Scratches pro Claude Workflows

JetBrains Scratches jsou perfektní pro Claude interakci:

# Scratches/claude-workspace.py

from anthropic import Anthropic

client = Anthropic()

# Paste code here
CODE = """
def mystery_function(data):
    result = []
    seen = set()
    for item in data:
        key = item.get('id')
        if key not in seen:
            seen.add(key)
            result.append(item)
    return result
"""

response = client.messages.create(
    model="claude-opus-4-5-20250101",
    max_tokens=2000,
    messages=[{
        "role": "user",
        "content": f"Explain what this function does:\n\n{CODE}"
    }]
)

print(response.content[0].text)

Database Tool Integration

Pro práci s databázemi v DataGrip/IntelliJ:

# scripts/explain-query.py
import sys
from anthropic import Anthropic

query = sys.argv[1]

client = Anthropic()
response = client.messages.create(
    model="claude-opus-4-5-20250101",
    max_tokens=2000,
    messages=[{
        "role": "user",
        "content": f"""Explain this SQL query:

```sql
{query}

Include:

1. What it does
2. Performance considerations
3. Potential optimizations""" }] )

print(response.content[0].text)

External Tool:

Name: Explain SQL Program: python3 Arguments: $ProjectFileDir$/scripts/explain-query.py “$SelectedText$“

## Run Configuration pro Claude Scripts

```xml
<!-- .idea/runConfigurations/Claude_Review.xml -->
<component name="ProjectRunConfigurationManager">
  <configuration name="Claude Review" type="PythonConfigurationType">
    <module name="your-project" />
    <option name="SCRIPT_NAME" value="$PROJECT_DIR$/scripts/claude-review.py" />
    <option name="PARAMETERS" value="$FilePath$" />
    <option name="WORKING_DIRECTORY" value="$PROJECT_DIR$" />
  </configuration>
</component>

Plugin Development (Advanced)

Pro hlubší integraci můžete vytvořit vlastní plugin:

// src/main/kotlin/ClaudeAction.kt
class AskClaudeAction : AnAction() {
    override fun actionPerformed(e: AnActionEvent) {
        val editor = e.getData(CommonDataKeys.EDITOR) ?: return
        val selectedText = editor.selectionModel.selectedText ?: return
        
        // Call Claude API
        val response = ClaudeService.ask(selectedText)
        
        // Show in tool window
        ClaudeToolWindow.show(response)
    }
}

Workflow příklad

Refactoring session

1. Identifikace - Vyberte code smell v IDE
2. Analýza - Ctrl+Shift+C → Claude vysvětlí problém
3. Plán - Claude navrhne refactoring strategii
4. Implementace - Použijte IDE refactoring tools
5. Review - Claude zkontroluje výsledek

IDE:     [Identify] → [Implement] → [Test]
              ↓            ↑           ↓
Claude:  [Analyze] → [Plan] → [Review]

Kombinace JetBrains IDE s Claude vám dává to nejlepší z obou světů.
