Function extractToolName

pkg/toolvalidation/readonlyhint.go:243–256

extractToolName returns the literal value of the Name field of an mcp.Tool composite literal, or empty string if the value is not a basic string literal. Interpreted ("...") and raw (`...`) string literals are handled via strconv.Unquote so embedded escapes are decoded correctly; the raw literal val

(cl *ast.CompositeLit)

// strconv.Unquote so embedded escapes are decoded correctly; the raw
// literal value is returned as a best-effort fallback if unquoting fails.
func extractToolName(cl *ast.CompositeLit) string {
	v := findFieldValue(cl, "Name")
	if v == nil {
		return ""
	}
	bl, ok := v.(*ast.BasicLit)
	if !ok || bl.Kind != token.STRING {
		return ""
	}
	if unq, err := strconv.Unquote(bl.Value); err == nil {
		return unq
	}
	return bl.Value
