Test-Guided Tool Run Skill

Before running any MCP tool directly (outside the MCP server), examine the corresponding integration test to understand the correct usage pattern.

Workflow

1. Find the Integration Test

python .claude/skills/test-guided-tool-run/scripts/find_test.py <tool_name>

Example:

python .claude/skills/test-guided-tool-run/scripts/find_test.py get_transaction_info

2. Read the Integration Test

The script outputs the test file path. Read it to understand:

• Import statements and mock context setup
• Real test data (addresses, transaction hashes, etc.)
• Expected response structure

3. Create Your Test Script

Use this template in /tmp/claude/.../scratchpad/:

#!/usr/bin/env python3
import asyncio
import sys
from pathlib import Path
from unittest.mock import AsyncMock, MagicMock

sys.path.insert(0, str(Path(__file__).parent.parent.parent.parent.parent))

from blockscout_mcp_server.tools.<category>.<tool_module> import <tool_function>


def create_mock_ctx():
    """Create a mock MCP Context object (pattern from tests/conftest.py)."""
    ctx = MagicMock()
    ctx.report_progress = AsyncMock()
    ctx.info = AsyncMock()
    return ctx


async def main():
    ctx = create_mock_ctx()
    try:
        result = await <tool_function>(
            # Your parameters here
            ctx=ctx
        )
        print("Success! Result:")
        print(result)
    except Exception as e:
        print(f"Error: {type(e).__name__}: {e}")
        import traceback
        traceback.print_exc()


if __name__ == "__main__":
    asyncio.run(main())

4. Run Your Test Script

python /tmp/claude/.../scratchpad/your_test_script.py
