response.content[0].text
if __name__ == "__main__":
result = process("Using Claude Code in JetBrains IDE")
print(result)3. Test Verification
bash
You: Run tests to verify the implementation
Claude: Sure, let me run the tests...
Claude wants to:
• Run command: python -m pytest tests/
Allow? [y/n/always/never]
You: y
Claude: All tests passed ✅Advanced Usage
python
# Using streaming output
with client.messages.stream(
model="claude-sonnet-4-6",
max_tokens=2048,
messages=[{"role": "user", "content": "Using Claude Code in JetBrains IDE"}]
) as stream:
for text in stream.text_stream:
print(text, end="", flush=True)bash
# Using tool calls
tools = [{
"name": "process",
"description": "Using Claude Code in JetBrains IDE",
"input_schema": {
"type": "object",
"properties": {
"query": {"type": "string"}
},
"required": ["query"]
}
}]
response = client.messages.create(
model="claude-sonnet-4-6",
max_tokens=1024,
tools=tools,
messages=[{"role": "user", "content": "Using Claude Code in JetBrains IDE"}]
)Performance Optimization
python
# Use Prompt Caching to reduce costs
response = client.messages.create(
model="claude-sonnet-4-6",
max_tokens=1024,
system=[{
"type": "text",
"text": "You are an expert in using Claude Code in JetBrains IDE...",
"cache_control": {"type": "ephemeral"}
}],
messages=[...]
)bash
# View cost
/cost
# Switch to a faster model
/model haiku
# Use fast mode
/fastError Handling
python
from anthropic import APIError, APITimeoutError
try:
response = client.messages.create(
model="claude-sonnet-4-6",
max_tokens=1024,
messages=[{"role": "user", "content": "request"}]
)
except APITimeoutError:
print("Request timed out, please retry")
except APIError as e:
print(f"API error: {e.status_code} - {e.message}")Best Practices
- Clear task descriptions - Tell Claude exactly what to do
- Provide context - Use CLAUDE.md or provide relevant code directly
- Verify step by step - Validate results after each step
- Use Plan Mode - Create a plan first for complex tasks
- Monitor costs - Use
/costto check API usage - Choose models wisely - Use Haiku for simple tasks, Opus for complex ones
Permission Modes Reference
| Mode | Shortcut | Bottom Display | Behavior |
|---|---|---|---|
| Normal | Default | No indicator | Each operation requires confirmation |
| Auto-Accept | Shift+Tab ×1 | ⏵⏵ accept edits on | Auto-execute edits |
| Plan | Shift+Tab ×2 | ⏸ plan mode on | Only create plans |
Common Commands Reference
bash
/help # View help
/clear # Clear history
/model opus # Switch to Opus 4.6
/model sonnet # Switch to Sonnet 4.6
/model haiku # Switch to Haiku 4.5
/cost # View cost
/fast # Fast mode
/quit # Exit
