Tool Chain Integration Testing Skill

What These Tests Do

Integration tests simulate the model's tool-calling behavior by directly invoking MCP server tools in the sequence defined by each use case in the PRD. They verify that the tool chain produces correct results end-to-end — but they do NOT test the model's ability to select the right tools (that's the model-behavior test suite).

Think of it this way:

• Unit tests verify each tool works alone
• Integration tests (this skill) verify tools compose correctly
• Model behavior tests verify the LLM picks the right tools
