// ReadmeNoProto is the default README: handlers are reflection-based, so
// there is no proto generation step and no protoc prerequisite.
ReadmeNoProto = `# {{title .Alias}} Service
Generated with
` + "```" + `
micro new {{.Alias}}
` + "```" + `
## Getting Started
Run the service — no code generation, no protoc, nothing else to install:
` + "```bash" + `
go run .
` + "```" + `
Handlers are registered by reflection from plain Go types, so request and
response structs are defined directly in ` + "`handler/`" + `. To use Protocol
Buffers instead, regenerate with ` + "`micro new {{.Alias}} --proto`" + `.
## MCP & AI Agents
This service is MCP-enabled by default. When running, AI agents can discover
and call your service endpoints automatically.
**MCP tools endpoint:** http://localhost:3001/mcp/tools
### Test with curl
` + "```bash" + `
# List available tools
curl http://localhost:3001/mcp/tools | jq
# Call the service via MCP
curl -X POST http://localhost:3001/mcp/call \
-H 'Content-Type: application/json' \
-d '{"tool": "{{lower .Alias}}.{{title .Alias}}.Call", "arguments": {"name": "Alice"}}'
` + "```" + `
### Use with Claude Code
` + "```bash" + `
# Start MCP server for Claude Code
micro mcp serve
` + "```" + `
### Writing Good Tool Descriptions
AI agents work best when your handler methods have clear doc comments:
` + "```go" + `
// CreateUser registers a new user account with the given email and name.
// Returns the created user with their assigned ID.
//
// @example {"email": "alice@example.com", "name": "Alice Smith"}
func (s *Users) CreateUser(ctx context.Context, req *CreateRequest, rsp *CreateResponse) error {
// ...
}
` + "```" + `
See the [tool descriptions guide](https://go-micro.dev/docs/guides/tool-descriptions) for more tips.

make build # Build binary
make test # Run tests
make dev # Run with hot reload (requires air)
