Struct echoTool

internal/agent/agent_test.go:23–23

The agent loop prints `[tool] …` lines and assistant text to stdout by design (chapter 01). Tests don't silence them — running `go test -v` will interleave that output with the test runner's. Run without -v for a quiet pass/fail summary. echoTool is the minimal tool.Tool used by tests that need a re

// tool but don't care about its behavior. It returns its raw input as the
// "tool result" so test code can confirm the agent's dispatch is wired up.
